Using the model below label and define the purpose of the following in relation to transcription: Promoter: Introns: Transcription Factors: Poly-A Signal Sequence: RNA polymerase: Poly-A Tail: Enhancer: Template: Transcription Start Site: Non-Template: Exons: 5' Cap:

Answer :

RNA polymerase connects to a promoter sequence close to the start of a gene to start transcription (directly or through helper proteins).

What is the primary function of RNA polymerase during transcription?

Transcribing RNA molecules using DNA as a template is the primary task of RNA polymerase. The transcription process, in which the data held in a DNA molecule is copied into a new molecule of mRNA, is greatly aided by the multi-unit intermediate enzyme known as RNA polymerase (messenger RNA).

What do exons and introns do?

Prior to the RNA molecule being translated into a protein, introns are non-coding regions of an RNA transcript or the DNA encoding it. Exons are the regions of DNA (or RNA) that contain the protein-coding information.
