|
What does DNA make and then what does the product of that make?
|
DNA makes RNA and RNA makes proteins.
|
|
|
What is a gene?
|
A gene is a region of DNA that codes for a polypeptide.
|
|
|
What is the structure and function of proteins based on?
|
It is determined by the amino acid sequence.
|
|
|
What is transcription?
|
Transcription is the process of producing RNA from DNA.
|
|
|
What are the three steps of transcription?
|
1. RNA polymerase binds to DNA and causes strand separation.
2. RNA nucleotides (bases) bind to available sites on a DNA strand. 3. RNA molecules are modified and move into the cytoplasm. |
|
|
What are the three stages of transcription?
|
The three stages of transcription are initiation, elongation, and termination.
|
|
|
What happens during initiation?
|
RNA polymerase attaches to the promoter region. It is located just before the gene to be transcribed. Initiation factors must be present.
|
|
|
What happens during elongation?
|
An RNA molecule is assembled. Primary transcript is made.
|
|
|
What happens during termination?
|
RNA polymerase reaches the terminator region and RNA polymerase and transcript are released.
