Week 1 – HOW LIFE WORKS: Biology – Science of How Life Works; study of life; attempt to understand processes of life. How life works - many levels. Three levels: -Molecular mechanisms within the cell -Integrated actions of many cells within an organ or body -Interactions among different organisms in nature Life Processes – Microscopic and macroscopic levels: All methods of scientific study use the Scientific Method Scientific Method –

some valuable information to me and also gave me some priceless advice. She told me that my ex told her that she really wasn’t sure who her child’s father was. The mutual friend then told to that it would be in my best interest to get a DNA test done. Having a DNA test performed leads me to the other step that I used which is step 4: Confirm All Key Findings. After having that conversation with this mutual friend, I made up my mind to have a

1. There is an inverse relationship between the total magnification and the diameter of the field of view. As magnification increases, the field of view decreases as seen in the calculations. 2. About 1 micrometer as seen from the drawing of the bacteria and averaging their sizes 3. 143 micrometers as seen from the drawings of the eukaryotes and averaging them. Eukaryotic cells are not all the same size as seen by comparing the size of the cheek cell to the size of a fungi cell. This can

Using Plasmid DNA pGLO To Trigger Resistance To Ampicillin. Author: Nick Delagarza Section: Tuesday 11:30, Room 121 TA: Huy D. Vu ABSTRACT – Transformation is the uptake of naked DNA in the environment by a recipient bacterium. The purpose of this experiment is to perform genetic transformations of E. Coli bacteria using plasmid DNA in forming resistance to Ampicillin. Escherichia coli is a bacterium is found in the human colon and in many areas of the environment. The Foreign DNA used in this

DNA Introduction Large pieces of DNA can be broken up into smaller fragments by bacterial enzymes known as restriction endonucleases (RE). They bind to specific nucleotide sequences within DNA, known as recognition sequences/sites and cleave the phosphate backbone at a point within this sequence. ------------------------------------------------- The recognition sequences are usually fairly short (4-8 base pairs) and have two characteristics: 1) They are PALINDROMIC i.e. the sequence on one of the

ASSIGNMENT 1: PROPERTIES OF DNA/RNA Introduction: The polymerase chain reaction is an innovative technology, which amplifies a single piece of DNA across several orders of magnitude. The end result is the creation of thousands to millions of copies of a particular DNA sequence. PCR is closely patterned after the natural principle of DNA replication. It is a three-step process, referred to as a cycle, that is repeated a specified number of times. One PCR cycle consists of the following steps:

the interior of the cell by allowing some substances into the cell, and also blocking some substances from coming in. Main functions of the nucleus The nucleus is the centre of the cell which controls things. Nuclei contains genetic material e.g. DNA and also controls the cells growth and reproduction. In red blood cells, the nucleus is lost during development and is the only cell that is able to survive without a nucleus. The nucleus contains information that is transferred to the next generation

before birth. In cells, this protein is involved in transporting materials, chemical signaling, binding to proteins, and protects the cells from self-destruction. The coding area of the gene contains the DNA sequence repeated many times. People infected with Huntington disease have a high number of the DNA which disrupts the working of the gene protein (Quarrell, 2008). The disease is inherited in an autosomal pattern, meaning those inheriting the faulty gene will get the disease. Results of the findings
