Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following correctly defines the job of the ribosome?
A
digestive system
B
assembly of many proteins.
C
transport of lipids around the cell
D
makes protein using amino acid
Explanation: 

Detailed explanation-1: -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-2: -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-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: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.

Detailed explanation-5: -Ribosomes get their instructions from a molecule called messenger RNA (mRNA). The mRNA is made of a sequence of RNA nucleotides that direct the ribosome. A sequence of three nucleotides makes up a portion called a codon. The codon tells the ribosome which amino acid to add to the protein.
