Document Summary
What is the structure of dna: nucleotide structure: 3 parts, phosphate group, pentose sugar, nitrogenous base (1of 4, the four nucleotides of dna (pg. The two dna strands run in opposite directions. 1,048,576: what is the compliment of this nucleotide strand, p-acgttcg-s, compliment is: p-tgcaagc-s, **** dna is used to make rna is used to make proteins***** How does dna replication ensure genetic constancy: dna replications (fig. 9-4: 1. separation of parental dna helix, 2. incorporation of complimentary nucleotides that were previously synthesized in the cytoplasm and imported into the nucleus, 3. a variety of enzymes that unwind the parental dna double helix and synthesize new. Dna strands: 2 daughter helices, 1 old strand, 1 new strand, the semiconservative replication model (pag. 209: chromosome-> one dna double helix, both strands of original dna serve as templates for the duplicated chromosome strands, duplicated chromosomes- sister chromosomes, daughter chromosomes half old, half new, replication bubble (fig.
