CA#5: protein syn, mutations

Why is mRNA important?

• Contains information to make proteins

• Contains information to make DNA

• Provides energy to the cell

• Contains the information to make the cell cycle happen

During DNA Replication, which bases are complimentary?

• Adenine - Thymine / Cytosine - Guanine

• Uracil - Thymine / Cytosine - Guanine

• Cytosine - Thymine / Uracil - Guanine

• Uracil - Thymine / Adenine - Guanine

What is Gene Expression?

• Genes that are activated and deactivated

• Counting how many bases in DNA

• Looking at a persons genetic family tree

• Calculating the number of chromosomes for each organism

What happens during Transcription? (1st step of protein synthesis)

• DNA makes mRNA where A can match with U

• DNA makes mRNA where A can match with T

• DNA replicates itself

• DNA makes DNA where A can match with U

What type of mutation is shown in the picture?

• Insertion

• Deletion

• Substitution

• Point mutation

During what part of the cell cycle is DNA replicated?

• S phase

• G1 phase

• G2 phase

• Mitosis

Regulate means...

• To control

• To be regular

• the same as unregulated

• to be out of control

The mass of cells called tumors form when...

• The Cell Cycle is unregulated

• The Cell Cycle is regulated

• Protein synthesis is regulated

• Protein is unregulated

When a substitution mutation changes the amino acid, this is called

• Missense

• Nonsense

• Silent

• Deletion

When a substitution mutation changes the amino acid to a STOP, this is called

• Missense

• Nonsense

• Silent

• Deletion
