Viruses can have either DNA or RNA (a virus will never have both at the same time, although some viruses can have each one separately at different stages of their life cycles). RNA viruses are much more common than DNA viruses.

What is the theoretical number of chemically different dipeptides that may be assembled from 12 different types of amino acids?
the answer is C (144). The working is: 12^2 = 144. Here 12 is the no. of different amino acids and 2 is the no. of amino acids in the chain (its a dipeptide so, 2 amino acids).
What do a bunch of amino acids put together make?
While they are derived from Deoxyribose nucleic acid triplets, the thereby derived amino-acid sequences are used to form proteins.
DNA insertion mutations may be caused by the invasion of?
Viruses
Do all living things contain DNA?
Most do. The only exceptions are some viruses, and scientists will argue till the cows come home over whether viruses count as living things or not. Some viruses have no DNA. Instead, they store their genetic instructions in RNA. Just one example: the virus that causes AIDS, namely HIV.
What's the function of TEMED?
Tetramethylethylenediamine is used with ammonium persulfate to catalyze the polymerization of acrylamide when making polyacrylamide gels, used in gel electrophoresis, for the separation of proteins or nucleic acids. Although the amounts used in this technique may vary from method to method, 0.1-0.2% v/v TMEDA is a "traditional" range.
What two organic molecules are acids?
Organic acids are acids that contain carbon. They are called caboxylic acids. Acids with hydrogen, oxygen and another compound are called oxoacids. More information can be found here: http://alpha.chem.umb.edu/chemistry/ch115/Mridula/documents/Namingacids.pdf
vruse are dna and rna?
Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.
What are the names for the monomers and polymers of nucleic acids?
monomer = amino acidpolymer = polypeptide (= polypeptide chain)A monomer is one unit in a chain of repeating units. Amino acids are assembled in cells into chains called polypeptides.A protein may consist of just one polypeptide, or more than one. For example, human growth hormone has only one chain, but hemoglobin has four.
List and describe the structural components of viruses?
Infectious particles consisting of nucleic acid encased in a protein coat and, in some cases, a membranous envelope. The smallest viruses are only 20 nm in diameter. The genome of viruses may consist of double-stranded DNA, single-stranded DNA, double-stranded RNA, or single-stranded RNA, depending on the kind of virus. Lack the enzymes for metabolism and the ribosomes for protein synthesis. Identify host cell (needed for reproduction) by a lock and key type system of outer proteins.
Why is a virus not consider as a living thing?
because it does not have all the characteristics of life. yes it may have nucleic acids giving it the ability to reproduce but that is it. it does not have movement, excretion, respiration, nutrition, and growth.
What does the typical virus look like?
Typically the protein coat, or capsid, of an individual virus particle, or virion, is composed of multiple copies of one or several types of protein subunits, or capsomeres. Some viruses contain enzymes, and some have an outer membranous envelope. Many viruses have striking geometrically regular shapes, with helical structure as in tobacco mosaic virus, polyhedral (often icosahedral) symmetry as in herpes virus, or more complex mixtures of arrangements as in large viruses, such as the pox viruses and the larger bacterial viruses, or bacteriophages . Certain viruses, such as bacteriophages, have complex protein tails. The inner viral genetic material-the nucleic acid-may be double stranded, with two complementary strands, or single stranded; it may be deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). The nucleic acid specifies information for the synthesis of from a few to 50 different proteins, depending on the type of virus ...
What are the three molecules of life?
The molecules of life are vital for the continuation of life. They are classified into four groups; proteins, carbohydrates, lipids and nucleic acids.
What diseases may lytic viruses cause?
Any type of viral infection is caused by lytic viruses. These types of infections include pneumonia, influenza, and the common cold.
What is an example of mucleic acid?
I'm uncertain what "mucleic" acids are, I think you may mean "nucleic" acid. Those are DNA-type material, used as a kind of recipe to 'make up' biological animals.
Can viruses survive cooking?
Some viruses may be able to stand the usual cooking temperatures, however, the influenza viruses and viruses that cause the common cold (and many other types) can be destroyed by normal cooking temperatures of 167-212°F [75-100°C].
What are some of macromolecules?
The literal definition of the term macromolecule implies any large molecule. The term macromolecule was coined by Nobel laureate Hermann Staudinger in the 1920s.In the context of science and engineering, the term may be applied to conventional polymers and biopolymers (such as DNA) as well as non-polymeric molecules with large molecular mass such as lipids or macrocycles. However, other large networks of atoms, such as metallic covalent networks or fullerenes, are not generally described as macromolecules.
Do ribosomes belong to a subcellular system?
Yes, they may not seems like an organelle such as mitochondria, but ribosomes are huge molecular structures, comprised of RNA(ribo nucleic acids) and proteins which carry out the proteins synthesis in cytoplasm.
