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

1 answer:

5 0

"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

Explanation:

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.

Anatomy Label each of the following structures or processes.

RSB [31]

Answer:

A - DNA

B - mRNA

C - nuclear pore

D - tRNA

E - ribosome

F - rRNA

Explanation:

The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.

The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.

whether or not you think humans have influenced climate change. Write 100 to 200 words and cite at least three pieces of evidenc

Nitella [24]

In my opinion, humans have influenced climate change because it has been shown that deforestation, industrial activities and urbanization increase the level of greenhouse gases.

<h3>What is global warming?</h3>

The expression global warming makes reference to the sudden increase in temperatures around the world after the industrial revolution.

In this regard, it has been shown that greenhouse gases such as CO2 can increase global warming and human activities may be associated with this process.

In conclusion, in my opinion, humans have influenced climate change because it has been shown that deforestation, industrial activities and urbanization increase the level of greenhouse gases.
