BANANA DNA

Due next friday

How does the structure of DNA allow it to be so well suited to carrying inheritable information?

can be presented in anyway

DNA Replications

Alleles are created by mutations and replication errors, they can be neutral eg. left handed, positive eg. faster, or negative eg. no head.

Helicase undos (unzips) the DNA double helix and DNA prylimaries build two new double helixes using the two halves of the original. Proteins then attach themselves to the structure and bind it all together.

Summary: DNA replications is the first place mutation occurs. Mutations can the produce new alleles

Essay structure

S  - statement

E - explain

E – evidence/examples

D – discuss –other points of view and contrary evidence, 2 paragraphs

Chromosomes

the number of chromosomes in a animal doesn't mean anything in terms of intelligence etc. but is just the way the animals DNA is structured

Chromosomes 

DNA - holds genes, inheritable information

proteins - help in DNA replication 

homologous pairs - out of the chromosomes, have the same sequence of genes but can have different alleles, in that case the dominant allele shows in the organism 

usually chromosomes cant been seen but just before cell division they thicken up and can be seen and paired

sometimes during chromosomes copying (cell dividing) DNA can be changed, forming a mutation

mutations can have a  negative, positive or neutral effect on the organisim

just whatever
