Answer:

DNA is most succeptible to radiation.

Explanation:

DNA is most succeptible to radiation because;

  • The radiations may break the Double strand of DNA.
  • Base pairs of DNA or sugar phosphate backbone may be broken down by  radiations (X-ray, aplha and beta particles).
  • The hydrogen bonding between nitrogen bases may be affected by radiation.

The radiations may cause mutations in DNA which effect the cell survival or correct replication.

Answer:

A. DNA.

Explanation:

Mutations which are either acquired or somatic, are the alteration of the nucleotide sequence of the genome of a DNA.

These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
