DNA polymerase is the enzyme that "unzips" the complementary DNA strands allowing mRNA to transcribe, or copy, a section of DNA.

Many people take medical transcription classes online or at their local community college. It is not necessary to attend a high-end college such as Yale or Stanford.
Transcription in prokaryotic cells begins when RNA polymerase binds to the promoter region of a gene. This binding allows RNA polymerase to start synthesizing mRNA based on the DNA template strand. The initiation of transcription is a critical step that involves recognizing specific DNA sequences and recruiting necessary factors for gene expression.
The basal transcription factors are typically defined as the minimal complement of proteins necessary to reconstitute
For the green fluorescent protein (GFP) gene to be expressed, a suitable promoter must be present to initiate transcription, ensuring that RNA polymerase can bind and start synthesizing mRNA. Additionally, the necessary transcription factors and regulatory elements must be present to facilitate the transcription process. Finally, the cell must have the appropriate cellular machinery, including ribosomes and tRNA, to translate the mRNA into the GFP protein.
A transcription factor is a type of protein that plays a crucial role in regulating gene expression. It binds to specific DNA sequences near genes, facilitating or inhibiting the transcription process by recruiting or blocking RNA polymerase and other necessary proteins. Transcription factors are essential for controlling various cellular processes, including development, differentiation, and responses to environmental signals.
The enzyme RNA polymerase transcribes DNA. This enzyme initiates transcription, joins the RNA nucleotides together, and terminates.
Transcription and translation are the two processes necessary to build a protein based upon genetic information within DNA. Transcription is the term used for the construction of a messenger RNA (mRNA) molecule based on the DNA template. Translation refers to the processes of building a protein based upon the mRNA template.
RNA play a vital role in Transcription, basically when DNA provide an information about synthesizing amino acid then Transcription occur. In transcription DNA unwind and mRNA synthesize through RNA polymerase. Intros are removed which are non coded region of DNA in nascent mRNA through splisosomes, and only Exon remains a coded region of DNA. In simple DNA dictates to mRNA about specific protein structure.
