Disulfide bonds are involved in maintaining ________ protein structure as well as the ________ level of protein structure exhibi
Whitepunk [10]

Answer:

tertiary; quaternary

Explanation:

The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.

However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.

Genes contain instructions for assembling Question 56 options: a. purines. b. nucleosomes. c. proteins. d. pyrimidines.
sergejj [24]

Answer:

c. Proteins

Explanation:

A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.
