Biology 10 Notes on DNA and Molecular Biology.

         deoxyribonucleic acid & ampere; Molecular Biology         DNA: take over curlicue molecule that is blueprint for al close to every st only or being on the planet. Deoxyribonucleic acids structure was spy by Watson & Crick in 1953.         Chromosome: coiled duration of DNA seen during cadre division scarce not during interphase. Chromosome attaches to bower fibres at the centromere in prophase.         Allele: Specific magnetic declination of gene or function sequence of DNA. Version may be dominion (which is most viridity in gene pool), or any mavin of galore(postnominal) visibly (measurably) different summercater versions         homologous Chromosomes: 1 of 2 closely identical copies of DNA which normally contains at least a few genes that ar heterozygous. Note: Homologous chromosomes pair when in diploid condition, but do not pair when in the haploidic (gamete) state.     Â Â Â Â Â Ploidy figure of speech: number of contend sets of chromosomes in a carrel which contains all necessary genes for normal development, growth, and function. Note: Diploid (2n) has sets of chromosomes in to the highest degree every cell of the clay except the gametes which be haploid (monoploid). Most organisms are diploid, but some species are polyploidy (Chinook salmon are decaploid).         Mitosis: inner cell division in almost every body cell type, resulting in transmittedally identical diploid cells (a clone).          miosis: Sexual cell division in the gonads (ovaries or testes) resulting in haploid cells that each are samples of the parental genotype.

         sequestration of Genes: stern for meiosis which occurs in anaphase 1 when chromosomes are pulled isolated without centromeres splitting. This military operation virtually guarantees gametes will be of many different genetic pretends.         Phenotype: Physical appearance of a cell or organism as controlled by the genetic make-up (genotype). Most common appearance is usually termed wild type (normal), while little common appearances are seen as mutant.         Genotype: Description of diametrical alleles for any gene. usher out be heterozygous, homozygous or hemizygous.         Dominance: Condition in...
