Free_Kalibri [48]3 years ago
5 0

The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.

The quantity and quality of DNA can be greatly improved by performing PCR.

* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.

The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.

if a mutation appears in one individual that changes one base in a dna sequence to another base in a DNA sequence ot another bas
irakobra [83]

Answer:

The mutation will be fixed by genetic drift.

Explanation:

Genetic drift is the change in the allele frequencies in a population that occur randomly. It is an evolutionary process (like natural selection), that is associated with the reduction in genetic diversity by the fixation of rare allelic variants and neutral mutations. In this example, this point mutation is neutral since, according to data, the population is evolving by genetic drift. Moreover, it is also important to note that a mutation that involves one nucleotide is also called Single Nucleotide Polymorphism (SNP).

If a woman with vaginal bleeding reports syncope, the EMT should assume that she: Select one: a. has an ectopic pregnancy. b. is
sergiy2304 [10]

If a woman with vaginal bleeding reports syncope, the EMT should assume that she "is in shock".

<u>Option: B</u>

<u>Explanation:</u>

The most common form of syncope is the Vasovagal syncope. It is triggered by a dramatic drop in blood pressure, resulting in a decline in blood flow to the brain. When one stand up, gravity causes blood to settle down below one's diaphragm, in the bottom part of their body.

It is a component of a wider class of medical conditions which may lead in TLOC involving postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension and neurologically mediated syncope (NMS). The overlapping of such clinical symptoms causes confusion about the category of syncopes which may complicate assessment approaches and present difficulties for diagnosis and treatment, especially in young women.

Bacteria can be altered to produce a specific protein by introducing a sequence of DNA into their genes. This bacteria is called genetically modified bacteria. Bacteria that producing insulin called transgenic because they have genes of other species transplanted on them.
