Unformatted text preview: hromosome look like? Chromosome: the organized double-stranded DNA molecules with its associated proteins and RNAs BIOLOGY 1A03 Cellular and Molecular Biology Scien6sts create “maps” of bacterial chromosomes. BIOLOGY 1A03 Cellular and Molecular Biology Genomic maps illustrate the position of genes on the prokaryotic chromosome. Also shown above: maps of circular plasmids Genes can be divided into func6onal categories BIOLOGY 1A03 Cellular and Molecular Biology This allows observation of genome content as fractions of the whole genome DNA molecules carry genes. How did scienAsts discover that DNA was the hereditary material of the cell? BIOLOGY 1A03 Cellular and Molecular Biology Unit 2: DNA as hereditary material There is hereditary informa6on in prokaryote cells. Frederick Griffith (1928) BIOLOGY 1A03 Cellular and Molecular Biology (polysaccharide coat on S strain) There is hereditary informa6on in prokaryote cells. 1 2 3 BIOLOGY 1A03 Cellular and Molecular Biology 4 There is hereditary informa6on in pro...
