LIFSCI 7B XL - Animation: Meiotic Cell Division Copy Questions and Answers 100% Pass Question: What is the primary purpose of meiosis in cell biology? Answer: The primary purpose of meiosis is to produce gametes (sperm and eggs) with half the number of chromosomes as the parent cell, facilitating sexual reproduction and genetic diversity. Question: How many stages are there in meiosis, and what are they called? Answer: Meiosis consists of two main stages: Meiosis I and Meiosis II...

Sister chromatids are which of the following? a. Found right after a cell divides. b. Formed when chromatids separate during cell division. c. Unique to prokaryotes. d. Tightly linked together at a centromere. e. Made only of DNA - Answer-d. Tightly linked together at a centromere. Looking into your microscope, you spot an unusual cell. Instead of the typical rounded cell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you re...

What is the path of light through the compound microscope? - ANSWER Light source --> condenser --> specimen --> objective lens --> ocular lens The image from the objective lens is magnified again by the ocular lens. What are the steps of a gram-stain? - ANSWER 1) Primary stain (crystal violet) - 1 minute 2) Mordant (Gram's iodine) - 1 minute 3) Decolorizing agent (ethanol) - 5 seconds 4) Counterstain (safranin) - 1 minute *blot dry, not wipe What is this specimen? -...

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...
