Verified
The molecule that connects a growing polypeptide chain and mRNA is called:
A) tRNA.
B) RNA polymerase.
C) rRNA.
D) a promoter.
E) a ribosome.
Polypeptide Chain
A series of amino acids linked together by peptide bonds, forming part of or the whole primary structure of a protein.
mRNA
Messenger RNA, a type of RNA that carries genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.
Ribosome
A cellular organelle composed of RNA and proteins, found throughout the cytoplasm in cells, which is involved in decoding the mRNA to produce proteins.

Final Answer :
A
Explanation :
tRNA (transfer RNA) is the molecule that connects a growing polypeptide chain to mRNA during translation by carrying amino acids to the ribosome, where they are added to the polypeptide chain.
