Answer:
4
Explanation:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
Answer:
The three mains in the process of DNA replication are 1 initiation 2 elongation 3 termination.
Explanation:
Enzymes those function during initiation
1 Helicase.
2 single strand binding protein.
3 Topoisomerase.
Enzymes those function during elongation
a DNA polymerase alpha
b DNA polymerase delta
c DNA polymerase epsilon
Enzymes those function during termination
1 Replication protein A
2 Replication factor C
Telomeres are protective sequences of nucleotides found at the ends of chromosomes,Which become shorter every time a cell divides.
A gradual degeneration of an organism occurs, resulting in ageing.
However, some cells are able to replenish their telomeres using the enzyme telomerase.
