ANATOMY AND PHYSIOLOGY TEST 1/2/3/4/5/6/7 QUESTIONS AND ANSWERS LATEST UPDATED 2023. How can such a weak bond like hydrogen bond work to make DNA such a stable molecule? - ANSWER hydrogen bonds bond DNA into its double-helix structure by holding together the base pairs in the middle; they cause molecules to fold and coil into precise threedimensional shapes which elements are found in organic molecules? - ANSWER carbon, hydrogen, and oxygen acid - ANSWER proton donor base - ANSWER proton ac...

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...

What are the properties of a eukaryotic cell - • Well define nucleus. • cells are larger and have more extensive intracellular anatomy and organization than do prokaryotes. • cells bind with deoxyribonucleic acid (DNA) and are involved in the super coiling of DNA. • cells have several chromosomes, protein production or synthesis . it consists of three components: outer membrane called plasma membrane, a fluid filling called cytoplasm, and the intra cellular organs or organelles ...
