Question

Answer the following questions about the structure of DNA. i) State the type of bonding between the nitrogenous bases. ii) Name the complementary base pairs. iii) Explain what is meant by antiparallel strand in DNA. iv) State how many strands are there in DNA?​

Answer 1

Answer:

1) The adenine are always pairs with thymine with double hydrogen bonds while cytosine always pairs with guanine with triple hydrogen bond.

2) Name the complementary base pairs.

Ans. Adenine and thymine. Guanine and Cytosine.

Explanation:

3) Explain what is meant by antiparallel strand in DNA.

Ans. In DNA the thymine is present in the opposite of adenine this is called antiparallel strand.

4) State how many strands are there in DNA?

Ans. DNA is a double stranded coiled structure.
