DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of RNA acts like a delivery truck, delivers amino acids to the ribosome for protein synthesis, and then leaves empty again, to go collect another amino acid?
A
transfer RNA
B
messenger RNA
C
ribosomal RNA
D
mitochondrial RNA
Explanation: 

Detailed explanation-1: -Transfer RNA (abbreviated tRNA) is a small RNA molecule that plays a key role in protein synthesis. Transfer RNA serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein.

Detailed explanation-2: -tRNAs (transfer RNAs) carry amino acids to the ribosome.

Detailed explanation-3: -They’re brought to the ribosome by another type of RNA, called transfer RNA, or tRNA. tRNA is like a delivery truck bringing building materials to the ribosome job site. The mRNA will act like a foreman at the ribosome, instructing the tRNA to bring in the specific amino acid to add onto the protein.

Detailed explanation-4: -transfer RNA (tRNA) – a type of RNA that is folded into a three-dimensional structure. tRNA carries and transfers an amino acid to the polypeptide chain being assembled during translation.
