DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of RNA takes the amino acids to the ribosome?
A
tRNA
B
mRNA
C
rRNA
Explanation: 

Detailed explanation-1: -When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain. Then the tRNAs and ribosome continue to decode the mRNA molecule until the entire sequence is translated into a protein.

Detailed explanation-2: -Amino acids are attached to the tRNA 3′-end as a prerequisite for entering the ribosome for protein synthesis. Amino acid attachment also gives tRNA access to nonribosomal cellular activities.
