Answer: Option B

Explanation: The thin layer that forms the outer covering of the cell is known as the cell membrane. It is composed of the lipid bilayer which as embedded proteins.

This membrane is selectively permeable which means it allows only specific molecules to pass through them.

The main function of cell membrane is to protect the cell from the outer environment and by the invasion of harmful bacteria and viruses.

you are studying a bacteria plasmid that contains 5 operons and 15 genes. how many transcriptional promoters are on this plasmid
mojhsa [17]

Numerous catabolic operons have their transcription controlled by glucose. The three enzymes needed for conversion are encoded by the operon's five structural genes.

<h3>How many genes are there in an operon?</h3>

Operons have a transcription promoter at the beginning, two to twelve genes on average, and a transcription terminator at the conclusion (Zheng et al. 2002; Lawrence 2003).

<h3>Yes, there is just one promoter for operons.</h3>

An operon is a group of genes that all use the same transcriptional promoter. Every operon contains regulatory DNA sequences that act as binding sites for regulatory proteins that either promote or inhibit transcription.

<h3>The promoter is a 3 or a 5?</h3>

An area of DNA known as a promoter is where RNA polymerase starts to transcribe a gene. Promoter sequences are often found directly in the genome.
