Document Summary
In this lecture, we"ll talk in greater detail about dna structure, 1313 about the arrangement of dna into a double helix, the organization of dna into chromosomes, 1314 and the way that genes are arranged on chromosomes. 1315 [00:00:17. 67] in dna, there are 3 basic parts, as we"ve seen before. 1316 a sugar group-- these two will combine to form the backbone-- and a base, which will encode the. 1317 information in the center of the strand. Together, these 3 pieces are called a nucleotide. 1318 nucleotides will join together to form a linear sequence of bases which can be read out by. 1320 [00:00:49. 34] it"s called a double helix because there are two strands in dna that base pair with. You have one strand on this side and a second strand going this side. 1322 are anti-parallel that means that the directionality is different. You have a 5 " end running to a 3 "
