(a) mutation is when one letter or group of letters is swapped out for another letter or group of letters.
(a) mutation are when one letter or group of letters (codon) are completely removed from the DNA/RNA sequence.
(a) mutations are when a letter or group of letters are added into the middle of the DNA/RNA sequence, extra letters occur and cause a FRAMESHIFT usually.
(a) mutations are when a letter or group of letters are DOUBLED/REPEATED when they should not be.
(a) mutation is when one letter or group of letters moves and is placed into a whole different location than they should be in.
Type of mutation that changes the DNA/mRNA sequence, but the protein that is made is the exact same as how it should be, and no effect/issues are shown.
Frameshift
Silent
Nonsense
Missense
If the original sequence is ATG CAT, but the mutation sequence is AGG CAT, what type of mutation is this?
Translocation
Deletion
Substitution
Insertion
An insertion often causes a __________ mutation, causing the mRNA to be read incorrectly, and the Amino acid sequence changes.
Nonsense
Missense
Silent
Frameshift
Mutations have an effect on the body when the (a) acid sequence is changes, causing a nonfunctioning protein to be made (shape change = wrong/no function).
For proteins, a change in the amino acid sequence leads to a change in the _____ of the protein, which can make it nonfunctional (not working), protein folds wrong.
Shape
Color
Amount
Why does the mutation that causes sickle cell anemia have an effect on the red blood cells? (What job does it affect?).
Mutations can effect what proteins the (a) makes (blank is the organelle that reads mRNA to produce polypeptides/proteins).
Once proteins are produced, they need to be (a) into their proper shape to match their function/job. This doesn't happen if the amino acid sequence is messed up in anyway.
A nonsense mutations causes an incomplete protein to be made, because the mRNA tells the ribosome to (a) building the protein and end translation. (HINT: what type of codon ENDS translation)
If the amino acid sequence of a protein changes, the job will not be performed. This protein is now called a/an ___ protein
Incomplete
Duplicated
Nonfunctioning
Shortened
AUG on mRNA means that tRNA will bring over the amino acid Methionine (Met), which is the ______________ codon. (HINT: This BEGINS TRANSLATION -> AKA Protein Synthesis)
