Respuesta :
The molecules that will be labeled will be both proteins and nuclei acids. This is because both proteins and amino acids contain nitrogen. Proteins are large, complex molecules that play many critical roles in the body. They perform many of work in cells and are required for the structure, function, and regulation of the body's organs and tissues. Amino acids are the building blocks of proteins and are made amine groups which contain radioactive nitrogen, while nucleic acids contain nitrogenous bases with radioactive nitrogen.
Cells are the fundamental unit made up of various macromolecules. The N- 15 radioisotope will label nucleic acid and proteins of the cell.
What are proteins and nucleic acids?
Proteins are the macromolecules composed of the monomeric units of amino acids and are composed of carbon, nitrogen, hydrogen, and oxygen as the main element.
Nucleic acids are also major macromolecules that include DNA and RNA that consists of the nitrogen atom and are critical in the genetic coding.
The amine group of the amino acid and the nitrogenous base of the nucleic acids contains the radioactive nitrogen labeling.
Therefore, proteins and nucleic acids molecules will be labeled.
