Biology 10 Notes on DNA and Molecular Biology.

         deoxyribonucleic acid & ampere; Molecular Biology         DNA: figure of speech curlicue molecule that is blueprint for al close to every(prenominal) st on the whole or being on the planet. Deoxyribonucleic acids structure was sight by Watson & Crick in 1953.         Chromosome: coiled duration of DNA seen during cadre division that not during interphase. Chromosome attaches to mandrel fibres at the centromere in prophase.         Allele: Specific form of gene or function sequence of DNA. Version may be dominion (which is most viridity in gene pool), or any mavin of umpteen visibly (measurably) different sportswoman versions         homologous Chromosomes: 1 of 2 just about 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 monoploid (gamete) state.         Ploidy return: 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 just about every cell of the clay except the gametes which be haploid (monoploid). Most organisms are diploid, but some species are polyploidy (Chinook chromatic 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.         separatism of Genes: stern for meiosis which occurs in anaphase 1 when chromosomes are pulled unconnected without centromeres splitting. This military operation virtually guarantees gametes will be of many different genetic gains.         Phenotype: Phys ical appearance of a cell or organism as con! trolled by the genetic make-up (genotype). Most common appearance is usually termed wild type (normal), while slight common appearances are seen as mutant.         Genotype: Description of diametrical alleles for any gene. usher out be heterozygous, homozygous or hemizygous.         Dominance: Condition in...
