RNA

Describe how transcription occurs.

Transcription starts in the nucleus where enzymes bind to DNA to create mRNA. mRNA then takes that code out of the nucleus into the cytoplasm to meet with a ribosome.

Explain how translation works.

Translation happens outside of the nucleus in the cytoplasm, where a ribosome will attach to the mRNA and “read” the sequence. Then the ribosome calls for tRNA that will bring the correct amino acids to the mRNA.

What does “A” translate to in the transcription process?

U

What does “T” translate to in the transcription process?

A

What does “G” translate to in the transcription process?

C

What does “C” translate to in the transcription process?

G

What amino acid is attracted to water and will be on the outside of the protein?

Polar

What amino acid is scared of water and will be on the inside (hiding) of the protein?

Non-polar

Fill in the blank: “_____ attract”

Opposites

What is the purpose of the primary fold with a protein?

It will be the original chain and order

What is the purpose of the secondary fold with a protein?

It will form coils or sheets

What is the purpose of the tertiary fold with a protein?

The groups will either be attracted of repelled with one another

What is the purpose of the quaternary fold with a protein?

The proteins will require more units to come together for their final form

How does a DNA mutation impact a protein’s shape?

The primary structure will determine how a protein will fold. If this changes, the amino acids won’t fit together

What is the
