18 sept. 2023transcription, the synthesis of RNA from DNA.Genetic information flows from DNA into protein, the substance that gives an organism its form.This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein). Transcription when there is a need for a particular gene product at a specific time or in a specific tissue.
Transcription Factor
transcription factor, molecule that controls the activity of a gene by determining whether the gene’s DNA (deoxyribonucleic acid) is transcribed into RNA (ribonucleic acid). The enzyme RNA polymerase catalyzes the chemical reactions that synthesize RNA, using the gene’s DNA as a template. Transcription factors control when, where, and how efficiently RNA polymerases function.

Stages of transcription – Khan Academy
Transcription overview. Transcription is the first step of gene expression. During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is called a bubble.

Transcription: an overview of DNA transcription (article) – Khan Academy
Transcription is the first step in gene expression. It involves copying a gene’s DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).

Transcription (biology) – Wikipedia
Transcription is the process of copying a segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA (mRNA). Other segments of DNA are copied into RNA molecules called non-coding RNAs (ncRNAs). mRNA comprises only 1-3% of total RNA samples. [1]

30 juil. 2022Step 1: Initiation. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ”read” the bases in one of the DNA strands.

Where Does Transcription Occur – Biology Wise
Where Does Transcription Occur in a Prokaryotic Cell. Prokaryotic cells are the primitive ones that lack a nucleus. This is the reason why the entire process of protein synthesis in such cells takes place in the cytoplasm. The transcription and translation is done alongside simultaneously. The process is nearly the same as in eukaryotes, but …

7.6C: Prokaryotic Transcription and Translation Are Coupled
24 déc. 2022Prokaryotic transcription is the process in which messenger RNA transcripts of genetic material in prokaryotes are produced, to be translated for the production of proteins. Prokaryotic transcription occurs in the cytoplasm alongside translation. Prokaryotic transcription and translation can simultaneously.
