The type of cell division that is represented in the figure and the relationship between the parts of figure. Introduction: Meiosis, also known as the reductional division, is the second type of cell division that takes place in eukaryotes. The cell division is marked by a decrease in the chromosome number to half. This type of cell division allows the recombination of the genes on the chromosome to produce a zygote. The two diploid cells undergo division to produce four haploid daughter cells.

Summary Introduction

To determine:

The difference between cohesion of centromeres and cohesion of arms.

Introduction:

The chromosomes are condensed structures that are formed during the early phases of cell division from the loose network of chromatin thread and then regain their original structure after being divided into daughter cells.

Summary Introduction

To determine:

The mechanism that keeps the chromosomes together during metaphase.

Introduction:

The human consists of 23 pairs of chromosomes, condensed form of chromatids which divide during cell division into daughter cells. The human has 22 autosomes and one pair of sex chromosomes. The sex chromosomes determine the sex in an individual based on the type of sex chromosomes that are present in the fusing gametes.

Summary Introduction

To determine:

The role of shugoshin and the enzyme it inhibits.

Introduction:

The chromosome from chromatids are formed through the process of supercoiling. The chromatin fibres are condensed into thick structures called the chromosomes. This chromosome in bacteria is circular whereas in eukaryotes it is linear.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
