what is DNA? what is RNA?

Answer 1

DNA stands for Deoxyribonucleic Acid. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules. The DNA segments that carry genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the expression of genetic information.

In eukaryotes such as animals and plants, DNA is stored inside the cell nucleus, while in prokaryotes such as bacteria and archaea, the DNA is in the cell's cytoplasm. Unlike enzymes, DNA does not act directly on other molecules; rather, various enzymes act on DNA and copy its information into either more DNA, in DNA replication, or transcribe it into protein. Other proteins such as histones are involved in the packaging of DNA or repairing the damage to DNA that causes mutations.


The structure of part of a DNA double helix.DNA is a long polymer of simple units called nucleotides, which are held together by a backbone made of sugars and phosphate groups. This backbone carries four types of molecules called bases and it is the sequence of these four bases that encodes information. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA. These RNA copies can then used to direct protein synthesis, but they can also be used directly as parts of ribosomes or spliceosomes.

RNA stands for Ribonucleic Acid. Ribonucleic acid (RNA) is a nucleic acid polymer consisting of nucleotide monomers. RNA nucleotides contain ribose rings and uracil unlike deoxyribonucleic acid (DNA), which contains deoxyribose and thymine. It is transcribed (synthesized) from DNA by enzymes called RNA polymerases and further processed by other enzymes. RNA serves as the template for translation of genes into proteins, transferring amino acids to the ribosome to form proteins, and also translating the transcript into proteins.

Answer 2

DNA is a short abbreviation for deoxyribonucleic acid. It has double stranded, and it contains four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Also, A pair with T, and G pair with C.

Ribonucleic acid (aka RNA) is mostly has single stranded. It is similar to DNA, where it has 4 chemical bases A, G, C, but instead of having T, RNA has Uracil. Also it is a ribose, rather than the deoxyribose.

here is a comparison between DNA and RNA:
DNA:
1) Has A-T, C-G.
2) double-stranded
3) had deoxyribose
4) has 1 hydroxyl group attach to the 3' position

RNA:
1) Has A-U, C-G
2) mostly single-stranded
3) has ribose
4) has 2 hydroxyl group attach to the 3' position

Answer 3

Everything except for e is technically correct. RNA is transcribed by the ribosome, not produced by. D can be different depending on the situation; like for example, RNA, not DNA, is used in the HIV virus because RNA is somewhat more stable and more useful in a retrovirus. B is commonly true, but to the best of my knowledge, double stranded RNA does exist.

Answer 4

to make it simpler...
DNA is the fixed information inside the nucleus.. The RNA is a one strand copy of the DNA...it moves from the nucleus and into the ribosome. The ribosome makes protein molecules base on the information in the RNA.

Answer 5

DNA is deoxyribonucleicacid and RNA is ribonucleic acid. RNA has to do with ribosomes, and DNA has to do with keeping information in a cell.

Answer 6

DNA stands for Deoxiribonucleic acid, basically meaning the nucleic acid that is stored in the nucleus of our cells. RNA stands for Ribonucleic acid, basically meaning the nucleic acid that DNA creates inside the ribosomes of the cell. This is basic biology. The next time you have a simple question like this one I suggest you refer to your biology book first.

Answer 7

DNA (deoxyribonucleic acid), which carries the hereditary information from generation to generation

RNA (ribonucleic acid), which delivers the instructions coded in this information to the cell's protein manufacturing sites.

Unlike enzymes, DNA does not act directly on other molecules; rather, various enzymes act on DNA and copy its information into either more DNA, in DNA replication, or transcribe it into protein. In chromosomes, chromatin proteins such as histones compact and organize DNA, as well as helping control its interactions with other proteins in the nucleus.

Answer 9

DNA is deoxyribonucleic acid that holds over genes and is double gelix stranded and RNA is ribonucleic acid that has a copy of our genes and is only single stranded.

Answer 10

DNA is deoxyribonucleic acid that holds over genes and is double gelix stranded and rna is ribonucleic acid that has a copy of our genes and is only single stranded.
