Why is it important for a cell to perform checks after DNA replication? A.
If errors are not removed from areas with a gene, then the resulting proteins could be affected.
B.
If errors are not removed from areas with a gene, then the resulting lipids could be affected.
C.
Errors in DNA replication that occur in any cell type will be passed to the offspring.
D.
Errors in DNA replication that occur in any cell type will always result in death of the cell.

A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.

Explanation:

Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.

It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.
