A DNA molecule is made up of nucleotides.Each nucleotide is made up of a nitrogen base, a sugar molecule and a phosphate group. There are 4 nitrogen bases such as adenine and guanine known as purines, thine and cytosine are known as pyramidine. These nitrogenous base are arranged in a sequence attached to each other by hydrogen bonding into anti-parallel strands. Therefore, the structure of DNA is termed as the double helical model.
Answer:
D
Explanation:
Key points:
- Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence.
- During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading.
- Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.
- If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair.

The name of an organism that is used in general conversation is called the Binomial name.
<h3>What is binomial name?</h3>
Binomial nomenclature, also known as binominal nomenclature or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, though they can also be based on words from other languages. It is also known as the "two-term naming system" or "binomial nomenclature." A name of this type is referred to as a Latin name, a binomial name (which is also abbreviated to just "binomial"), a binomen, a binominal name, or another type of scientific name.
The generic name, which makes up the first part of the name, indicates the genus to which the species belongs, while the specific name, also known as a specific epithet, identifies the species within the genus. For instance, the species Homo sapiens and the genus Homo both contain contemporary humans.
