1). Explain why the segregation of homologous chromosomes in meiosis I leads to reduction in ploidy 2). Explain why no 2 haploid cells that result are alike in terms of genotype and why that is important for fitness 3). Given a micrograph, explain what is currently happening to the chromosomes 4). Recognize the cumulative nature of science by explaining the various contributions that led to the discovery of the structure of DNA 5). Explain the experimental designs and draw conclusions on the nat

1). Compare structure, chemical composition, location, and function of DNA with RNA 2). Define complementary base pairing and explain connection to antiparallel nature 3). Use pairing rules to explain proportionality of DNA bases, predict the sequence of a complementary strand of DNA, and calculate the percentage of each base in a DNA molecule when given the percentage of one base 4). Use a drawing to explain how a newly synthesized DNA strand is half old and half new 5). Label the origin of rep

1). Label template and coding strands, initiation complex, promoter site, RNA polymerase, ribonucleotides, the direction of RNA polymerase and direction of RNA synthesis in diagram of transcription initiation 2). Describes roles and positions in a prokaryotic gene or promoter and transcription initiation and termination site 3). Describe roles and positions in a eukaryotic gene of core promoter, transcription initiation and termination sites, introns, and exons 4). Identify which strand serves a
