If viruses that normally form envelopes were prevented from budding would they still be infectious?
Yes, viruses that normally form envelopes through budding would still be infectious if prevented from budding. Envelopes are important for entry into host cells, but not essential for viral infectivity as the viral genetic material inside the envelope can still be released into host cells, causing infection.
"Coli" is often short for Escherichia coli, a type of bacteria commonly found in the intestines of humans and animals. E. coli can be both beneficial and harmful; some strains can cause food poisoning and infections, while others play a role in digestion and the production of certain vitamins.
What molecule contains all of the codons needed to produce a particular polypeptide?
A single mRNA molecule has 3 codons i.e. 1 amino acid. The question is flawed and does not make sense!
Yes, DNA helicase is an enzyme that plays a critical role in DNA replication by unwinding the double-stranded DNA helix to allow other enzymes to access the genetic information for replication or repair.
C2H4 is it molecular or ionic?
No, this molecule is not ionic. It is composed of all non metal atoms. In order to be ionic, the compound should consist of the following combinations: metal + nonmetal, or metal + polyatomic ion, or 2 polyatomic ions together.
What are the recombinant DNA is formed by joining DNA molecules?
Recombinant DNA is formed by joining DNA molecules from different sources using enzymes, such as restriction enzymes and DNA ligase, to cut and connect the DNA sequences. This process allows for the creation of new combinations of genetic material that may not naturally occur. Recombinant DNA technology is widely used in genetic engineering and biotechnology for various applications.
How do hydrogen bonds between molecules occur?
Water is a polar molecule. It is made up of 2 H and an O.
The O as you will see is very small and highly electronegative. Therefore, it will tend to pull the electrons closer to itself. In doing so, it makes itself slightly more negative and the hydrogens more positive. Hence the partial +ve and -ve charges on the water molecule.
Now, the slightly negative O will attract the slightly +ve H of the other water molecules around him thus forming a bond called the hydrogen bonds
How can tools of molecular biology be used to compare the DNA of two individuals?
Molecular biology tools can be used to compare the DNA of two individuals by performing techniques such as polymerase chain reaction (PCR) to amplify specific genetic regions, followed by DNA sequencing to identify variations in nucleotide sequences. These variations, or genetic polymorphisms, can provide information about genetic relatedness, ancestry, and susceptibility to certain diseases.
Why does non polar molecules repel water molecules?
Because it is like a magnatizing ordeal so to say and it just bounces of non polar molcuels. :)
Why is important for forming complicated molecules?
it can form four covalent bonds
it forms very strong bonds
How does molecular biology prove evolution?
ERV stands for endogenous retroviral insertion. These are introns, genetic sequences that do not express proteins. In addition, viral insertions are foreign, they are not part of the original host organism. When we find common ERVs in the DNA of Humans and other primates, the only reasonable explanation is that these species share common ancestry. It would be extremely unlikely the same ransom code would just happen to infect unrelated species in the same location of a chromosome. Mitochondrial DNA are another example. The Mt DNA of humans and chimps are very similar. Yet we have grown rabbits with cow Mt DNA. There is no reason mitochondria, which are organelles with their own DNA passed down through the maternal line (sperm Mt DNA are jettisoned), must be similar, as cow and rabbit experiments show. Yet the more closely animals are related, the closer their Mt DNA align. Shared ancestry beautifully explains this result. Were all species created simultaneously, we would expect the Mt DNA to all be identical, or equally varied across species which cannot interbreed. We would NOT expect the Mt DNA to align with evolutionary pathways unless evolution was accurate. It does not support evolution. It is actually DISPROVING it.
"As the number of unexplained, irreducibly complex biological systems increases, our confidence that Darwin's criterion of failure has been met skyrockets toward the maximum that science allows." (Darwin's Black Box---The Biochemical Challenge to Evolution, Michael J. Behe, pages 39-40) If you didn't quite get that, it basically means that recent findings in the field of molecular biology raise serious doubts about the truth behind Darwin's theory.
What is gene in molecular biology?
A gene is a unit of heredity that is passed down from parents to offspring and contains instructions for building and maintaining an organism. Genes are made up of DNA and provide the code for producing proteins, which carry out various functions within cells. Mutations in genes can lead to genetic disorders or variations in traits.
If you live in Jamaica what subject do you need to study to become a veterinarian?
Jamaica's requirements for veterinary education are similar to those in countries around the world - you would need to attend a school of veterinary medicine and complete the full curriculum. This will cover anatomy, physiology, pathology, epidemiology, pharmacology, molecular biology, technical skills and communications at a minimum.
How does the inheritance of x-linked traits differ from that of other traits?
X- linked traits can only be inherited through the x-chromosome, while other traits are inherited either by both the x and y chromosome or just the y-chromosome.

Is anhydrous H2CO3 ionic or molecular?
Anhydrous H2CO3 (carbonic acid) is molecular, not ionic. It does not dissociate into ions in the absence of water.
Is P2O5 a molecular or ionic compound?
P2O5 is a molecular compound. It consists of P-O covalent bonds between the atoms, forming a covalent molecule.
Difference between biology and cell and molecular biology?
Cell biology is the study of the Life of Cells, and molecular biology is the study of the Life of Bio-molecules.
Cellular Biology is called Histology [Cells into Tissues] while Molecular Biology is called Biochemistry [Bio-molecules into Cells].
What are the important contributions of James Watson?
Discovered DNA, professor of Biology at Harvard , Nobel prize in 1962, wrote a book called THE DOUBLE HELIX , uncovered the molecular nature of cancer, ran the human genome project and identified 50,000 to 100,000 genes.
Changing the DNA of an organism is called?
Changing the DNA of an organism is called genetic engineering. The organism that results is called a genetically engineered organism. The use of this method is so widespread that it has been given its own category - recombinant DNA technology (a branch of molecular biology)
What are the molecular linking steps from a gene to its final expression as a obvious phenotype?
The molecular linking steps from a gene to its final expression as a visible phenotype involve transcription of the gene into mRNA, translation of mRNA into protein, post-translational modifications of the protein, protein folding, protein trafficking to the correct cellular location, and protein-protein interactions to carry out its function. These processes are tightly regulated by various factors to ensure proper gene expression and phenotype manifestation.
How does cell biology similar to molecular biology and molecular genetics?
Cell biology - study of whole cells and their organelles
Molecular Biology - study of the molecules & their interactions in the cell
Molecular genetics - study of the genes at their molecular levels
all of them are interrelated to one thing i.e. cell
The bottom line of all life is the DNA... Previously, we compared fossils and created evolutionary trees on the basis of structure and similarity. However, this can just be a co-incidence.
Now we can compare molecular data, DNA and protein sequences and obtain the similarity and thereby predict, why our brothers in the evolutionary tree are different than us.
Is acetic acid ionic or molecular?
Acetic acid in pure form is molecular and has covalent bonds, but when dissolved in water it dissociates into acetate anions and hydrogen cations.
This is known as the electron transport chain, which occurs during cellular respiration and photosynthesis. Electrons move along a series of carrier molecules embedded in the inner mitochondrial membrane or thylakoid membrane, releasing energy that is used to generate ATP or NADPH, respectively. The flow of electrons helps create a proton gradient that drives ATP synthesis.
Why should you choose biology as your subject?
Biology is great! If you like animals, plants and the environment or you are just interested in how things work, then Biology is right for you! Good things..... Great field trips like going rockpooling or behind the scenes at the zoo, Really cool way to do a science subject.It is so fun!!!
