Review 6A

Gene expression

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

Multiple Choice

In a bacterial cell lacking the lac operon, which molecular process is most directly affected when considering the absence of lac operon regulation?

• Translation

• Transcription

• Replication

• Post-translational modification

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

Hotspot

In the provided diagram of a DNA molecule, please click on the regions that represent the DNA backbone. Select all.

X = hydrogen bond

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

Hotspot

In the given diagram of a DNA molecule, please identify the locations where hydrogen bonds form between the base pair. Select all.
