6D Gene Expression

-Controlled by
activating/deactivating gene

-Through specific
temperature control

If you ever see this picture and
there is an X, the answer is always transcription

Key words you might see on the test that is ALWAYS the answer:

-Environmental factors (temperature)

-Regulation/regulated

-Activated

-Gene Expression

Review 6A

Phosphate + Sugar = Backbone

Nitrogenous base = A/T/C/G

X = hydrogen bond

-Holds bases (A/T/C/G)
together

What affects Genetic Variation?

●

Sequence of nitrogenous bases
●

Sequence of nucleotide

​Mutation

Review 6C

DNA → mRNA = Transcription

mRNA → Protein = Translation

1.Flip numbers

2.

Turn DNA into mRNA

3.

Find protein (amino acid) using
codon chart

Hint: DNA → mRNA
C → G
G → C
A → U
T → A

1.Flip numbers

2.Turn DNA into mRNA

3.Find protein (amino acid)
using codon chart
