If a sRNA is bound to the ribosome binding sequence of a mRNA coding for an enzyme in a bacteria, what offect will tis have on the amount of enzyme in this cel? O Decrease O Increase

Decrease

Explanation:

Gene expression, which involves the production of useful gene products, occurs in two stages: transcription and translation. Transcription synthesizes a mRNA transcript by copying the information in the nucleotide sequence of a DNA. This mRNA sequence is then read during translation to synthesize amino acids (proteins) in a process called translation.

Translation is initiated when a transfer RNA (tRNA) binds to the binding sequence of the mRNA in the ribosome. However, gene expression (translation) in bacteria are regulated by short non-coding nucleotide sequences called small RNA or sRNA. sRNA's are regulators that inhibits translation by binding to the initiation site on the mRNA molecule, thus preventing the binding of the tRNA for translation to proceed.

If a sRNA binds to the binding site of a mRNA coding for an enzyme, it means the rate at which the enzyme (protein) will be produced will be low or not at all. Hence, there will be a decrease in the synthesis of that particular enzyme.
