You have a DNA sequence that codes for a protein and is 105 nucleotides long.A frame shift mutation occurs at the 85th base how
Anna [14]
In a DNA molecule, three nucleotides make up a codon. A codon is creates a specific amino acid. Therefore, in order to work this out, we must calculate the number of codons that will not be affected by the mutation. This is done by finding the highest number that is divisible by 3 but less than 85. This can be done by:
85 / 3 = 28.333
So 28 codons will not be affected.

You first use PCR to amplify the fragment so that there is sufficient DNA for sequencing. You carry out dideoxy sequencing and t
dsp73

Answer:

The first attached figure below shows the design of an agarose gel with four sequencing reactions. The second figure presents a photo of an agarose gel, so that you can better understand how the bands are represented in this gel.

Explanation:

To view the bands of four sequencing reactions on an agarose gel, you will need to use a melted agarose gel, plastic combs suitable for that reaction and a container suitable for that type of gel. You will place the plastic combs in the container and pour all the gel into the vat and wait for the melted gel to solidify. The plastic combs will form holes in the hardened gel where the DNA samples will be placed.

Once the gel is hardened, you will remove the plastic combs and begin to apply the sequenced DNA.

The sequenced DNA samples will be mixed with a dye, usually bromophenol blue, which will allow you to visualize the bands formed on the gel. You will also apply the dye to a sample without DNA containing only the dye, which serves as a comparison for the size of the bands.

Each sample of DNA will be plated in the column of holes formed by the plastic combs. Then, this container, with the gel, will be placed in a larger container that contains a loading buffer. The larger container will be closed and an electric field will be applied that will force the DNA samples to be moved from one pole to another inside the container, in this case, the samples leave the negative pole for the positive pole.

After a few minutes, it is possible to visualize the DNA displacement and at the end of the procedure it will be possible to visualize the formation of bands as shown in the drawing and in the figure below. The size of these bands can be compared and analyzed.

What causes agal bloom
Alika [10]

Answer:

Sudden Influx of Nutrients

Explanation:

Algal blooms are caused by a sudden influx of nutrients, coupled with already warm temperatures.  This can happen from fertilizer runoff from farms or chemical industry waste.  They allow algae to quickly grow, but the water reaches carrying capacity.

How do hydrochloric acid and bile salts help digest food?
yan [13]
HCL is guilty for triggering the release of enzymes such as pepsin which are essential for the digestion of protein. Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine.
