Question

All of the following is true about DNA, except __________________.

Question 10 options:

	A) it is made by DNA replication during the S phase of interphase
	B) it is made of monomer subunits called amino acids
	C) its structure is called a double helix
	D) it codes for making proteins
	E) it is found in all organisms

Answer 1

Answer :- "B" i.e It is made of monomer subunits called amino acids.

Explanation :-

DNA= 2' Deoxyribo Nucleic Acid.

DNA is the molecule of heredity. It functions as the genes. DNA is present all cells except plant virus i.e found in almost all living organisms. In eukaryotic cells , DNA is present in the chromosome of nucleus. In addition , mitochondria and plastid also contain DNA. In eukaryotic cells DNA is in the form of double helix . In bacteria , mitochondria and plastids DNA molecules are circular. In viruses and bacteriophage they are coiled

Basically DNA is the component of a living organisms which is a polynucleotide chain made up monomers called nucleotides and this monomers are made up of deoxyribose sugar , phosphet group and nitrogenous base. This DNA molecules are the self replicable and they are replicate to form another DNA molecules in the S phase of interphase in cell cycle. And this DNA molecules transfer the signal of protein synthesis through transcription and translation i.e the codes for protein are lies in DNA.

So from the above discussion we can conclude that the DNA is a polymer which made up monomers called nucleotides not the amino acids actually proteins are made up of amino acids.

So the answer is option"B".
