Coding and Non-Coding DNA Flashcards
1
Q
around what percent of our genome is coding?
A
1-2 %
2
Q
what percent of the genome is introns
A
24%
3
Q
three things in the non-coding regions
A
microsatellites
transposons
pseudogenes
4
Q
microsatellites
A
areas that have variable number tandem repeats (VNTRs)
has telomeres
5
Q
transposons
A
parts of DNA that can move to different positions in the genome of a single cell
called jumping genes
6
Q
class 2 transposons
A
consist of DNA that moves directly from place to place
7
Q
class 1 transposons
A
first transcribe the DNA into RNA and then uses reverse transcriptase to make a DNA copy of the RNA to insert into a new location
8
Q
pseudogenes
A
genomic DNA sequneces but are non funtional
9
Q
2 ways pseudogenes may arise from
A
duplication
retro transposition
