Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is translation?
A
This process only opens a portion of the DNA called a gene
B
This process creates proteins, occurs in the cytoplasm, involves ribosomes, where peptide bonds are formed between amino acids, involves tRNA
C
This process only involves one enzyme
Explanation: 

Detailed explanation-1: -Translation takes place inside structures called ribosomes, which are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make a protein chain. Illustration of the molecules involved in protein translation. A ribosome is shown with mRNA and tRNA.

Detailed explanation-2: -(trans-LAY-shun) In biology, the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). The mRNA is made by copying DNA, and the information it carries tells the cell how to link amino acids together to form proteins.

Detailed explanation-3: -Translation Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.

Detailed explanation-4: -After the transcription of DNA to mRNA is complete, translation-or the reading of these mRNAs to make proteins-begins. Recall that mRNA molecules are single stranded, and the order of their bases-A, U, C, and G-is complementary to that in specific portions of the cell’s DNA.

Detailed explanation-5: -The process of polymerization of amino acid to form a polypeptide is called translation. Thus, the biological process through which protein is synthesized is called translation.
