Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of molecule contains an anticodon and carries an amino acid to the ribosome?
A
DNA
B
mRNA
C
tRNA
D
rRNA
Explanation: 

Detailed explanation-1: -The tRNA molecule has a distinctive folded structure with three hairpin loops that form the shape of a three-leafed clover. One of these hairpin loops contains a sequence called the anticodon, which can recognize and decode an mRNA codon. Each tRNA has its corresponding amino acid attached to its end.

Detailed explanation-2: -Explanation: tRNA is a special type of RNA that has the function of forming bonds with amino acids and bringing them to ribosomes to complete translation. tRNA carries anticodons, allowing it to bind to mRNA in the active site of a ribosome.

Detailed explanation-3: -Each tRNA molecule has two distinct ends, one of which binds to a specific amino acid, and the other which binds to the corresponding mRNA codon. During translation, these tRNAs carry amino acids to the ribosome and join with their complementary codons.

Detailed explanation-4: -Anticodon 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-5: -The tRNA molecule, on the other hand, has an anticodon, which will match its complementary codon on the mRNA. There are numerous tRNA molecules that help to build a protein during this process, and each individual tRNA molecule only carries one amino acid, which matches its complementary codon on mRNA.
