In a human germ cell, a replication slippage event occurs during the round of DNA replication just before meiosis. The slippage event occurred within the DNA sequence that encodes for the first exon of the KRT1 gene. The KRT1 gene encodes for the protein keratin which is found highly expressed in skin cells. The slippage event described has the potential to result in what type of mutation?

A. a somatic missense mutation
B. a somatic frameshift mutation
C. a somatic silent mutation
D. a germline missense mutation
E. a germline frameshift mutation
F. a germline silent mutation

The correct option from the given options is E which is germline frameshift mutation.

Explanation:

As per the question  meiosis occurs in germ cell  such that this mutation result in KRT1 gene mutation while slippage mutation cause change in frame by slipping some bases during replication. So this is frameshift mutation. This mutation is such that the gene is altered so a frameshift mutation.

Explanation:

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
