Sequence Possibilities

A

4 to the power of the sequence length

17
Q

Human Genome

A

2.9 billion base pair long

18
Q

DNA is stable

A

DNA is stable

19
Q

Helical/Coiled

A

gives compact shape

20
Q

Long/Large molecule

A

Stores large amount of information

21
Q

Sugar-Phosphate backbone

A

gives strength to strands

22
Q

Double stranded with hydrogen bonds in the middle

A

protects hydrogen bonds and makes molecule stable

23
Q

Sequence of bases

A

allows information to be stored

24
Q

Complemtary base pairing

A

enables information to be replicated/transcribed

25
Q

Hydrogen bonding

A

allows chains to be split for replication/transcription

molecule unzips easily

26
Q

Many Hydrogen bonds

A

together give molecule stability

weak by themselves but strong in numbers

27
Q

DNA Replication

A

DNA Helicase unwinds the double helix
Hydrogen bonds between base pairs are broken
Free nuclotides bind with exposed complemetary bases forming hydrogen bonds
A to T and G to C
DNA Polymerase forms phosphodiester bonds between the phosphate group on one nucleotide and the sugar on another nucleotide
This continues all the way down the DNA molecule until an exact replica of the Dna molecules has been made

28
Q

Semi Conservative Replication

A

one of the 2 strands of the double helix is old and original while the other is newly synthesised
one parent and one new starnd

29
Q

Direction of DNA synthesis

A

5’ to 3’
one direction
stands are anti parallel so it looks like they are opposite but the are not
