Which statement about Sanger sequencing is false?

Biology
1 answer:
Likurg_2 [28]3 years ago
8 0

Answer:

D) To read the DNA sequence of the synthesized strand in the 5'-to-3' direction, the gel is read from top to bottom.

Explanation:

The DNA sequence of the synthesized strand in the 5'-to-3' direction is read from the bottom to the top. On the electrophoresis gel, bands corresponding to the smallest DNA fragment migrate to the bottom of the gel.  Meaning, the DNA primer fragment would be at the bottom and immediately above it would be the fragment that had fewer dNTPs (deoxynucleotidetriphosphates) incorporated prior elongation termination by an incorporated ddNTP.

romanna [79]

The conclusion that coral does not grow well in conditions with high salt is invalid because (B)  The experiment changes more than one variable at once.

In order to correctly study the effect of three variables on there needs to be, 3 x 3 x 3 = 27 different aquariums (every variable takes 3 different values and there are 3 different variables).

In these aquariums, only one condition needs to be varied at a time to study its effect. To study the condition with high salt, the temperature and pH needs needs to be kept fixed at a particular value whilst varying the salinity from normal to low to high.

What advantages are provided to developing reural areas by using an anaerobic digester?
erastovalidia [21]

The advantages that are provided to developing rural areas by building and using an anaerobic digester is that anaerobic digesters offer both a source of energy and a sanitary method of waste disposal which can help control disease.

<h3>What is an anaerobic digester? </h3><h3> </h3>

An anaerobic digester is a tank. It's a tank in which the size and appearance change considerably depending on what use is the digester being applied for.

  • A variety of anaerobic digesters is the household digester which is used for a single family. It has a volume of less than one cubic metre.
  • In an industrial-scale anaerobic digester. The size can easily surpass 5,000 cubic meters.
  • A digester used on a farm or a ranch has a typical capacity of a few dozen cubic meters.

Therefore, the advantage is that anaerobic digesters offer both a source of energy and a sanitary method of waste disposal which can help control disease.
