a very boring diagram on DNA/inheritance
inheratance
allele are variants of the same gene which affect hair and eye colour.
Bb would be B(black) and b(brown) capital is the dominant gene
children receive half of their chromosomes from each parents gametes which fuse
BB would be dominant and bb would be recessive
the human body normally has 46 chromosomes with 23 pairs.
mutation
some mutations alter the amino acids causing the protein to deform and cant carry out its function
the protein could be altered into a more efficient enzyme
most mutations have no effect and still allow the protein to fold into shape.
3 types of mutation/substitution,insertion,deletion
however it could deform and wont allow the enzyme to carry out its function
genome
HGP was started at the end of the last century and was hoping to be used to find flaws in peoples DNA that could cause health issues,
the genome is the entire genetic material of a person
nucleus/ centre of the cell and it stores all genetic information
DNA structure
makes up our genes with the 4 different bases which are called /thymine/guanine/cytosine and adenine
DNA is made up of 1 base/phosphate/and 1 sugar
stands for deoxyribose nucleic acid
the base makes up the backbone of the DNA and alows it to form the double helix shape
thymine goes to adenine/guanine goes to cytosine
