double stranded DNA ¡VdsDNA). The DNA of the phage contains around 50‚000 base pairs and codes for 50 proteins. At both ends of the DNA of the phage‚ there are cohesive ends‚ which are composed of 12 nucleotides. Both ends compliment each other‚ which makes the DNA circular once together. This circular DNA is usually present in an infected bacterial cell. This protects the DNA to be degraded by the cell. In this laboratory experiment‚ restriction enzymes were used to analyze the DNA of the lambda

AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

Life Science Lab. A. Arnold Tuesdays @ 2:30 September 30th‚ 2011 Lab Report: Nuclear and Cell Division. PART A: Stages of Mitosis in my own words. 1. Interphase: DNA has formed already‚ but it remains in the simple form of chromatin. Chromatins are structures that are loosely coiled in the cell.3 I also observed during my lab that this was the only stage where I could still see a nucleus and nucleolus intact within the cell; this is because it’s the only stage where the nuclear membrane has

The purpose of this experiment was to acquaint the students with basic laboratory procedures‚ methods‚ and techniques; to introduce the use of basic laboratory measuring devices; to demonstrate different methods of manipulation of numerical quantities. DENSITY AND SPECIFIC GRAVITY Materials and Methods Part 1: Density of an Unknown Solid 1. We first were asked from our laboratory instructor to attain an unknown solid and were asked to note down the number of the solid. 2. Determine

Lactate Dehydrogenase (LDH) is an cytosolic enzyme that participates in anaerobic glycolysis. LDH couples the reduction of pyruvate into lactic acid to the oxidation of NADH to NAD+‚ which allows glycolysis to continue to produce ATP in the absence of oxygen. LDH is a tetramer‚ a protein complex of 4 polypeptide subunits‚ composed either a subunit expressed strongly in the heart‚ H type‚or a subunit that is highly expressed in the muscle‚ M type. There are 5 isozymes of LDH composed the 2 subunit

Biology Lab Scientific Paper Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms during pregnancy and how the baby’s body functions as it grows in the womb and after birth. Usually‚ a baby is born with 46 chromosomes but babies with Down syndrome have an extra copy of one of these chromosomes‚ chromosome 21. A medical term for having an extra copy of a chromosome is trisomy. Down syndrome
