Question

which of these makes up a ribosome where amino acids are bonded to create proteins?
dna
mrna
trna
rrna

Explanation:

Ribosomes are made of ribosomal RNA (rRNA) and proteins. DNA is the genetic material, mRNA carries genetic information from DNA to ribosomes, and tRNA transfers amino acids. So rRNA is part of the ribosome structure where protein synthesis (amino acid bonding) occurs.

Answer:

The option with "rRNA" (the bottom - most option among the given choices: DNA, mRNA, tRNA, rRNA)
