Question

which describes a difference between dna and rna?
a. dna constructs proteins whereas rna translates genetic information
b. dna makes up ribosomes whereas rna transfers genetic information
c. dna translates genetic information whereas rna maintains genetic information
d. dna maintains genetic information whereas rna helps construct proteins based on genetic information

Explanation:

DNA stores genetic information. RNA has different types like mRNA (transcribes DNA info), tRNA (transfers amino acids for protein synthesis), rRNA (makes up ribosomes which are sites for protein construction). So DNA maintains genetic info and RNA helps in protein construction based on that info.

Answer:

D. DNA maintains genetic information whereas RNA helps construct proteins based on genetic information
