Eukaryotic Chromosomes - ️️The multiple linear chromosomes in a eukaryotic nucleus are highly condensed Degree of coiling and packing changes throughout cell cycle Interphase: relatively more relaxed = less condensed Mitotic phase: relatively more compact = fully condensed for movement of individual chromosomes during cell division Genome size - ️️The genomes of different species contain different amounts of DNA. The complexity of an organism doesn't necessarily match the amou...

Lab Report Format Expectations Utilize college level grammar and professional formatting when completing this worksheet. Pre-Lab Questions 1. Identify two differences between the composition of DNA and RNA. DNA takes the form of a double helix and is often described as looking like a long, twisted ladder with rungs. RNA is single stranded and shorter than DNA . It can fold back on itself due to hydrogen bonding to form a stem loop structure. 2. Suppose you are performing an experiment in ...
