Question
Chapter 11.5, Problem 1CS
Summary Introduction
To explain: The reason that it is necessary for the chromosomes to become highly compacted in preparation for cell division.
Introduction: Cell is the “basic unit” of life. Every organism is composed of a cell. Cell division is an important function performed by every cell to increase its populations and to survive. The process in which a single cell splits into two progeny cells is termed as cell division. Different organisms have a different mechanism for cell division such as binary fission, budding, mitosis, meiosis and so on.

This will represent the chromatin in a cell. The wires of the same length are homologous. Red wires will represent the chromatin from the female parent while green wires represent the chromatin from the male parent. Label the chromatin as follows: long green- 1a short green- 2c long red- 1b short red- 2d 2- Let the cell pass S phase. Replicate or duplicate each chromatin fiber. Do this by getting another set of wire identical to the original set. Label as before. 3- Combine the replicated chromatin fiber using masking tape. The tape will also mark the position of the centromere. For the short chromatin, place the tape exactly at the middle while for the long chromatin, place it at a point % from the end of the wire. 4- Assume that the chromosome fibers are folded.

- How to write the methodology? I have a practical of HOMOGENIZATION AND FREEZE-DRYING, I need to do a lab report, but I don't know how to write the methodology. Here is the introduction: HomogenizationHomogenization is a process that involves breaking apart cells to release theircytoplasm and its contents. When the purpose is to extract organelles, it is frequentlydone in two steps; first, using a blender to break the tissue up, and then with anultrasonic or mechanical tissue disruptor. The organelles are then generally separatedusing differential centrifugation.Freeze-dryingFreeze-drying also known as lyophilization, and it is a dehydration process typicallyused to preserve perishable material or make the material more convenient fortransport. It works by freezing the material and then reducing the surrounding pressureto allow the frozen water in the material to sublimate directly from the solid phase tothe gas phase.arrow_forwardLearning Task 2: Make a model of a DNA template to determine the sequence of bases in th new DNA strands. Then, answer the guide questions that follow. Materials: crayons. Scissors, paste/tape, used folder or illustration board Procedure: Use the pattern of the DNA template: (attached to this LP). Color code, phosphate - blue, deoxyribose sugar = green, nitrogenous base as follows: adenine= yellow, thymine pink, guanine = violet, cytosine = red. And cut the shapes of each nucleotides. Build a model of a strand of a DNA molecule. The strand should contain 6 base" rungs" following the given order of the nucleotides: Guanine, Adenine, Cytosine, Thymine, Cytosine, Guanine. %3D %3D Tape the cutout pattern to form the nucieotides.
