100
The process of transcription serves to create this molecule from a DNA template strand.
What is mRNA
100
During this process, the template RNA strand is "translated" into a sequence of these molecules.

What does it mean to have a gene regulated?

The gene is turned "off" or "on".

100

Short regions of DNA that can be bound with proteins.

What are enhancers?

200
During transcription, molecules are synthesized by this enzyme.
What is RNA polymerase.
200
This type of RNA "carries" target amino acids to the binding sites.
What is tRNA or transfer RNA.
200
DNA is unwound by the action of this enzyme.
What is DNA helicase.
200
Gene regulation enables what important evolutionary phenomenon in particular?
What is cell specialization.
200

This is needed for RNA polymerase to bind to initiate transcription.

What is promotor?

300

300
In order to determine when an amino acid chain is completed, a certain codon is translated. This codon is...
What is AUG
300
DNA is read in a ___ to ___ direction.
What is 5' to 3'.
300
Temporary gene regulation on the molecular level can occur by the action of...

In the presence of lactose the lac operon is

What is on?

400
List two of the three primary forms of RNA
What is messenger RNA, transfer RNA, and ribosomal RNA.
400
The AUG codon translates to what amino acid?
What is methionine.
400
Since DNA cannot be synthesized continuously on both template strands, these structures form on the lagging strand and are joined by the action of DNA ligase.
What are Okazaki fragments.
400
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...
What are exons.
