DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An error in DNA replication can cause
A
mutations
B
cancer
C
genetic variations
D
all of the above
Explanation: 

Detailed explanation-1: -But some replication errors make it past these mechanisms, thus becoming permanent mutations. These altered nucleotide sequences can then be passed down from one cellular generation to the next, and if they occur in cells that give rise to gametes, they can even be transmitted to subsequent organismal generations.

Detailed explanation-2: -Extremely inaccurate DNA replication can lead to a rapid accumulation of mutations that disrupts cellular processes needed for viability and extinguish clonal populations of cells within several generations [3, 4].

Detailed explanation-3: -During the process of DNA replication, errors can sometimes occur. Nucleotide bases may be inserted, deleted, or mismatched into the DNA strand incorrectly. For this reason, it is important for the biological system to have mechanisms in place to detect and repair these errors.
