To synthesize RNA from a DNA template
B
To facilitate the binding of tRNA to mRNA

To replicate DNA strands
D
To transport amino acids to the nucleus
Verified step by step guidance
1
Understand the process of translation: Translation is the process by which the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids in a polypeptide chain.
Identify the role of ribosomes: Ribosomes are the molecular machines that facilitate the translation process. They are composed of rRNA and proteins and are found in the cytoplasm.
Explore the function of ribosomes in translation: Ribosomes bind to mRNA and provide a site for tRNA molecules to attach. Each tRNA carries a specific amino acid and matches its anticodon with the codon on the mRNA.
Facilitate peptide bond formation: As tRNA molecules bring amino acids to the ribosome, the ribosome catalyzes the formation of peptide bonds between adjacent amino acids, elongating the polypeptide chain.
Clarify the incorrect options: Ribosomes do not synthesize RNA from DNA, replicate DNA strands, or transport amino acids to the nucleus. Their primary role is to facilitate the binding of tRNA to mRNA during translation.
