8.3 Transcription Flashcards
What is the process of transcription?
Transcription is the process by which genetic information from DNA is copied into RNA.
True or False: Enhancers are DNA sequences that increase the likelihood of transcription of a particular gene.
True
Fill in the blank: The regions of a gene that are expressed and translated into protein are called ______.
exons
What is the role of a promoter in transcription?
A promoter is a DNA sequence that initiates the transcription of a gene by providing a binding site for RNA polymerase.
During which phase of transcription does RNA polymerase synthesize the RNA strand?
Elongation
What happens during the termination phase of transcription?
During termination, RNA polymerase stops transcription when it reaches a terminator sequence in the DNA.
Multiple Choice: Which of the following is NOT a key component of the transcription process? A) RNA polymerase B) Ribosomes C) Promoter D) Enhancer
B) Ribosomes
What are introns?
Introns are non-coding regions of a gene that are transcribed into RNA but are removed during RNA processing before translation.
True or False: Transcription occurs in the cytoplasm of prokaryotic cells.
False
What is the first step of transcription called?
Initiation
