Multiple Choice
During translation in a eukaryotic cell, __________.
A
ribosomes move into the nucleus
B
tRNA carries amino acid molecules to the nucleus, where they are added to a growing polypeptide chain
C
mRNA is synthesized by the bonding of free nucleotides to the bases on the template strand of DNA
D
polypeptides are synthesized at ribosomes, according to instructions carried by mRNA
Verified step by step guidance
1
Understand the process of translation in eukaryotic cells: Translation is the process by which ribosomes synthesize proteins using mRNA as a template.
Identify the role of mRNA: mRNA carries the genetic instructions from DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.
Recognize the function of ribosomes: Ribosomes are the cellular structures where translation takes place, facilitating the assembly of amino acids into polypeptides.
Clarify the role of tRNA: tRNA molecules transport specific amino acids to the ribosome, where they are added to the growing polypeptide chain according to the sequence specified by the mRNA.
Conclude the process: During translation, polypeptides are synthesized at ribosomes, following the instructions encoded in the mRNA, which is consistent with the correct answer provided.
