A virus that hides within the host cell for up to years is going through the _______ cycle.
Lytic
Lysogenic
How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though the look and perform completely different?
The two different cells become mutated
The proteins expressed in each cell are different
They actually have different DNA in the two types of cells.
The genome of the different cells changes
RNA transcription
Why do identical twins begin to look different as they age?
Their environment causes mutation of the MAOA gene.
Mutations accumulate which deactivates histone proteins.
Exposure to different environments causes the addition of epigenetic tags that result in changes in gene function.
The DMNT gene is silenced.
What mutation has occurred here?
T-G-A-C-C-A
T-G-A-G-C-A
Substitution
Deletion
Insertion
Frameshift
Which of the following would result in a frameshift mutation?
Insertions only
Substitution only
Deletion only
Insertions and Deletions
Why are insertion and deletion (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.
If cancer occurs in a somatic cell, can it be passed on to the offspring?
No
