What would be the effect of a mutation in the coding region of the lactase gene?

Biology

Fynjy0 [20]3 years ago
5 0

Lactase refers to an enzyme that can dissociate lactose sugar into glucose and galactose. This enzyme plays an important role in the digestion of milk that comprises high lactose sugar. In case, if a mutation occurs in the gene codon of lactase, then two possibilities can take place. These are as follows:  

1. Loss of mutation: In this case, the person becomes lactose intolerant because of mutation in lactase gene codon. Due to this, there is low mRNA expression and thus low production of the enzyme lactase. This is also known as lactase non-persistent phenotype.  

2. Gain in mutation: In this case, the person gain an increase in mRNA expression of the lactase gene, thus more production of lactase takes place than usual. This kind of individual exhibits lactase persistent phenotype.

In the formula, E K = 1/2 • m • v 2 if mass (m) was doubled, how much would kinetic energy
Viktor [21]

Answer:

mass doubled makes KE twice as large

velocity doubled makes KE 4 times as large

Explanation:

Try it with an example

m = 4

v = 8

KE = 1/2 m * v^2

KE = 1/2*4 * 8^2

KE = 1/2 * 4 * 64

KE = 128

Now double the mass

m  = 8

v = 8

KE = 1/2 8 * 8^2

KE = 1/2 8 * 64

KE = 4 * 64

KE = 256 double what it started out as.

Now do it again.

m = 4     That was the original mass

v = 16

KE = 1/2 4 * 16^2

KE = 2 * 256

KE = 512

When the velocity is doubled the KE becomes 4 times as big.

4*128 = 512

Why does cellular respiration need energy
Kryger [21]

Answer:

The cells of living things also get energy by "burning." They "burn" glucose in the process called cellular respiration. Inside every cell of all living things, energy is needed to carry out life processes. Energy is required to break down and build up molecules and to transport many molecules across plasma membranes.

What are two main processes must carbon go through?
mestny [16]
There are 3 main processes that carbon dioxide (co2) must go through :

Respiration -  All plants and animals are able to release energy from their food using respiration. This can also include any other living organism out there.

Combustion - This is the process of burning fuel. This releases carbon dioxide into the open space.

Photosynthesis- Any sort of g<span>reen plant, such as flowers, can remove carbon dioxide from the atmosphere by using photosynthesis. </span>
