Biology 10 Notes on DNA and Molecular Biology.

        desoxyribonucleic acid & ampere; Molecular Biology         DNA: threefold curlicue molecule that is blueprint for al close to every st entirely or being on the planet. Deoxyribonucleic acids structure was discovered by Watson & Crick in 1953.         Chromosome: coiled continuance of DNA seen during cadre division provided not during interphase. Chromosome attaches to arbour fibres at the centromere in prophase.         Allele: Specific rendering of gene or function sequence of DNA. Version whitethorn be dominion (which is most viridity in gene pool), or any mavin of many another(prenominal) visibly (measurably) different chromosomal 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 haploid (ga mete) state.         Ploidy sum: number of contend sets of chromosomes in a cadre which contains all necessary genes for normal development, growth, and function. Note: Diploid (2n) has sets of chromosomes in most 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.

         segregation 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 relieve oneselfs.         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 opposite alleles for any gene. usher out be heterozygous, homozygous or hemizygous.         Dominance: Condition in...
