Answer:

Its a substitution mutation because one of the specific base, G is replaced by A.

This is a Point Mutation because Point mutation brings changes in the structure of a gene because of the substitutions with another base pair. Like in this case, G is substituted by A. In case of frameshift mutations, there is a change in the number of nucleotides due to either insertions or deletions of the nucleotides, which is not in this case.

The eye is an organ.why?<br>Skin is an epithelial tissue.why?<br>​
Brilliant_brown [7]

Answer:

"The organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. So as eye. Epithelial tissue helps in protection against the microbes so as skin having different layers."

Explanation:

Eye is an organ because, the organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. Similarly, inside the eyeball there is an organ which is known as retina, with is connected with the neural and epithelial tissue which helps in detection of the light which enters into the eyeball.

Skin is an epithelial tissue because, epithelial tissue helps in protection against the microbes. Similarly skin is composed of different layers of epithelial tissue which is also supported by the layers of connective tissue, helps in protection of internal organs from damage as well as dehydration.

Which one of the following is a requirement for a good primer? Select one: a. Guanine and Cytosine should make up less than half
Alex

Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.

Explanation:

Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.

A species of beetle expresses a pigment protein as an adult but not as a juvenile. The pigment is encoded by the gene PIG. A pro
Deffense [45]

Answer:

The KID protein is responsible for the no pigmentation at the juvenile stage. When the KID protein inhibits in the adult state, the pigmentation occurs in the body. This might occur because the KID protein acts as the repressor molecule and acts as a negative regulator of PIG protein.

The KID protein is responsible for pigmentation an adult stage.  Any mutation in the KID gene might result in the loss of pigmentation in the adult. The KID gene is responsible for the binding of the KID protein and mutation in this gene can lead to the arrest of KID protein. The protein is unable to release and PIG continuously repressed in the adults.
