The study of mitosis and meiosis-how scientists study it.

What are some of the methods that scientists have used to study the components, processes, and outcomes of cell division?

More questions--but easy.

For the first question, I thought PCR might have something to do with it, but it seems to restrictive. I can't think of any other descriptive techniques. can anyone suggest any? For question 2, it look simple but when a deletion occurs does it happen to the top and bottom strand? I was just wondering because that changes the whole complex of DNA. if it only happens in one strand then some strands will be shorter than others. 1. A biologist discovers an obscure bacterium with an enzyme that catalyzes the breakdown of a toxic byproduct of computer-chip manufacturing. It has real commercial potential, but it is made in very small quantities, and the bacterium cannot be grown very easily. ... click for more

The Relative Sizes of Cells, and Cellular Components

Various types of cells and cellular components are listed below. Based on the diameters of the cells and components (given in parentheses), calculate the number of each that you would expect to find in a single layer that is 0.7 mm in diameter. Assumption: each entity is spherical. Formulas: area of a circle = pi*r^2. pi=3.14 hepatocyte (d=20 micrometer) mitochondria (d=1.5 micrometer) actin molecule (d=3.6 nanometer)

Redox reactions in cell respiration

What are the two different redox reactions in cell respirations? Indicate which molecules if any have been oxidized and which have been reduced.

Understanding cell respiration, gylcolysis, krebs cycle, and the electron transport chain.

Cell respiration has three parts: glycolysis, the Krebs cycle, and the electron transport chain. Where in the cell is each found, the molecule(s) that enter each, the molecules at the end of each, and the number of ATPs harvested from each?
