Supply the appropriate labels for all numbered parts of the illustration.
tatiyna

Answer:

This diagram depicts the phenomenon of DNA translation in the central dogma of life. Here are the labels

1. <u>RNA strand</u> because it is a sequence of four nucleotide A, G, C, U. It has Uracil, this is why it is RNA. Further, translation takes place when DNA is already transcribed.

2. <u>Ribosome</u> is a machinary for protein formation. This is because it provides right environment to transfer RNA to decode RNA strand into a protein sequence.

3. <u>Amino acid</u>: Each amino acid is carried by a transfer RNA (tRNA). The type of amino acid depends on type of tRNA. All proteins are mostly formed with 20 amino acids and so there are at least 20 tRNA.

4. <u>Polypeptide (protein) chain made up of amino acids</u>: It depicts multiple amino acids, which tRNA carries, and are bonded together through peptide bonds.

5. <u>Transfer RNA (tRNA)</u>: tRNA has a complementary sequence to RNA strand and thus it binds with right sequence. It carry an amino acid which is then bonded to another amino acid amino acid to make a polypeptide chain.
