Essays on Interphase

There are six stages in the life cycle of a mitotic cell which include interphase and cytokinesis. The mitosis stage is divided into four other sub stages. Mr. Interphase performs various functions such as the cellular respiration, photosynthesis and protein synthesis in preparation to undergo the Mitosis stage. Mr. Mitosis has four witnesses, Prophase who helped nuclear membrane disappear into the genetic material. The other witness, Metaphase, makes the alignment of the chromosomes. Anaphase helps in centralizing the chromosomes and changing them from being x-shaped (Rieder, 17). The last witness created the new component of nuclei with their new ...

Q1. Explain the regulation of the cell cycle

Every cell is regulated by particular checkpoints to ensure that the daughter cells are exact duplications. This is to help guarantee that cell mutations are not passed on to the next generation of cells. In eukaryotic cells, there are three main checkpoints. These are points at which cell replication can be halted until certain conditions are met (Boundless, 2016). The first checkpoint is near the end of the G1 phase. It is here that DNA gets evaluated and checked for damage. If damage has occurred, it either gets corrected or gets prevented from moving on to the next phase ( ...

Article Review on Polytene Chromosomes and Structural Abnormalities

Background The interphase stage during cell division condenses the genetic material i.e. DNA into chromosomes and in salivary glands of Drosophila melanogaster, polytene chromosomes appear characteristically that are a result of repeated replication cycles but no disjunction. They have dark bands alternating with light interbands. The hypothesis tested in the research work performed by Zhimulev et al in 2014 was that the interbands incorporates transcripton initiation sites i.e. promoter binding areas that extend to coding areas in band regions. Using the modENCODE protein profiling data, DamID genome mapping has earlier classified various chromatin states. The current study performed cytological ...

Question 1

Binary mission in prokaryotes Mitosis and Meiosis in eukaryotes Question 2 The development of embryos as well as the growth and development of bodies. Important in asexual reproduction. Question 3 The term cell cycle refers to an ordered set of events leading to cell growth and division into two daughter cells.

Question 4

Interphase is a phase of the cell cycle characterized by the absence of cell division. During this phase, the cell obtain nutrients, the organelles duplicates, protein synthesis takes place, and cells duplicate its genetic material (its chromatids). The genetic material is located in the nuclei of ...

Introduction & Purpose

Typing is one of the essential skills that a white-collar or even a blue-collar employee should learn (David 2-5). An aerospace firm situated at the heart of Seattle, Washington is concerned about the keyboard typing skills of it’s over 2000 white-collar employees. Most of the tasks involved in the company require the use of a computer and other gadgets that utilizes a QWERTY pad. Mr. Underwood, the firm’s personnel manager, together with the director of training is planning to conduct a company-wide training program so that aims to enhance their slow and poor keyboard-typing skills.

In order to make the process of ...
