DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transfers amino acids to help assemble proteins
A
mRNA
B
tRNA
C
rRNA
D
dRNA
Explanation: 

Detailed explanation-1: -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. translation – the process in which a cell converts genetic information carried in an mRNA molecule into a protein.

Detailed explanation-2: -tRNAs bind to codons inside of the ribosome, where they deliver amino acids for addition to the protein chain.

Detailed explanation-3: -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-4: -A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time. Protein assembly continues until the ribosome encounters a “stop” codon (a sequence of three nucleotides that does not code for an amino acid).

Detailed explanation-5: -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.
