Answer #1

Ans:

DNA Structure

A. The components of a nucleotide:

- There are three components of a nucleotide.

1. Deoxyribose: It is a pentose sugar with five carbon atoms.

2. Nitrogenous bases: There are two types of nitrogenous bases as purines and pyrimidines.( Adenine, Thymine, Cytosine, Guanine )

3. Phosphate: Phosphate groups are alternate with deoxyribose sugar.

B. The bases in DNA:

- Pyrimidines of DNA are cytosine and thymine.

- The purines are adenine and guanine.

- Thus, there are four bases in DNA Adenine (A), Guanine (G) , Cytosine(C) and Thymine(T).

During DNA replication, after adding each nucleotide to a new strand of DNA, DNA polymerase checks that the nucleotide it just added is the correct one, i.e. that it is complementary to the opposite nucleotide on the template strand. This activity is called the ____________ activity of DNA polymerase. If this activity detects that a wrong nucleotide has been added, then the _____________ activity of DNA polymerase is activated, allowing the wrong nucleotide to be removed.

Pick the statement about DNA repair that is true. Base excision repair removes bulky DNA lesions like thymidine dimers. Nucleotide excision repair is used immediately after replication to correct errors that escape proofreading. Direct repair directly changes modified bases back to their original structure. Mismatch repair reduces the fidelity of DNA polymerase. SOS repair uses DNA glycosylases to recognize and remove a specific type of modified base.
