Answer:

Genes that are located on the same chromosome and that tend to be inherited together are called linked genes because the DNA sequence containing the genes is passed along as a unit during meiosis unless they are separated by crossing over.

A spheroidal bacterium with a diameter of 1 mm contains 2 molecules of a particular protein. What is the molar concentration?

creativ13 [48]

Answer : The molar concentration is, $6.35\times 10^{-18}mol/L$

Explanation :

First we have to calculate the moles of protein.

$\text{Moles of protein}=\frac{\text{Number of molecules of protein}}{\text{Avogadro's number}}$

Number of molecules of protein = 2 molecules

Avogadro's number = $6.022\times 10^{23}molecules/mol$

$\text{Moles of protein}=\frac{2\text{ molecules}}{6.022\times 10^{23}molecules/mol}=3.32\times 10^{-24}mol$

Now we have to calculate the radius.

Radius = $\frac{Diameter}{2}=\frac{1mm}{2}=0.5mm=5.0\times 10^{-4}m$

Conversion used : (1 mm = 0.001 m)

Now we have to calculate the volume.

$V=\frac{4}{3}\pi r^3$

$V=\frac{4}{3}\times 3.14\times (5.0\times 10^{-4}m)^3$

$V=5.23\times 10^{-10}m^3=5.23\times 10^{-7}L$

Conversion used : (1 m³ = 1000 L)

Now we have to calculate the molar concentration.

$Concentration=\frac{\text{Moles of protein}}{\text{Volume}}$

$Concentration=\frac{3.32\times 10^{-24}mol}{5.23\times 10^{-7}L}$

$Concentration=6.35\times 10^{-18}mol/L$

Thus, the molar concentration is, $6.35\times 10^{-18}mol/L$
