Genetics

Mrs. Sidelsky

General Format. A laboratory report is an organized account of an experiment.  it must be done on a word processor.  No hand-written laboratory reports will be accepted.The language should not be personalized. It should contain accurate scientific language and terminology..

Each laboratory report should have a cover sheet or title page with the following information

Your name (lower right hand corner)

Laboratory Partner or Group

Period

Date

This page may be custom made to the experiment.  Cover Page will be considered for bonus points if it shows creativity in design and content.

2. Problem or Question that you are investigating or studying. The problem should be clearly defined in a well-written sentence.

How can different forms of hemoglobin be identified in a protein gel?

How can agarose gel electrophoresis be used to separate different sizes of DNA fragments?

How will the genotypic and phenotypic ratios of linked and non linked genes differ in Drosophila melanogaster ?

4.Introduction. The introduction should be a description of the scientific basis or premise for the experiment. It should include a definition of important terms. It may also include recent research, which is related to the experiment.

5.Materials and Methods.

1. Materials. List the materials in an orderly manner. Diagrams are essential to Genetics experiments. Include diagrams of experimental organisms, techniques, and instruments.

b. Method. (s) List the steps in the procedure of your experiment. State clearly in phrases or complete sentences. This should also describe the use of specialized instruments. In the case of more advanced experimental procedures this is referred to as a protocol.

Outline the steps in the experiment, which you are undertaking.

Identify the constants and controls.

5. Results (Data)

Qualitative observations may be written in a paragraph. These may also be organized in a chart.

Nominal observations- Descriptions. These include photographs of experimental results with an explanation.

Ordinal observations- descriptive observations written on a scale from 0 to + 5

Quantitative observations. This is data that is measured carefully. Units of measurement in science are based on the Metric system. In Genetics this may also be for

Size of proteins- kilodaltons ( a dalton = 1 amu )

Size of DNA- kilobases or base pairs

Arrange this data in a chart. Independent variable(s) and Dependent variable(s)

Provide a graph of your data. If there is a relationship between the independent and dependent variable use a linear graph.

Bar graphs and pie graphs may also be used to describe experimental results.

******* Number diagrams as figures( fig.1)

Number charts as tables

7. For future study or research. If you were to continue the study of this problem how would you continue?
