What is the function of RNA polymerase in protein synthesis it transcribes the DNA strand?

What is the function of RNA polymerase in protein synthesis it transcribes the DNA strand?

What Does RNA Polymerase Do? RNA polymerase is the enzyme responsible for transcribing DNA into RNA. This is the first step of gene expression. When a cell wants to produce a specific protein, it must first call over this enzyme to the section of DNA that contains the gene for the protein.

What does DNA RNA protein mean?

The central dogma of life can be defined in a fairly simple way: DNA makes RNA, which in turn makes proteins: In transcription, your genetic code is transcribed, or written, into RNA. In translation, this RNA is then translated into proteins.

Why is DNA and RNA important?

Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. These distinctions enable the two molecules to work together and fulfil their essential roles.

How important is RNA?

RNA, in one form or another, touches nearly everything in a cell. RNA carries out a broad range of functions, from translating genetic information into the molecular machines and structures of the cell to regulating the activity of genes during development, cellular differentiation, and changing environments.

Is DNA or RNA more important?

With the exception of certain viruses, DNA rather than RNA carries the hereditary genetic code in all biological life on Earth. DNA is both more resilient and more easily repaired than RNA. As a result, DNA serves as a more stable carrier of the genetic information that is essential to survival and reproduction

How did RNA become DNA?

However, single-stranded RNA is rather unstable and is easily damaged by enzymes. By essentially doubling the existing RNA molecule, and using deoxyribose sugar instead of ribose, DNA evolved as a much more stable form to pass genetic information with accuracy.

How did DNA begin?

For some time, it was believed by some molecular biologist that life originated with the appearance of the first DNA molecule! We are reasonably sure now that DNA and DNA replication mechanisms appeared late in early life history, and that DNA originated from RNA in an RNA/protein world.

Who was the first person convicted by DNA?

Colin Pitchfork

Who was the first person in the US to be convicted of a crime using DNA?

A convicted serial rapist whose case made legal history is back in court in Orange County. Tommie Lee Andrews was sent to prison nearly 30 years ago. Andrews was suspected in two dozen rapes in 1987 and became the first person in the United States convicted with DNA evidence
