DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is found in the cytoplasm of the cell and has the anti-codon on it which is complimentary to the codon. This molecule carries or transfers amino acids to the ribosome to be put together in a specific order to make a protein
A
mRNA
B
tRNA
C
DNA
D
Nucleotide
Explanation: 

Detailed explanation-1: -The tRNA is located in the ribosome’s first docking site. This tRNA’s anticodon is complementary to the mRNA’s initiation codon, where translation starts. The tRNA carries the amino acid that corresponds to that codon.

Detailed explanation-2: -An anticodon is a trinucleotide sequence located at one end of a transfer RNA (tRNA) molecule, which is complementary to a corresponding codon in a messenger RNA (mRNA) sequence.

Detailed explanation-3: -The decoding site, or the ribosomal A-site, is the site where the codons form a short, double-stranded RNA helix with the anticodons on the ribosome. It is situated in the neck region between the head and the body of the ribosomal small subunit.

Detailed explanation-4: -Transfer RNA (tRNA) Transfer RNAs (tRNAs) contain an anticodon sequence which pairs with complementary mRNA codons. The conserved, three-dimensional shape of tRNAs arises in part from the interaction between bases in different regions of the RNA sequence.

Detailed explanation-5: -Transfer RNA, or tRNA, located in the cytoplasm of the cell, ferries amino acids to form protein polypeptide chains in the ribosome. The structure of tRNA is key to its job: one side attaches to a specific amino acid, and the other end, called the “anticodon, ” matches with a corresponding segment on the mRNA molecule.
