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
