What levels of protein structure would be affected if all hydrogen bonding interactions were prevented? check all that apply?
fgiga [73]

The proteins exhibit four levels of organization:  

1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.  

2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.  

3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.  

4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.  

Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.

If a parent cell has 18 chromosomes, each daughter cell following meiosis II will have ________ chromosomes
bogdanovich [222]

Meiosis II will have 18 chromosomes.

Meiosis:

  • Somatic cells divide during meiosis, a process in which the genetic makeup or quantity of chromosomes in the daughter cells is maintained.
  • In sexually reproducing organisms, a kind of cell division known as meiosis results in a decrease in the number of chromosomes in gametes (the sex cells, or egg and sperm). Human body cells, also known as somatic cells, have two sets of chromosomes and are diploid (one from each parent).
  • A single cell splits twice during the meiosis process, resulting in four cells with half the original genetic material. These cells—sperm in men and eggs in women—are our sex cells.
