Simora [160]

Answer:

The question lacks options, the options are:

A) 1 out of 16

B) 3 out of 16

C) 6 out of 16

D) 9 out of 16

The answer is 1 out of 16

Explanation:

This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.

When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.

9 represents offsprings that are dominant for both traits

The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.

1 represents offsprings that are homozygous recessive for both traits.

Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.

A particular protein largely lacks both secondary and tertiary structure. which factor, if any, is mainly responsible for the re
NemiM [27]

Entropy, is mainly responsible for the resting state of this protein.

Hydrogen bonds, disulfide bonds, and dipole-dipole interactions produce the complicated folding styles seen in secondary and tertiary structure. however, if a protein does not have these elements of structure, it'll undertake a kingdom in which its entropy is maximized.

Secondary shape is determined through hydrogen bonding within the amino acid chain backbone. Tertiary structure is the entire protein's form, decided Entropy Interplay and hydrophobic forces. The tertiary shape of a protein is the 3 dimensional shape of the protein. Disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions all affect the form a protein takes.

The nonpolar amino acids have formed the nonpolar center of the protein, weak van der Waals forces stabilize the protein. furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids make a contribution to the tertiary structure.

Disclaimer: your question is incomplete, please see below for complete question

A. Entropy

B. Hydrogen bonds between amino acid residues

C. Dipole-dipole interactions

D. None of the above
