6.3 review -- gene regulation

What does the EPIGENOME do?

• synthesizes proteins

• carries amino acids

• provide permanent storage of info for making proteins

• helps regulate gene expression

What do you call the chemicals that help regulate gene expression?

• DNA

• RNAs

• epigenome

• epicondyle

Synthesizes a new protein using instructions on mRNA

• translation

• transcription

• transistor

• transylvania

Copies the code for making a protein from the DNA into RNA

• transistor

• transylvania

• translation

• transcription

In prokaryotes (bacteria), a group of related genes (like those for breaking down lactose) and the operator that controls them makes up a

• operon

• intron

• exon

• xylem

In genetics, an operator does what?

• regulates access to genes by RNA polymerase

• copies the genetic code to RNA

• synthesizes a new protein

• breaks down damaged RNA

Each of your cells only produces a certain subset of all the possible proteins our body makes because

• Cells only have a subset of the genes

• Each cell has specialized ribosomes that only make certain proteins

• Cells only use certain genes

• The question is incorrect -- all cells make all proteins

What does a promoter do?

• marks the beginning of a gene to be transcribed

• makes a protein

• carries amino acids to the ribosome

• allows certain portions of the DNA to exit the nucleus

Which of the following is true?

• Each chromosome has many genes

• Each gene has many chromosomes

• Each ribosome contains DNA

• Each amino acid has the same R group

Prokaryotes (like bacteria) regulate gene expression primarily by controlling

• binary fission

• nuclear permeability

• translation

• transcription
