Question

Which of the following are correct statements about the roles of DNA and RNA in a cell?

I. DNA contains the genetic instructions used in the development and functioning of living cells.
II. mRNA carries the genetic code from the nucleus to the ribosome for the creation of proteins.
III. TRNA transfers the amino acid to the ribosome for the creation of proteins.
A. I, II, and III
B. II and III only
C. I and III only
D. I and II only

Answer 1

Should be the Second option

Answer 2

Correct answer - C I abs III only.

Why? - DNA contains the instructions needed for an organism to develop, survive and reproduce. Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. ... When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain.
