Which step in the PCR program would you have to change if your fragment would have been 10 times longer and how?
bekas [8.4K]

Answer:

increasing extension time

Explanation:

The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.

Heart rate decreased suddenly and then MAP immediately fell because peripheral blood vessels were extensively vasodilated.

Explanation:

A VO2 max test is a clinical test done in a lab and is the ‘golden standard’ for measuring the potential and cardio-respiratory endurance of athletes and bikers.

It measures the oxygen carrying capability through a graded step test which determines the average power output. The maximal oxygen uptake along with cardiorespiratory responses is measured.

As per exercise physiology, the heart rate and cardiac output increases with exercise. When the potential is less, the resistance decreases, heart rate and mean arterial pressure also decrease .

After performing a gram stain of a mixed culture of gram positive and gram negative cells, you shout: "oops, i forgot the iodine
zalisa [80]

Gram's staining is a differential staining technique that employs a primary stain like crystal violet and a counter stain like safranin along with the decolourizing agent alcohol and a mordant called the Gram's iodine.

Iodine is a mordant added after the primary stain. It fixes the stain by combining with it to enchance the staining ability. This forms an insoluble crystal violet iodine complex appearing purple under the microscope. These microorganisms are classified as Gram positive.

If addition of iodine is skipped, crystal violet is not fixed on the slide and the insoluble complex is not formed. The cells are decolourized by alcohol and are stained by the counter stain safranin making the Gram positive cells wrongly indentified as Gram negative due to its pink colouration. Thus, the slide will show all the cells as pink coloured Gram negative cells.
