<Tab/>DNA & Molecular Biology <Tab/>DNA: double helix molecule that is blueprint for almost every cell or organism on the planet. Deoxyribonucleic acid's structure was discovered by Watson & Crick in 1953. <Tab/>Chromosome: coiled length of DNA seen during cell division but not during interphase. Chromosome attaches to spindle fibres at the centromere in prophase. &…showed first 75 words of 658 total…

Note: any DNA connected by a centromere is termed a chromosome; therefore, 2 sister chromatids = 1 chromosome. <Tab/>Linkage: Condition where 2 or more genes are located on the same chromosome and therefore segregate in anaphase 1 of meiosis as if they were attached to each other. Note: after Mendel's time, crossing over was discovered which showed that linkage is not permanent.
