|
There are four types of tRNA:A, T, C, G.
|
|
|
Each tRNA carries a particular amino acid using a special sequence of bases called an anti-codon.
|
|
|
tRNAs have two strands.
|
|
|
tRNAs carry special sequences known as codons and carries carbohydrates to mRNA.
|
Detailed explanation-1: -All tRNAs have about 73 to 93 nucleotides that fold into four base-paired stems and three loops, a structure which looks like a clover leaf in two dimension and. it is “L” shaped in three-dimensional structure. The 3’ end has CCA sequence. Attachment of an amino acid to the 3 adenosine yields an aminoacyl-tRNA.
Detailed explanation-2: -Answer and Explanation: The statement that is correct regarding tRNA (transfer RNA) is A. It carries the appropriate amino acid to the ribosome.
Detailed explanation-3: -During translation, these tRNAs carry amino acids to the ribosome and join with their complementary codons. Then, the assembled amino acids are joined together as the ribosome, with its resident rRNAs, moves along the mRNA molecule in a ratchet-like motion.
Detailed explanation-4: -Each tRNA is designed to carry a specific amino acid that it can add to a polypeptide chain. tRNAs bring their amino acids to the mRNA in a specific order.
