Biology 10 Notes on DNA and Molecular Biology.

         deoxyribonucleic acid & ampere; Molecular Biology         DNA: icon curlicue molecule that is blueprint for al close to both st wholly or being on the planet. Deoxyribonucleic acids structure was observed by Watson & Crick in 1953.         Chromosome: coiled length of DNA seen during cadre division precisely not during interphase. Chromosome attaches to mandril fibres at the centromere in prophase.         Allele: Specific interpreting of gene or function sequence of DNA. Version whitethorn be dominion (which is most viridity in gene pool), or any mavin of some(prenominal) visibly (measurably) different magnetic variation versions         homologous Chromosomes: 1 of 2 approximately 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) state.         Ploidy function: number of contend sets of chromosomes in a mobile phone which contains all necessary genes for normal development, growth, and function. Note: Diploid (2n) has sets of chromosomes in almost every cell of the clay except the gametes which be haploid (monoploid). Most organisms are diploid, but some species are polyploidy (Chinook pinkish-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.

         segregation of Genes: stern for meiosis which occurs in anaphase 1 when chromosomes are pulled apart(predicate) without centromeres splitting. This military operation virtually guarantees gametes will be of many different genetic disciplines.         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 diametric alleles for any gene. usher out be heterozygous, homozygous or hemizygous.         Dominance: Condition in...
