Hershey & Chase experiment Experiment target: T2 Bacteriophage (a kind of virus, containing DNA and a protein coat) & E.Coli bacteria How does virus work? • Virus injects their genetic material into cell • Non-genetic part of the virus (protein coat) remains outside the cell • Infected cell produces large amount of viruses based on the genetic material in the cell • The cell bursts releasing copied viruses Experimental methodology: • Amino acid containing radioactive isotopes ...

INSTRUCTIONS: The following selections relate to distinguishing arguments from nonarguments and identifying conclusions. Select the best answer for each. 1. Incandescent light bulbs eventually burn out because the high temperature of the filament causes tungsten atoms to fly off and collect on the inside of the bulb's glass. This loss of tungsten is slowed, but not prevented, by introducing argon inside the bulb's envelope. As more and more atoms are lost, the filament disintegrates. When t...

Question bank from past papers for chapter 2,4,6,11 Questions and Answers (mark scheme)

This document explains in proteins in great detail, which may be simple but is a very complicated concept. The document includes class notes in black and syllabus notes in red. There are also links to past papers and practice questions. The SL and HL topics are both there. I recommend reading over the paper before an exam for revising.
