Silent mutations can have a neutral effect. Which of these is an example of a silent mutation
mRNA codon is mutated from GCU to UCU and instead of adding an alanine, a serine is added instead.
mRNA codon is mutated from AUU to AUG and instead of adding a leucine a mehtionine is added instead.
mRNA codon is mutated from AUU to AUC but both codons code for isleucine so the mutation is not a problem.
What are some external and internal factors that can cause mutations.
A chemical that causes a mutation on someones skin
An event that messes up DNA replication and or protein synthesis during interphase
Radiation can cause mutations from exposure.
When a gene or peice of DNA is mutated, this can effect the _________ made, which effects the organisms traits.
proteins
sugars
lipids
bilayers
time
Substitution means...
a base was deleted from the DNA or RNA code
a base was added to the DNA or RNA code
a base was
the wrong base is matched
Insertion is when...
the wrong bases are matched.
bases are switched in the DNA code.
an extra base or bases are added into the DNA code.
a base or bases are added into the DNA code.
A deletion is when..
bases are flipped.
an extra base or bases are added into a DNA sequence
the bases are matched incorrectly in the DNA code.
a base or bases are removed from the DNA sequence.
Which of these types of mutaions have the potential to be very dangerous?
Substitution mutation
Insertion mutation
Deletion mutation
Silent mutation
Bases are read in
three's
fives
two's
fours
Since DNA is read in threes. Inserting (insertions) or removing a base (deletions) could effect
the energy of the base
everything after it
nothing, the mutation would be silent
