(chapter 4 :) the types of DNA in different organelles Flashcards
1
Q
what 3 organelles is the DNA in Eukaryotic cells found in
A
Mitochondria
Chloroplasts
Nucleus
2
Q
list 4 characteristics of the DNA in mitochondria and chloroplasts
A
- no introns
- circular
- shorter
- not associated with histones
3
Q
list 4 characteristics of the DNA in the nucleus
A
- contains introns and exons
(introns don’t code for amino acids) - longer
(carries more genes) - linear
- DNA is wrapped around histones
4
Q
what type of molecule is DNA a polymer of
A
nucleotides
(due to it being a polynucleotide)
5
Q
list 4 characteristics of the DNA in prokaryotic cells
A
- shorter
- circular
- not in a nucleus
- not associated with histones
6
Q
when linear DNA is associated with a histone
what does it form?
A
chromosome
