Hint: Transcription is the process of copying (transcription) a gene's DNA sequence to create an RNA molecule. The main transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription begins (directly or through helper proteins).
Complete answer:
Transcription is the process of copying information from a strand of DNA into a new messenger RNA molecule (mRNA). DNA maintains genetic material in the nucleus of cells as a reference, or template, in a secure and stable manner. Meanwhile, because it conveys the same information as DNA but is not employed for long-term storage and can freely depart the nucleus, mRNA is made to copy its information to protein. Because its sequence is complementary to the DNA template, the mRNA is not an exact replica of the DNA segment, even though it includes the same information.
Transcription is carried out by the enzyme RNA polymerase and a group of proteins known as transcription factors. Enhancer and promoter sequences are DNA sequences that transcription factors can bind to in order to recruit RNA polymerase to a specific transcription site. The transcription initiation complex is formed by the transcription factors and RNA polymerase working together. The RNA polymerase starts mRNA synthesis by matching complementary nucleotides to the initial DNA strand, which is initiated by this complex.
The mRNA molecule is lengthened, and transcription is stopped after the strand is fully produced. During the translation process, the freshly generated mRNA copies of the gene serve as blueprints for protein synthesis.
Note:
Transcription is a crucial step in converting the information from our DNA's genes into proteins. Proteins are the essential molecules that give cells their shape and allow them to function. Because no new RNAs—and consequently no new proteins—can be generated when transcription is blocked with mushroom toxin, it causes liver failure and death.
