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:

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
