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.
Explanation:
The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.
