BSC 215 Spring 2014- Exam 2 Required Reading and Study Guide. The ‘required reading’ sections below include material that will be covered on exam 2. Here is an effective way to approach your required reading: BEFORE EACH CLASS: Read the assigned text for the chapter that is listed in the “required reading” Sections below. For this first read‚ it is not necessary that you attempt to understand everything in the required reading. It is more important that you read for the “big picture” concepts

Homologous Chromosomes and Sister Chromatids (HC and SC): Clearly distinguish between HC and SC pairs. Your answer should include the following: a clear distinction between ‘chromatin’ and ‘chromosome’‚ and how this difference affects gene expression; simple line diagrams to illustrate the difference between non-replicated and replicated DNA inchromatin and chromosome forms; afull description of both HC and SC with a labeled diagram that includes gene/allele sequences for a heterozygote and ‘m’

Cancer Assignment: Part A 1. Cancer is a group of diseases in which cells grows and divide out of control‚ it is caused by a change in DNA that controls the cell cycle. This DNA change causes for cells not to stay in interphase for the normal amount of time‚ and some of the checkpoints fail and cause the cells to divide uncontrollably. The uncontrollable division rate can create a massive group of cells called a tumour. The cells of the tumour may stay together and have no other effect on the tissues

PRACTICAL 3 QUESTIONS PART 1 Q 1. What is the diameter of the field of view of your microscope using the x10 objective (i.e. at a magnification of x100)? The diameter of the field of view using the x10 objective is 1800 µm. Q 2. What is the diameter of the field of view of your microscope using the x40 objective (i.e. at a magnification of x400)? The diameter of the field of view using the x40 objective is 400 µm. Q 3. What is the ratio of magnification between the x10 and x40 objectives?

Cell Cycle Definition- The process of the cell to divide into new cells. Interphase Description- the phase that occurs before cell division‚ the preparation for cell divisions Stages: G1- Rapid growth of the cell‚ metabolic activity. S- Synthesis‚ DNA replication. G2- Getting ready for cell division. Centrioles replicate Mitosis and Cell Division Function- To grow repair and maintain the cells in the body along with the reproduction of those cells. Results- Two identical daughter

There are hormones in the organism’s body that sends signals to the cells to prepare for division when it is needed.

Without mitosis and meiosis simple organism could not reproduce and complex organism could not repair
