What amino acid is represented by the codon UUA?
Phenylalanine
Tyrosine
Leucine
Stop codon
What is the location in the cell for translation?
nucleus
mitochondria

What is the three base sequence of mRNA that codes for a single amino acid?
Anticodon
Codon
Protein
DNA
Where in the cell does transcription occur?
nucleus
cytoplasm
ribosome
mitochondria
TGGCAAGTACGT
What is the product of transcription?
mRNA molecule
double stranded DNA
amino acids
protein
What is the correct amino acid sequence for the mRNA code AUGCCAGUAUGA
Met-Pro-Ala-Val
Met-Pro-Val
Tyr-Gly-His
Tyr-Gly-Arg-His
Why must transcription occur where DNA can be found?
because DNA can't leave the nucleus
because ribosomes are in the nucleus
because DNA polymerase is found there
because helicase unzips the DNA
How do you know when to STOP translating a strand of mRNA?
look for the STOP codon
stop at the end of the strand
you don't
when Ms. Mallouh tells me to
How do you know when to begin translating a strand of mRNA?
look for AUG
start at the beginning
look for ATG
when Ms. Mallouh tells me to
A mutation is defined as:
A change in the cell's structure
Anything that changes in an embryo
Any change in the physical features of a human
A change in the DNA sequence
A mutation in which only 1 nucleotide is changed is called a:
Frameshift Mutation
Deletion Mutation
Substitution Mutation
Insertion Mutation
ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a
Insertion
Point mutation
Deletion
Substitution
A type of substitution in which the letter changes, but the amino acid DOES NOT change is called
Missense
Nonsense
Silent
Deletion
This type of substitution mutation that codes for a stop codon
Missense
Nonsense
Silent
Deletion
A mutation where 1 amino acid changes is a
missense mutation
nonsense mutation
frameshift mutation
silent mutation
