Which feature of DNA enables it to store genetic information and transfer this information?
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
What are the features of DNA and RNA?
Summary: Features of DNA and RNA
| DNA | RNA | |
|---|---|---|
| Function | Repository of genetic information | Involved in protein synthesis and gene regulation; carrier of genetic information in some viruses |
| Sugar | Deoxyribose | Ribose |
| Structure | Double helix | Usually single-stranded |
| Bases | C, T, A, G | C, U, A, G |
How does the structure of the DNA molecule allow it to store information?
DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix. Taken as a whole, this package of DNA serves as its owner’s complete genetic blueprint.
What is the molecular structure of DNA and RNA?
Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell’s activities, while RNA converts that code into proteins to carry out cellular functions.
What does DNA & RNA stand for?
Deoxyribonucleic acid
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. These distinctions enable the two molecules to work together and fulfil their essential roles.
What are RNA and DNA examples of?
Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds. Nucleic acids can be found within the nucleus and cytoplasm of our cells.
What feature of DNA most directly makes it an ideal molecule for storage of the genetic material?
The double-helical structure of DNA is ideally suited for repair because it carries two separate copies of all the genetic information—one in each of its two strands.
How does RNA store information?
The genetic information is first copied to another nucleic acid polymer, RNA (ribonucleic acid), preserving the order of the nucleotide bases. Genes that contain instructions for making proteins are converted to messenger RNA (mRNA).
