Document Summary
Apply understanding of the characteristics/properties of dna and rna to different molecular/genetic techniques. Discuss how dna is packaged in chromosomes (in terms of histones, nucleosomes, and chromatin), and the lack of correlation between chromosome size and genetic information content. Describe characteristics of homologous chromosomes, including how the positions of individual genes on a given chromosome are related to their positions on the homologue of that chromosome (i. e. , the relative positions of a gene on homologous chromosomes). Describe dna replication using appropriate terminology and referencing appropriate components, relating dna replication to the formation of sister chromatids. Apply knowledge of dna replication (both in vivo and in vitro, i. e. , pcr) to molecular techniques used to study genetics. Explain the meaning of ploidy (e. g. , haploid, diploid), and how it relates to the number of homologues of each chromosome. Given a word problem or figure, determine (and explain) the ploidy of a given cell, distinguishing between sister chromatids and homologues.
