BiologyAll UnitsASAQA Created by: The ShrewCreated on: 24-05-15 11:33 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 14 of 14
