QUESTION 31 Chipmunk mitochondrial DNA was fingerprinted using the single primer amplified region technique (SPAR) and the PCR r

eaction. One four base primer was used. If the DNA from chipmunk mitochondria is a circlular piece of DNA about 16000 base pairs long, how many fragments should be produced by this technique

Answer:

It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)

Explanation:

The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.

At the equator, there are no
NISA [10]

The reason why at the equator, there are no summers or winters, only wet and dry seasons is : Because at the equator the daytime, night time, temperature and sunlight are moderate.

<h3>Meaning of equator</h3>

An equator can be defined as an imaginary line that runs from west to east thereby dividing the earth into two equal part.

The equator divides the earth into the northern and southern hemispheres. because the equator is at the middle every thing that is experienced there is moderate, unlike the those at the polar region.

In conclusion, The reason why at the equator, there are no summers or winters, only wet and dry seasons is Because at the equator is at the middle and therefore the daytime, night time, temperature and sunlight are moderate.

In a nucleotide, which would change based on the genetic code of the organism?
Setler79 [48]

Answer:

The correct answer is nitrogen base

Explanation:

The nucleotide sequence of one codon differ from that of another codon by the presence or absence of specific nitrogen base.The nucleotide sequence of different codons contain different nitrogen bases.

       As a result change in genetic code result from the change in the nitrogen bases of the codons present in the genetic code.

  In simple words change in single nitrogen base of a codon will change the entire codon.

siniylev [52]

Answer;

-Sympathetic nervous system

After cheering wildly at an exciting football game your body may begin to relax on the way home. This relaxation reflects activity of the sympathetic nervous system.

Explanation;

The sympathetic nervous system is part of the autonomic nervous system, which also includes the parasympathetic nervous system.

The sympathetic nervous system activates what is often termed the fight or flight response. Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons. Sympathetic neurons are frequently considered part of the peripheral nervous system (PNS), although there are many that lie within the central nervous system
