Which statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA?
guapka [62]

"The enzyme only binds to regions of DNA known as promoters, which have specific base sequences" statement BEST explains how RNA polymerase knows where to start and stop making an RNA copy of DNA.

Option: D

<u>Explanation:</u>

Transcription is the mechanism which happens when polymerase of RNA (principal enzyme for transcription) attaches by aid proteins or personally or to a promoter segment near the gene beginning.

For generating a new molecule of RNA which is complementary, RNA polymerase utilizes one of the DNA strands or the parent strand as a template.

For an instance, trying to block mushroom toxicity transcription triggers liver failure and death, as no new RNAs and therefore no fresh proteins can be produced.

The mitotic spindles arise from which cell structure?
Lapatulllka [165]

Answer:

The correct option is : b. centrosome

Explanation:

Centrosome is a cell organelle, which acts as the microbule organizing center and also regulates the cell cycle progression in an eukaryotic cell.

During the prophase stage of the cell cycle, the centrosomes are associated with the membrane of the nucleus. The nuclear membrane ruptures during the mitosis and the interaction of the centrosome nucleated microtubules with the chromosomes leads to the formation of the mitotic spindle.

<u>Therefore, mitotic spindles arise from the centrosome.</u>
