What is the function of the ribosomes?
A
Transport proteins
B
Make proteins
C
Package and ship proteins
D
Store water, food, and wastes
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: -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-3: -A ribosome functions as a micro-machine for making proteins. Ribosomes are composed of special proteins and nucleic acids. The TRANSLATION of information and the Linking of AMINO ACIDS are at the heart of the protein production process.

Detailed explanation-4: -The Ribosome’s Function: Three Stages. Ribosomes help in producing new proteins by the translational process that involves three stages: initiation, elongation and termination.

Detailed explanation-5: -If DNA is the blueprint, then ribosomes are the masons-they build the protein using amino acids as the ‘bricks’. To build proteins, the two ribosomal subunits, small and large, assemble together to form the complete ribosome. It has binding sites for mRNA and transfer RNA (tRNA) molecules.
