Answer:
Option C, They allow random distribution of genetic material when a cell divides.
Explanation:
The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.
Chromosomes make recombination and random segregation of genetic material to form new cells. Each new cell gets equal number of chromosomes
Hence, option C is correction
Answer:
Tilt of the axis of earth and rotation of earth. but here, google "what are the causes of day and night" and you should get your answer :)
Explanation:
<span>This happens because the proteins for the ER (proteins for secretion) are translocated into the ER during their synthesis (translation) on membrane-bound ribosomes and this is called cotranslational translocation. Proteins that are destined for the ER are marked with the signal sequence (signal peptide) at the amino terminus of the growing polypeptide chain. The signal is a series of hydrophobic amino acids, usually found near the N-terminus of the protein. and it’s recognized by a protein complex called signal-recognition particle (SRP), which takes the ribosome to the ER.</span>

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.
