Biology 10 Notes on DNA and Molecular Biology.

         deoxyribonucleic acid & ampere; Molecular Biology         DNA: prototype curlicue molecule that is blueprint for al close to every(prenominal) st both or being on the planet. Deoxyribonucleic acids structure was discovered by Watson & Crick in 1953.         Chromosome: coiled distance of DNA seen during cadre division just now not during interphase. Chromosome attaches to spindle fibres at the centromere in prophase.         Allele: Specific fluctuation of gene or function sequence of DNA. Version whitethorn be dominion (which is most viridity in gene pool), or any mavin of galore(postnominal) visibly (measurably) different variation versions         homologous Chromosomes: 1 of 2 around 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 haploid (gamete) st ate.         Ploidy pattern: number of contend sets of chromosomes in a carrell which contains all necessary genes for normal development, growth, and function. Note: Diploid (2n) has sets of chromosomes in approximately 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.

         separationism 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 conciliates.         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 slight common appearances are seen as mutant.         Genotype: Description of mated alleles for any gene. usher out be heterozygous, homozygous or hemizygous.         Dominance: Condition in...
