Module 3 Regulation of gene expression

Question 1

____ The use of a gene to make a protein

Includes the synthesis of the protein by the processes of transcription of DNA and translation of mRNA

May also include further processing of the protein after synthesis

Answer 1

Gene expression

Question 2

Is transcription and translation simultaneous in eukaryotes?

Answer 2

No, only in prokaryotes

cause everything occurs in the cytoplasm

Question 3

In eukaryotic cells, gene expression is regulated at the epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels

In what levels does this happen in prokaryotes?

Answer 3

Transcriptional level

Epigenetic
Post-translational

Question 4

____
Overall process by which information encoded in a gene is converted into an observable phenotype

Answer 4

Gene regulation

Gene expression

Question 5

Why regulate gene expression? (3)

Answer 5

Adjust to sudden changes

Conserve energy

Save resources

Question 6

In ____ (all of the mechanisms involved in regulating gene expression) the most common is the regulation of ____
