what is dna
-chemical that all genetic material in a cell is made up from -complex molecule that carries information
what 2 things does you dna determine
-your inherited characteristics -what protein the cell produces(haemoglobin, keratin)
what is dna made up of  
polymer(long chain of similar molecules)of nucleotides
what are the 4 types of nucleotides  
A, C, T, G
what do two chains of nucleotides wrapped around each other make
double helix-A with T & G with C
where is dna found in animal and plant cells and what is it in  
-found in the nucleus in long structure called chromosomes which are packaged by protein
-chromosomes are usually found in pairs
what is a gene  
small section of dna found on a chromosome
what does each gene contain the instructions for
particular sequence of amino acids which are put together to make specific protein
what is a genome  
entire sequence of nucleotides in all genes in an organism
why are the three reasons it is important that scientists understand the human genome  
to understand which genes are linked to inherited disorders
identify genes in the genome that are linked to disease
to trace migration patterns
