This is a good,bad or no change in a DNA sequence.
What is a mutation
AUG-CUC-UUG -> AUG-CUA-CUU-GA What mutation is shown here??
What is an insertion mutation or What is an insertion frameshift mutation?
All mutations are bad. True or False
If the mRNA sequence has a stop codon placed in the beginning of it what will happen?
a)Sequence will not be affected
b)sequence will have to recombine mRNA and DNA
c)Arganine will be the next protein
d)The sequence will be short and messed up
d)The sequence will be short and messed up
What type of mutation causes the entire sequence after that to be altered?
What is frameshift?
If an insertion mutation occurs what part of the sequence will be affected?
a)Nothing will be affected
b)The sequence before the insertion
c)The entire sequence
d)Where the insertion happened
d)Where the insertion happened (also after)
What effect does a Silent Mutation have?
No effect. Still codes for the same amino acid.
If the sequence AUC-GUG-CGU-ACA is changed to AUC-GAC ACA GCU- what will the new sequence code for?
a)Iso-Asp-Ther-Ala
b)Iso-Hist-Ther-Ala
c)Iso-Asp-Ther-Alg
d)Iso-Arg-Ther-Ala
a)Iso-Asp-Ther-Ala
Identify 2 examples of genetic diseases caused by mutations that we learned about.
What is Sickle cell, diabetes, cystic fibrosis, muscular dystrophy
What are the 3 point mutations?
Substitution, Insertion and Deletion
Whats the difference between a point mutation and a frames shift?
A point mutation changes a particular spot of the DNA, While frame shift moves the DNA forward or backward.
What type of mutations are frameshift mutations?
Insertion and Deletion
True or False. Mutations can be caused by various factors, including spontaneous errors during DNA replication, exposure to mutagens (chemicals or radiation), or other environmental factors.
True
What type of mutation is this?
Normal AAA ATG CTT CTC
Mutated AAA ATG TTT CTC
Substitution
Substitution is what type of mutation? Frameshift, Point or Silent?
Point mutation
