Question

Fill in the blank with the best possible choice: The bla gene ___________. Key points are underlined. Group of answer choices will be transcribed by RNA polymerase to produce the bla mRNA. The bla mRNA will be translated by ribosomes to produce the bla protein, which will give bacterium ampicillin resistance. will be transcribed by ribosomes to produce the bla protein, which will give bacterium ampicillin resistance. will be translated by RNA polymerase to produce the bla mRNA. The bla mRNA will be transcribed by ribosomes to produce the bla protein, which will give bacterium ampicillin resistance.

Answer 1

will be transcribed by RNA polymerase to produce the bla mRNA.

The bla mRNA will be translated by ribosomes to produce the bla protein, which will give bacterium ampicillin resistance.

Step-by-step explanation:

The bla gene will be transcribed by RNA polymerase to produce the bla mRNA and the bla mRNA will be translated by ribosomes to produce the bla protein, which will give bacterium ampicillin resistance.

The bla gene refers to the beta lactamase gene, a gene that confer antibiotic (ampicillin) resistance on bacteria.

The order of steps in the expression of gene involves:

1. Transcription: the gene in question is transcribed in the nucleus from DNA to mRNA using an enzyme known as RNA polymerase.
2. The mRNA is then transported into the cytoplasm where it gets attached to the ribosome and tRNA and translated into protein.

Hence, the bla gene will first be transcribed into bla mRNA by RNA polymerase enzyme and the bla mRNA will then be translated to protein by the ribosome. The bla protein gives bacterium ampicillin resistance.

Answer 2

bla gene also called beta lactamase gene that encodes beta lactamase enzyme which can cleave the beta lactam ring present in some antibiotics such as penicillin,cepalosporin to make the bacterim resistant to those antibiotics.

Step-by-step explanation:

The bla gene will be transcribed by RNA polymerase to produce bla mRNA,the bla mRNA will be translated by ribosomes to produce bla protein which gives bacterium amiphicilin resistance.
