• locomotion

• translation

• heredity

Differentiation occurs when genes are expressed, and genes are expressed when proteins are made by the cell. The role of DNA in cell differentiation is -

• DNA speeds up cell division

• DNA deactivates mutant cells

• DNA has the code for making proteins

• DNA regulates the temperature of the cell

Where does transcription take place in eukaryotic cells?

• In the endoplasmic reticulum

• In the cytoplasm of the cell

• At the ribosome

• In the nucleus of the cell

Following transcription, the mRNA leaves the nucleus and binds to a ____________.

• ribosome

• cytoskeleton

• vacuole

• cell wall

What is the first thing that occurs during transcription?

• Uracil bonds to adenine.

• mRNA nucleotides form a copy of the DNA template.

• The DNA strands unzip.

• Codons are formed.

Select all activities below that occur during transcription.

• The mRNA nucleotides are brought in.

• The DNA strands within the nucleus separate.

• Amino acids are assembled into proteins.

• An mRNA strand is constructed using the DNA code.

During protein synthesis, _____________ RNA (mRNA) carries the DNA code from the nucleus.
