What is the role of the ribosomes in building proteins?
A
To convert the sun’s energy to glucose.
B
Make energy from glucose to use to build proteins.
C
To package and label proteins into vesicles.
D
To construct proteins using information in the DNA
Explanation: 

Detailed explanation-1: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Detailed explanation-2: -Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA).

Detailed explanation-3: -To make a new protein, the genetic instructions are first copied from the DNA sequence of a gene to a messenger RNA molecule. The ribosome then “reads” the sequence on the messenger RNA, matching each three-letter “codon” of genetic code with a specific protein building block, one of 20 amino acids.

Detailed explanation-4: -Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm. Ribosomes translate information encoded in messenger ribonucleic acid (mRNA). They link together specific amino acids to form polypeptides and they export these to the cytoplasm.
