pluripotent stem (IPS) cells differ from those currently in place for human embryonic stem (ES) cells. An IPS cell is created artificially from skin‚ fat and fibroblasts by reprogramming patient ’s own cells. Scientists believe IPS cells to be a promising source for treating diseases. An ES cell is created by destroying an embryo. Other scientists think ES cells will also be a promising source because it is composed of your own DNA‚ so the immune system won ’t reject the cell. While scientists would

YOUR NOTES UNIT 2 NOTES DNA (deoxyribonucleic acid) DNA Functions • Stores genetic information and copies itself (replication) to pass on the information • Contains genes (instructions to make proteins) • Instructs cell’s activities DNA Structure • DNA is a polymer of nucleotides • Chromosomes (DNA strand + associated proteins ie. Histones wrap DNA around like a spool = condensed chromatin) ↓ genes (sections of a chromosome that codes for a protein) ↓ nucleotides (3 parts:

Decoding the DNA of the Toyota Production system: The Toyota Production system has long been considered as the source of Toyota’s outstanding performance as a manufacturer. The distinctive practices of the system especially Kanban and quality circles have been widely used elsewhere. Companies that have tried to adopt the Toyota Production System can be found in diverse fields. However‚ what is surprising is that only a few manufacturers have succeeded in imitating Toyota successfully even though

The Cell Cycle Brittany Jameson Vista College Abstract The cell cycle is made up of five steps. These steps are interphase‚ mitosis‚ cytoplasmic division‚ cell differentiation‚ and cell death. During mitosis there is a series of four stages. The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division

Cell Lab Report Experiments : 1. PCR . 2. Protein extraction and purification . 3. Protein concentration determination . 4. SDS-PAGE . 1. The aim of experiments : 2.1 The aim of PCR experiment is to replicate some DNA dimmers by using specific enzymes used for replication in vitro which is done in lab not by living organisms. 2.2 The aim of protein extraction and purification experiment is to extract some proteins and purify them by specific methods.

Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although they both contain ribosomes‚ they are composed differently. 3. The central vacuole (takes in water and chemicals)‚ cell wall (allows the plant to be strong enough

Animal Cells Vs. Plant Cells There are quite a few similarities and differences between plant and animal cells. Whether it be the internal parts of the cells‚ or the processes they go through. They also have differences in shape and sometimes size. These are only a few examples of similarities and differences between the two different cells. To begin with‚ both animal and plant cells are eukaryotic cells. This means that both cells have the same internal features‚ such as a cell membrane‚ a

Stem Cell Research: Should we continue to allow scientists to create new embryonic stem cell lines? Good morning everyone. The topic of Stem Cell Research has been argued over by politicians‚ scientists and people all over the world for over a decade. Scientists should not be allowed to continue to create new embryonic stem cell lines. One of the ways to obtain stem cells for scientific research is to destroy a blastocyst (laboratory-fertilized human egg). Destroying the blastocyst is the equivalent
