What is the role of RNA in transcription and translation?

a. Messenger RNA(mRNA), which carries the genetic information from DNA and is used as a template for protein synthesis. RNA takes that information into the cytoplasm, where the cell uses it to construct specific proteins, RNA synthesis is transcription; protein synthesis is translation.

What is the role of RNA in gene expression?

RNA serves as an intermediate molecule that translates the instructions from DNA into protein. During the initiation of gene expression, the DNA double helix unwinds to produce two separate strands with their amines sticking out from the backbones.

Which RNA is used in transcription?

messenger RNA (mRNA)
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

Is gene expression transcription or translation?

Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.

What are the functions of DNA and RNA in gene expression?

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

How does RNA polymerase know where to start transcribing a gene?

To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to “sit down” on the DNA and begin transcribing.

Which of the following are the functions of RNA?
