What is biotechnological genetic improvement?
Scientists often study the genome of important food producing organisms like crops and farm animals in order to make changes in the genome and produce disease resistant cops and high yielding animals. This process is generally referred to as biotechnology driven genetic improvement
Cisgenesis is genetic modification (= GM) of plants with cisgenes only.
A cisgene is a natural gene, coding for an (agricultural) trait, from the crop plant itself or from a sexually compatible donor plant that can be used in traditional plant breeding. It is in practice restricted to genes coding for dominantly inherited traits. The gene belongs to the breeder's gene pool.
What is the result in DNA turning on and turning off different sections of its information?
When DNA turns on, it activates specific genes to be transcribed into mRNA and translated into proteins. This process allows the cell to produce the necessary proteins for various functions. When DNA turns off, it suppresses the transcription of certain genes, preventing the production of specific proteins. This regulation of gene expression allows cells to respond to internal and external signals, adapt to changing environments, and maintain proper function.
Codons code for a particular amino acid with a triplet of DNA nucleotides.
There are 20 amino acids, and 4 nucleic acids. Using a single base you could only code for 4/20, with two bases 16/20, 3 bases 64/20. Therefore 3 bases are necessary to encode all of the possible amino-acids.
Is it possible to volunteer for being a test subject for human genetic engineering?
no yet...although there are certain people out there who against the law would use a human test subject...but to date it is illegal unless its been animal tested on numerous occasions and approved by the government....
Racism is not genetic. You may however, have heavy influence from those around you i.e. Parents, friends that persuade you into thinking racism is acceptable, as when you are younger, you are none the wiser. It is all determined by your environment.
Why Ribose and deoxyribose specifically included in genetic material?
The only answer I can offer (I must admit that I am not objective and promote the idea I published with my friend some two years ago) is as follows: alfa-ribopyranose (which is in solution in equilibrium with beta-ribopyranose, both furanose forms and an open form) is the easiest racemate to get separated to enantiomers in a process we call the absolute enantioselective separation (AES). It is a chromatography-like process in which the molecules to be separated are oriented in two orthogonal directions parallel to the surface. Then, in opposite enantiomers different groups are oriented towards the surface. Thus, the energy of interactions of opposite enantiomers with the surface is different and in a chromatography-like process the molecules of the opposite enantiomers will move along the surface with different rates. Additionally, AES is capable of separating not only enantiomers but other isomers (including diastereoisomers) as well. The factors that can orient molecules in (more or less) orthogonal directions that are parallel to the surface are:
1. electric field plus an interaction of molecules with a pattern on the (flat) surface or
2. interactions with two independent patterns on the (chiral) surface.
A racemate of ribose is easier to get separated to enantiomers than other mono- saccharides because in one enantiomer all four (including the anomeric one) hydroxy groups are oriented towards the surface while in the opposite enantiomer all these OH groups are oriented against the surface, and thus, the energy of interactions between the enantiomers and the surface is the largest for alfa-DL-ribopyranose. Our answer to the "why ribose" question is that (under specific conditions) it was the only mono- saccharide that could have been isolated in an enantiomerically pure form which is likely to be a necessary condition for the life emergence. [Current Organic Chemistry, 12(12) (2008), 995; Origins of Life and Evolution of Biospheres, 37(2007), 167]. The plausible answer to the question "why is ribose in the beta-furanose form" has been offered by Banfalvi [DNA Cell Biol., 2006, 25, 189].
The scientific field devoted to developing new drugs for treating genetic disorders is?
the answer is PROTEOMICS
How do you draw a genetic diagram to show if a chickens offspiring will lay a lot of large eggs?
the chicken and the cockerels have to breed in order to lay eggs
they would have genes with inherited characteristics. they would also have
some environmental characteristics like weight if you'd feed them too much.
An iPhone LIKE device NOT manufactured by Apple. A device such as this will look much like the device it represents however it will likely have many compatibility issues together with a much inferior quality.
What are the side effects of cloning?
cloning can effect the growth and cause mental problems it can also be playing god as people say.It can also fail the first times because it Dolly over 200 times to be perfect and most clones died very early
Can being a sexual abuser be genetic?
While patterns of abuse (sexual and other) are frequently passed from one generation to the next, the question remains if this is behavioral or genetic, with the majority of thought being that this is a behavioral phenomenon.
What role do ribosomes play in carrying out the genetic instructions?
it can reads the code and make new proteins
No. On the contrary, you should try to incorporate more into your diet. Try to avoid saturated fats like margarine.
What information does the Bible contain?
Answer:

Answer:
things about jesus
Male and female reproductive cells combine to form offspring with genetic material from both cells?
Yes.
What are the possible causes of genetic variation?
Anaphase 1 - the crossing over of chromosomes, they swap genetic material determining what you genetically inherit
How does the DNA replication takes place?
When DNA replication takes place weaker hydrogen bonds that join complementary bonds together become broken. The two different sides of the DNA ladder start to unravel. The parent strands, however, stay joined. The parent strands that remain become molds to nucleotides, that attach themselves to complementary bases. Polymerases fuse those free nucleotides into the DNA strand.
Step 1: A special enzyme (helicase) "unzips" the double helix that is the DNA and Single Strand Binding Proteins stabilise the structure.
Step 2: A primer with a short DNA sequence complementary to a region on the parental strand is added by a primase to allow replication to occur.
Step 3: Another enzyme (DNA polymerase) combines free-floating deoxyribonucleosides triphosphate to their corresponding nucleotides that are attached to the DNA strand, attaching the free nucleotide to the 3' OH tail of the previous section, forming a complementary strand of DNA from the 5' to 3' direction.
Really it's that easy. When it's finished, there are two identical strands of DNA, assuming no mutations occured.
