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...

Cell Cycle An ordered sequence of events in the life of a cell Mitosis A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei. Cytokinesis The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II. Cell Division The reproduct...
