Studied by 4 peopleOperons
________: groups of genes in prokaryotes that are controlled by a single promoter and operator.
Eukaryotes
________ can also regulate gene expression via the way DNA is wrapped around the histones.
Exons
________: coding regions of a gene that are transcribed into mRNA.
Introns
________: non- coding regions of a gene that are spliced out of the mRNA before translation.
Transformation
________: process by which a prokaryotic cell takes up foreign DNA from its environment.
Repressor
________: a protein that binds to an operator to prevent transcription.
expression
In prokaryotes, gene ________ is controlled by operons, which are groups of gene containing a single promoter and operator.
Transduction
________: the transfer of genetic material using a virus as a vector.
Activator
________ TF: a transcription factor that increases gene expression (binds to enhancer)
Operator
________: site in an operon where a repressor protein can bind to prevent transcription.
TF
Repressor ________: a transcription factor that decreases gene expression (binds to silencer)
Plasmids
________: small, circular pieces of DNA found in prokaryotic cells.
Capsid
________: the protein shell of a virus.
Histones
________: proteins that DNA wraps around in eukaryotes.
Control elements
________: regions of DNA that control gene expression.
Promoter
________: site where RNA polymerase can bind to begin transcription.
Prokaryotes
________: simple, single- celled organisms with no nucleus.
Prokaryotic DNA
________ is found in a single circular chromosome,
Lytic cycle
________: virus builds copies in cell and then bursts out.
Viral DNA
________ can take various forms, but is usually linear, and is housed in a protein shell called a capsid.
Eukaryotic DNA
________ is linear and found in the nucleus, wrapped around proteins called histones.
operator
The ________ is a site where a repressor can bind to prevent transcription.
promoter
The ________ is a site where RNA polymerase can bind to begin transcription.
