Overall, protein synthesis consists of these steps
DNA synthesis, RNA synthesis and transcription
transcription and translation
DNA synthesis, transcription and translation
it is very small and very complicated
it isn't important
it serves as the blueprint for traits of all living things
because we eat it every day for energy
What is the location in the cell for translation?
Cytoplasm
Nucleus
Lysosome
Golgi apparatus
rRNA makes up what organelle of the cell?
Nucleus

Which codon below is the code for Leucine?
UUA
UUC
AUU
CUA
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
Why are frameshift mutations so harmful?
They change all of the codons from the mutation on down the line, which changes the amino acid sequence
They insert things that an organism doesn't need.
They often delete things that organisms need.
Insertion and deletions are not any more harmful than substitution mutations.
What type of mutation is characterized by a substitution of 1 base for another base? (ex: ACG is mutated to CCG)
Frameshift
Point
Both
Neither
A point mutation in which the amino acid does not change.
Missense
Nonsense
Deletion
Silent mutation
What kind of mutation is the result of an insertion or deletion of a base? (ex: ACG mutated into ACAG)
3 bases in a row on the mRNA strand, that call for a particular amino acid to be added to the polypeptide chain:
chromosome
gene
codon
anticodon
Which mutation will cause translation to stop?
Mutations 1 and 3 only
Mutation 1 only
Mutation 2 only
Muations 1, 2, 3
ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a
Frameshift
Substitution
Point
All of the above
Which statement best defines a mutation?
a physical trait that negatively impacts the organism
an adaptive trait that allows the individual to be better fit for survival
a change in the order, number, or type of bases in the genetic code
an identical copy of the original DNA strand
Mutations that change a single base pair, usually involving a substitution of one base for another:
chromosomal mutation
polyploidy
translocation
point mutation
If a point mutation does not change the order of the amino acid sequence, this is called a:
nonsense mutation
silent mutation
missense mutation
frameshift mutation
Insertions and deletions are also known as:
frameshift mutations
chromosomal mutations
silent mutations
polyploidy
If a mutation codes for "stop" in the amino acid chain, this is called a:
nonsense mutation
missense mutation
silent mutation
frameshift mutation
If UCU is changed to UCC, this is a _______________________________.
silent mutation
missense mutation
nonsense mutation
frameshift mutation
Which of the following mutations would be the most likely to affect the resulting protein?
substitution
silent mutation
frameshift mutation
all mutations affect the resulting protein
