Why are microdeletions and microinsertions difficult to diagnosis using karyotyping?

Biology

Harman [31]3 years ago

Because only the chromosomes can be seen in a karyotype, and microdeletions or insertions are mutations at the molecular level, it is virtually impossible to detect such mutations at the chromosomal level. 
MrRa [10]3 years ago

Answer & explanation:

Mutations that occur by microinsertions or microdeletions (usually a pair of nitrogenous bases) can result in a change in the reading phase of the gene, completely modifying its translation into a particular protein.

Microinsertions are responsible for inserting a nucleotide into the DNA sequence, while microdeletions remove a nucleotide from the DNA sequence.

Diagnosing microdeletions or microinserts is highly difficult and requires highly skilled professionals, since many of the detected changes represent variations in copy number without clinical significance or of unknown clinical significance.

What are the abiotic and biotic factors of a Beach Coastal?
ololo11 [35]

Answer:

Beaches have specific abiotic factors like sandy, rocky soil, high amounts of sunlight, strong wind, high salinity and changing tides. Despite these challenges many biotic factors survive, such as mangrove trees in tropical areas, and flat, sprawling succulents in sand dunes.

A normal breath takes in about 1.0 L of air. If air has an average molar mass of 28.8 g per 1 mol and has a density of 0.97 g/mL
Ann [662]

Taking into account the definition of density and Avogadro's Number, you take 2.0286×10²⁵ molecules of air.

<h3>What is density</h3>

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

<h3>What is Avogadro's Number</h3>

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

<h3>Amount of molecules of air</h3>

In this case, you know that:

  • Density= 0.97 \frac{g}{mL}
  • Volume= 1 L= 1000 mL

Replacing in the definition of density:

0.97 \frac{g}{mL}=\frac{mass}{1000 mL}

Solving:

mass= 0.97 \frac{g}{mL}  ×1000 mL

<u><em>mass= 970 g</em></u>

Air has an average molar mass of 28.8 g per 1 mol. Then 970 grams are contained in 33.68 moles.

Now, considering the definition of Avogadro's number you can apply the following rule of three: If 1 mole of air contains 6.023×10²³ molecules, 33.68 moles contains how many molecules?

amount of molecules = (33.68 moles× 6.023×10²³ molecules)÷ 1 mole

<u><em>amount of molecules= 2.0286×10²⁵ molecules</em></u>

Finally, you take 2.0286×10²⁵ molecules of air.
