(6 cards)
1
Q
How much DNA in metres do we inherit from our parents?
A
1 m
2
Q
How much of proteins are translated?
A
1-2 cm actually carries information that codes proteins
3
Q
How are nucleosomes formed?
A
- Cells were open with de-oxyribonuclease
- Cuts down into single nucleotides randomly
- DNA becomes smaller and smaller
- Bands form as DNA is wrapped around proteins called nucleosomes (evidence for DNA being wound up)
4
Q
What does the pattern of digestion indicate?
A
The pattern of digestion indicates that there is an irreducible minimum structural unit
5
Q
What is the nucleosome structure?
A
146 base pairs in 1.65 turns around histone core
6
Q
What are the nucleosomes interactions?
A
H2A, H2B, H3 & H4
