Stages of Transcription

Transcription is the process of copying genetic information from DNA into RNA. It take place in following stages:

Initiation: This stage marks the beginning of transcription. RNA polymerase, along with other transcription factors, recognizes and binds to the promoter region on the DNA. The DNA double helix unwinds, exposing the template strand for transcription.

Elongation: Once the RNA polymerase is bound and the DNA is unwound, the enzyme moves along the DNA template strand. As it progresses, it synthesizes a complementary RNA strand by incorporating ribonucleotides according to the DNA template. This stage continues until a termination signal is encountered.

Termination: Transcription concludes when the RNA polymerase reaches a specific termination signal on the DNA. This signal instructs the polymerase to release the newly formed RNA molecule. The DNA double helix reforms, and the RNA product is freed.

Transcription of DNA

Transcription of DNA is a cellular process where the genetic information encoded in DNA is converted into RNA. It initiates with RNA polymerase binding to the DNA at a specific promoter region. Then, the enzyme unwinds the DNA and synthesizes a complementary RNA strand by following the DNA template. This process continues until a termination signal is reached, leading to the release of the newly formed RNA molecule, which carries the genetic code for protein synthesis.

Transcription of DNA Definition

Transcription is the process of copying genetic information from DNA to RNA. It involves RNA polymerase creating a complementary RNA strand using a DNA template....

What is Transcription?

Transcription of DNA is a fundamnetal cellular process that converts the genetic information stored in DNA into RNA. Both DNA and RNA are nucleic acid. While DNA stores genetic information, RNA mostly helps in transfer and expression of information. DNA being chemically and structurally more stable is a better genetic material. The process of transcription is goeverned by the principle of complementarity. In transcription only a segment of DNA and only one of the strands is copied into RNA. This process occurs in three main stages: initiation, elongation, and termination....

RNA Polymerase

RNA polymerase is an important enzyme that take part in gene expression and the transcription of genetic information. It plays a central role in the process of transcription, where it copies DNA sequences into RNA molecules. RNA polymerase identifies specific promoter regions on the DNA, marking the initiation point for transcription. As it moves along the DNA template, RNA polymerase unwinds the double helix and synthesizes a complementary RNA strand. This synthesized RNA, primarily messenger RNA (mRNA), contains the instructions for protein synthesis. Multiple types of RNA polymerases exist, with RNA polymerase II predominantly transcribing protein-coding genes in eukaryotes. RNA polymerase regulates gene expression, enables the development and maintenance of living organisms and the functioning and regulation of various cellular processes....

RNA Processing

RNA processing is an step in gene expression, particularly in eukaryotes, where the initial RNA transcript (pre-mRNA) undergoes several modifications to become mature mRNA. These modifications include:...

Inhibitor of Transcription

Inhibitors of transcription are molecules or compounds that can interfere with the normal process of transcription. They reduces or preventes the synthesis of RNA from DNA. These inhibitors can have various mechanisms of action, such as blocking the activity of RNA polymerase or disrupting the binding of transcription factors to DNA. Some examples of transcription inhibitors includes:...

Transcription Termination

Until it receives instructions to halt, RNA polymerase will continue to transcribe. Termination, which occurs when the polymerase transcribes a DNA sequence known as a terminator, is the process of stopping transcription. There are two primary methods of transcription termination:...
