Which of the following is true regarding the machinery of translation?

a. A single mRNA can be translated simultaneously by several ribosomes.
b. tRNAs released from the ribosome are degraded B) termination and eukaryotes utilizes three different release factors.
c. Polycistronic MRNA usually has a single ribosome binding site.
e. once a single mRNA strand is translated once it is degraded

Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.

To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a polysome and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.

The true statement regarding the machinery of translation is ; ( A ) A single mRNA can be translated simultaneously by several ribosomes

Translation is the process of producing protein with the use of RNA ( i.e. the process of protein synthesis from an mRNA template ) during translation the code found in the template is converted into an amino acid sequence.

Ribosomes are composed of rRNA which directs the process of translation with the proteins and key molecules such as tRNA.

Hence we can conclude that the true statement regarding the machinery of translation is A single mRNA can be translated simultaneously by several ribosomes.
