Translation and Point Mutations

Which change below would result in a different Amino Acid? 
3'-GCT-5'

• GTT
• TCT
• TCC
• GCA

ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a 

• Insertion- Frameshift
• Deletion- Substitution
• Deletion -Frameshift
• All of the above

In a point mutation, this would have the worst effect on the function of the protein 

• an insertion or deletion near the end of a gene
• an insertion or deletion at the beginning of the gene
• an insertion at the middle of the gene
• a base substitution

Which of the following would result in a frameshift mutation?

• Insertions only
• Substitution only
• Deletion only
• Insertions and Deletions

Why is the order of amino acids so important?

• The order of amino acids dictates what shape the protein will fold into.
• It is not important. The protein folding chamber will force the protein to fold into the correct shape.

What mutation has occurred here? 
T-G-A-C-C-A
T-G-A-G-C-A

• Substitution
• Deletion
• Insertion
• Frameshift 

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

The process to go from mRNA to a protein is called ____

• transcription
• rRNA
• replication
• translation

The main function of tRNA is to...

• carry a message that, when translated, forms proteins
• form a portion of ribosomes
• string together complementary RNA and DNA strands
• bring amino acids from the cytoplasm to the ribosomes

What amino acid is represented by the codon UUA?

• Phenylalanine
• Tyrosine
• Leucine
• Stop codon
