STRUCTURE OF PROTEINS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During ____, the cell uses mRNA as a template to make proteins in the ribosome.
A
Transcription
B
Translation
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The mRNA is then pulled through the ribosome; as its codons encounter the ribosome’s active site, the mRNA nucleotide sequence is translated into an amino acid sequence using the tRNAs as adaptors to add each amino acid in the correct sequence to the end of the growing polypeptide chain.

Detailed explanation-2: -Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble-in order-the chain of amino acids that form a protein.

Detailed explanation-3: -Making proteins from mRNA is called translation.

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: -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.
