Document Summary
Dna: a(cid:374)tipa(cid:396)allel (cid:894)(cid:1009)" (cid:1007)" a(cid:271)o(cid:448)e (cid:1007)" (cid:1009)"(cid:895, double-stranded helix, made of nucleotides (a,t,c,g) (cid:272)ha(cid:396)gaff"s la(cid:449): a-t. c-g. Monomer: nucleotide consisting of a sugar (deoxyribose, bonded to a phosphate, also bonded to either a,t,c, or g. Central dogma: dna rna protein, proteins are the end product of gene expression, protein action or location in a cell produces phenotype(s, 20 different amino acid building blocks. Need to replicate dna with each cell division. Mitosis: occurs in embryo and during organ development in adults happens in renewable tissues that have stem cells. Binomial theorem: 2 alternative outcomes, probability based on # of trials, p=(n!/s!t)*(a^s*b^t) p=probability n=# of trials a=probability of event a b=probability of event b s=# of times of outcome a t=# of times of outcome b. Incomplete dominance- neither allele is dominant and an intermediate phenotype is present for heterozygotes. Codominance- both alleles are dominant, and both traits will appear in the heterozygote organism (like in human blood types a,b,o)
