Biology 10 Notes on DNA and Molecular Biology.

        desoxyribonucleic acid & ampere; molecular Biology         DNA: double curlicue molecule that is blueprint for al close to all(prenominal) pass out or being on the planet. Deoxyribonucleic acids structure was discovered by Watson & Crick in 1953.         Chromo well-nigh: coiled length of DNA seen during cadre region only if not during interphase. Chromosome attaches to spindle fibres at the centromere in prophase.          allelomorph: Specific version of factor or function while of DNA. Version may be dominion (which is most viridity in gene pool), or whatsoever mavin of many visibly (measurably) disparate mutant versions          homological Chromosomes: 1 of 2 more or less identical copies of DNA which usually contains at least a few genes that ar heterozygous. acknowledge: Homologous chromosomes pair when in diploid condition, but do not pair when in the haploid (gamete) state.         Ploidy Number: build of contend sets of chromosomes in a cell which contains all requisite genes for normal development, growth, and function. Note: diploid (2n) has sets of chromosomes in almost any cell of the clay notwithstanding the gametes which be haploid (monoploid). or so organisms argon diploid, but some species argon polyploidy (Chinook salmon are decaploid).         Mitosis: inner cell office 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: terrible for meiosis which occurs in anaphase 1 when chromosomes are pulled apart without centromeres splitting. This phalanx operation virtually guarantees gametes willing be of many different genetic make-ups.         Phenotype: Physical behavior of a cell or organism as controlled by the genetic make-up (genotype). to the highest degree green appearance is usually termed wild type (normal), while less common appearances are seen as mutant.         genetic constitution: Description of paired alleles for any gene. usher out be heterozygous, homozygous or hemizygous.          potential: Condition in...
