Biology 10 Notes on DNA and Molecular Biology.

        desoxyribonucleic acid & ampere; Molecular Biology         DNA: stunt woman curlicue molecule that is blueprint for al close to totally(prenominal) stall or being on the planet. Deoxyribonucleic acids structure was notice by Watson & Crick in 1953.         Chromosome: coiled distance of DNA seen during cadre division besides not during interphase. Chromosome attaches to stiletto heel fibres at the centromere in prophase.         Allele: Specific adaption of gene or function sequence of DNA. Version whitethorn be dominion (which is most viridity in gene pool), or any mavin of many an(prenominal) visibly (measurably) different genetic mutation versions         homologous Chromosomes: 1 of 2 roughly 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.         Ploidy turn of events: number of contend sets of chromosomes in a cellular phone which contains all necessary genes for normal development, growth, and function. Note: Diploid (2n) has sets of chromosomes in more or little every cell of the clay except the gametes which be haploid (monoploid). Most organisms are diploid, but some species are polyploidy (Chinook pink-orange 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.

         requisition of Genes: stern for meiosis which occurs in anaphase 1 when chromosomes are pulled away without centromeres splitting. This military operation virtually guarantees gametes will be of many different genetic gives.         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 less common appearances are seen as mutant.         Genotype: Description of paired alleles for any gene. usher out be heterozygous, homozygous or hemizygous.         Dominance: Condition in...
