What is the role of a ribosome?
A
Link amino acids together
B
Bind messenger RNA
C
Synthesize polypeptides and proteins
D
Make other ribosomes
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: -The ribosome is the site of polypeptide synthesis. It holds the various components (the mRNA, tRNAs, and accessory factors) in appropriate juxtaposition to one another to catalyze polypeptide synthesis.

Detailed explanation-3: -A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.

Detailed explanation-4: -Synthesis of new proteins starts in the nucleus, where ribosomes get their instruction to begin the process. Sections of DNA (genes), encoding a specific protein, are copied over to messenger RNA (mRNA) strands in a process called transcription.
