Interspecific Variation
Variation between different species
1 of 14
Intraspecific Variation
Variation between the same species
2 of 14
Random Sampling
Random Numer Generator and a statistical test
3 of 14
Standard Deviation
Spread of data around the mean
4 of 14
Nucleotide
Pentose sugar, phosphate group and base
5 of 14
ATCG
Adenine, thymine,cytosine,guanine
6 of 14
Structure of DNA
Nucleotides join to form a polynucleotide strand, bond between the phosphate of one and the sugar of another
7 of 14
Advantages of DNA structure
Fit a lot of genetic information in a small space-tightly coiled, double helix is more stable
8 of 14
DNA in Eukaryotics
DNA stored in chromosomes coiled and wrapped around proteins
9 of 14
DNA in prokaryotics
Chromosomes supercoiled
10 of 14
Gene
Section of DNA found on chromosomes, codes for proteins, ocupies a fixed position- locus on DNA
11 of 14
Protein Formation
Order of basew on DNA depends on which amino acids are ceated to make proteins
12 of 14
Introns
Sections of DNA which don't code for amino acids
13 of 14
Alleles
Different form of a gene, order of bases in each allele is slightly different, so they form sligtly different versions of the same characteristic
