Chromosomes are composed of two types of biomolecules. One of the biomolecules in chromosomes is called DNA, which functions as the genetic code. The other biomolecules in chromosomes are called histones, which bind the DNA tightly for cell division. Genes in DNA have the code for making histones. Based on the information above, which types of biomolecules are in chromosomes?

F Carbohydrates and lipids
G Proteins and nucleic acids
H Proteins and carbohydrates
J Nucleic acids and carbohydrates cationTM Inc​

Answer:

proteins and nucleic acids

histones are proteins and DNA is made up of nucleic acids (these are the macromolecules made up of nucleotides)

Explanation:

Chromosomes are thread like structure found in nucleus of cells. It contains several biomolecules in it. DNA is nucleic acid whereas histones are protein. Hence, option “ G” is correct.

What are biomolecules?

Molecules that are produced by living organisms are called biomolecules.

Example of biomolecules are Carbohydrates, Proteins, Nucleic acids and Lipids.

  • Carbohydrates are sugar molecules such as Glucose, Galactose Maltose, Fructose, Sucrose, Lactose, and Starch.
  • Protein structures are of four types primary, secondary, tertiary, and quaternary structure. Histone is a kind of a protein.
  • Nucleic acids include DNA and RNA.

Biomolecules present in chromosomes are nucleic acid (DNA and RNA) and Histone protein. Hence  option “G” is correct.
