Transcription
The process of transcription serves to create this molecule from a DNA template strand.
mRNA
During this process, the template RNA strand is "translated" into a sequence of these molecules.
amino acids.
DNA replicates by way of ___________ replication.
semiconservative
What does mean have a gene regulated?
The gene is turned "off" or "on".
During transcription, molecules are synthesized by this enzyme.
RNA polymerase.
This type of RNA "carries" target amino acids to the binding sites.
tRNA or transfer RNA.
DNA is unwound by the action of this enzyme.
DNA helicase.
Gene regulation enables what important evolutionary phenomenon in particular?
cell specialization.
Transcription is initialized by the binding of synthesis enzymes to what genomic site?
promoter region
In order to determine when an amino acid chain is completed, a certain codon is translated. This codon is...
AUG
DNA is read in a ___ to ___ direction.
5' to 3'.
Temporary gene regulation on the molecular level can occur by the action of...
transcription factors, intron splicing, etc.
List two of the three primary forms of RNA
mRNA, tRNA, and rRNA.
The AUG codon translates to what amino acid?
methionine.
Some DNA in the genome is not translated at all, but is mixed into the code that is. The parts of the genome that are expressed are called...
exons.
Transcription, and by extension, gene expression, occurs during this phase in the cell cycle.
interphase.
All amino acids contain a carboxyl group, but the 20 different molecules vary in the structure of what region of the chemical?
R group
Replication occurs in which region of the chromosome?
all of it.
DNA can be permanently deactivated by this chemical process.
DNA methylation.
