Why are skin cells undergoing mitosis continuously

Biology
1 answer:
marta [7]3 years ago
3 0
Our skin cells divide rapidly in order to maintain a protective barrier against infection.The outer skin layer is called the epidermis and contains mostly dead cells that contain keratin.Keratin is a tough fibrous protein found in hair,skin and calluses and acts as a protective coating.The epidermis cells are constantly undergoing mitosis so the outer dead cells containing keratin are rapidly replaced as they fall off, which occurs after so many days.Then the newer living cells start producing keratin,lose their cellular contents,then die and the cycle goes on.The skin acts as a barrier to infection,therefore,it's constantly renewed and repaired.

A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides
Maksim231197 [3]

Answer:

D. The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.

Explanation:

The cells of group A are prokaryotic because it is prokaryotes which do not have a double membranous structure called nucleus for storing their genetic material. The genetic material of prokaryotes is spread in the cytoplasm in the form of a circular DNA which is called as nucleoid. Since they do not have a separate organelle like nucleus for storage of their genetic material, they are bound to replicate their DNA in the cytoplasm. In contrast to prokaryotes, eukaryotes have nucleus for storage of their genetic material and in eukaryotes replication is an exclusively nuclear event.
