Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens during translation?
A
Copying of DNA to produce DNA
B
Copying of DNA to produce mRNA
C
Copying of DNA to produce tRNA
D
Polypeptide synthesis
Explanation: 

Detailed explanation-1: -In the process, the ribosome translates the mRNA produced from DNA into a chain of specific amino acids. This chain of amino acids leads to protein synthesis. It is a process where the expense of ATP is required and this energy is given by the charged tRNA.

Detailed explanation-2: -Polypeptides often need some “edits.” During and after translation, amino acids may be chemically altered or removed. The new polypeptide will also fold into a distinct 3D structure, and may join with other polypeptides to make a multi-part protein.

Detailed explanation-3: -Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA).

Detailed explanation-4: -During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.

Detailed explanation-5: -During translation, proteins are made using the information stored in the mRNA sequence. The mRNA attaches to a structure called a ribosome that can read the genetic information.
