100

The process of transcription serves to create this molecule from a DNA template strand.

mRNA

100

During this process, the template RNA strand is "translated" into a sequence of these molecules.

amino acids.

100

DNA replicates by way of ___________ replication.

semiconservative

100

What does mean have a gene regulated?

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

200

During transcription, molecules are synthesized by this enzyme.

RNA polymerase.

200

This type of RNA "carries" target amino acids to the binding sites.

tRNA or transfer RNA.

200

DNA is unwound by the action of this enzyme.

DNA helicase.

200

Gene regulation enables what important evolutionary phenomenon in particular?

cell specialization.

300

Transcription is initialized by the binding of synthesis enzymes to what genomic site?

promoter region

300

In order to determine when an amino acid chain is completed, a certain codon is translated. This codon is...

AUG

300

DNA is read in a ___ to ___ direction.

5' to 3'.

300

Temporary gene regulation on the molecular level can occur by the action of...

transcription factors, intron splicing, etc.

400

List two of the three primary forms of RNA

mRNA, tRNA, and rRNA.

400

The AUG codon translates to what amino acid?

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...

exons.

500

Transcription, and by extension, gene expression, occurs during this phase in the cell cycle.

interphase.

500

All amino acids contain a carboxyl group, but the 20 different molecules vary in the structure of what region of the chemical?

R group

500

Replication occurs in which region of the chromosome?

all of it.

500

DNA can be permanently deactivated by this chemical process.

DNA methylation.
