Thank you for your input. Problem Test handedness in various people.

Laboratory left handedness and experiment

Following incubation, obtain your four micro test tubes L, P, E, and H and place them in the foam micro test tube holder at your laboratory desk. Set the digital micropipet to 2. Use a fresh tip with each sample to avoid contamination.

The DNA samples and the sample loading dye must be thoroughly mixed in each tube before placing the samples in the gel wells for electrophoresis. This is easily accomplished by holding the top of a microtube between the index finger and thumb of one hand and flicking the bottom of the tube gently with the index finger of the other hand.

Obtain the DNA marker M from your teacher. Set up Electrophoresis Chamber 1. Obtain an agarose gel from your teacher, or, if your teacher instructs you to do so, pour your own gel.

Place the casting tray, with the solidified gel in it, onto the central platform in the gel box. The wells should be at the negative cathode end of the box where the black electrical lead is connected.

Very carefully remove the comb from the gel by gently pulling it straight up.

Pour about ml of electrophoresis buffer into the electrophoresis chamber. Pour enough buffer into the box until it just covers the wells of the gel by 1—2 mm. Load and Run the Samples by Electrophoresis 1. Use a fresh tip for each tube. Gels are read from left to right.

To keep things straight, the first sample is typically loaded in the well at the upper left-hand corner of the gel. Slide the cover of the chamber into place, and connect electrical leads to the power supply, anode to anode red to red and cathode to cathode black to black.

Make sure both electrical leads are attached to the same channel of the power supply. Electrophorese at V for 30—40 minutes.

Shortly after the current is applied, the loading dye can be seen moving through the gel toward the positive side of the gel chamber 4.

When electrophoresis is complete, turn off the power supply, disconnect the leads from the inputs, and remove the top of gel chamber.

Remove the casting tray from gel chamber. Record your data and analyze results.Topics: Handedness, Right-handedness, Left-handedness Pages: 2 ( words) Published: November 2, Title: Study of Dominant Thumb and Handedness Abstract: In this experiment, the relationship of handedness and thumb dominance was tested.

Wu experiment - Wikipedia Monday, 13 February This handedness crops up nearly everywhere in nature, from galaxy spirals down to the quantum mechanical properties of fundamental particles.

50 people were asked to clasp their hands. Handedness and individual differences. Left-handers are thought to possess a number of special cognitive abilities: some of them good, some bad. The streak plate method is a rapid qualitative isolation method for obtaining discrete colonies from a mixed population.

Lift the test tube containing the inoculum with your left hand. Switch off the laminar air flow and exhaust fans before leaving the laboratory.

Ensure proper hand washing before you leave from the laboratory.
