Pressure increase towards earth’s interior because the further deeper you go the higher the rock layers above that apply pressure towards the center of the earth by gravity. In addition , due to this increasing pressure, temperatures also increase because the two parameters are directly proportional.

Which genetic mutation can be passed to the offspring?

Kitty [74]

Answer:

A gamete containing an extra chromosome is formed.

Explanation:

Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.

Why does synthetically produced RNase refold incorrectly if the reducing agent is removed before urea removal?

olya-2409 [2.1K]

<h2>Disulfide bonds interaction </h2>

Explanation:

The high concentration of urea causes unfolding of protein and thus results in loss of function of a protein. The urea interacts with the protein and prevents the folding of a protein.
During oxidation, the disulfide bonds that are required for proper functioning and stabilization of protein are formed, while in the presence of urea, the disulfide bonds are not positioned correctly. The protein oxidation results in covalent modification of a protein that results in the change of physical and chemical properties of a protein.
The change of physical and chemical properties of protein after oxidation and in the presence of urea cannot be modified even after the removal of urea. Thus, protein does not fold properly.
Hence the right answer is "disulfide bonds are not positioned correctly rather than week bonding interaction"
