Question

In the DNA molecule
(a) the total amount of purine nucleotides and
pyrimidine nucleotides is not always equal
(b) there are two strands which run parallel in
the 5' ➝ 3' direction
(c) the proportion of adenine in relation to
thymine varies with the organism
(d) there are two strands which run antiparallel
one in 5' ➝ 3' direction and other in 3' ➝5'

Answer 1

Answer:

d)there are two strands which run antiparallel one in 5' to 3' direction and other in 3'to5' direction.

Answer 2

(d) there are two strands which run antiparallel

one in 5' ➝ 3' direction and other in 3' ➝5'

Explanation:

DNA is a genetic material that is made up of nucleotides. Each nucleotide binds with other nucleotides by a bond that is called as phosphodiester bond. Nucleotides bind with other nucleotides and forms a long chain in a double stranded format. In double stranded format, one strand goes 5'-3' direction and other goes in 3'-5' direction. Both strands are anti-parallel to each other.
