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.
Answer:
A trust me.
Explanation:
are you functional adaption is an adaption that helps an organism survive in a certain environment, typically altered by a physical stimuli, dietary changes, or injury.
I believe the correct answer from the choices listed above is option 4. This type of research is often successful in advancing knowledge regarding the functioning of human cells because <span>cellular research using mice can always be applied to human cells since all complex organisms produce the same proteins.</span>
