Nucleus - Answer- a part of the cell containing DNA and RNA and responsible for growth and reproduction. DNA - Answer- a long linear polymer, in nucleus, formed from nucleotides and shaped like a double helix, contains info that determines inherited characteristics RNA - Answer- a long linear polymer of nucleotides, in nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes, ribonucleic acid; a nucleic acid that plays an important role in the production of prot...

Cell Theory - ANSWER-Discovered in the 17th century 1. All living things are composed of cells 2. The cell is the basic unit of life 3. The chemical reactions of life take place inside the cell 4. Cells arise from only preexisting cells 5. Cells carry genetic information in the form of DNA. This genetic material is passed from parent cell to daughter cell 6 Kingdoms - ANSWER-Bacteria, Archaea, Protista, Fungi, Plantae, and Animalia Prokaryotic - ANSWER-"before nucleus", lacks a memb...

Pre-Lab Questions 1. What are chromosomes made of? Chromosomes are structures composed of DNA and proteins known as chromatin. Within chromatin, there is a component called a nucleosome. 2. Compare and contrast mitosis and meiosis. Both meiosis and mitosis start with only two chromosomes and involve the creation of new cells. However, meiosis does not involve crossing over and synapsis, whereas mitosis, which occurs in somatic cells, does. Mitosis produces body cells, while meiosis produc...
