1

Which components are unique to RNA compared to DNA?

Deoxyribose sugar and uracil (U)

Deoxyribose sugar and thymine (T)

Ribose sugar and uracil (U)

Ribose sugar and adenine (A)

1

Which row correctly matches each type of RNA with its primary role?

mRNA – catalyzes peptide bonds; rRNA – carries codons; tRNA – stores DNA

mRNA – ribosome structure; rRNA – carries genetic code; tRNA – delivers amino acids

mRNA – carries amino acids; rRNA – template; tRNA – ribosome structure

mRNA – carries genetic code; rRNA – ribosome component; tRNA – delivers amino acids

1

Which statement best contrasts (shows differences) RNA and DNA?

Both RNA and DNA are single stranded and temporary

RNA is double stranded and stable; DNA is single stranded and temporary

RNA is single stranded and suited for temporary tasks; DNA is double stranded and suited for stable, long-term information storage

Both RNA and DNA are double stranded and permanent

1

During translation in protein synthesis, what is the main role of tRNA?

Form the structure of ribosomes and catalyze peptide bond formation

Carry genetic information from DNA to ribosomes

Replicate DNA before cell division

Deliver amino acids to the ribosome and match them to mRNA codons via anticodons

1

RNA uses the nitrogenous bases adenine (A), guanine (G), cytosine (C), and uracil (U).

True

False

1

The central dogma of molecular genetics describes the flow of information as DNA → protein → RNA.

True

False

1

mRNA is typically a linear, single-stranded molecule that serves as a template for polypeptide (protein) production.

True

False

1

rRNA’s only role is to carry amino acids to the ribosome during translation.

True

False

1

The ability of RNA to form short chains and fold into structures like hairpins helps it perform specific temporary roles in gene expression.

True

False
