Mama L [17]

By predicting how the sodium-potassium pump becomes integrated into outer cell membrane. The prediction that is false is the mRNA coding into sodium pump is translated into the pump on two ribosomes.

<h3>What is sodium-potassium pump?</h3>

The sodium-potassium pump is an enzyme (an electrogenic transmembrane ATPase) present in the membrane of all animal cells. It is also known as sodium-potassium adenosine triphosphatase, Na+/K+-ATPase, or sodium-potassium ATPase. It serves a number of purposes in cell physiology.

The enzyme Na+/K+-ATPase is activated (i.e. it uses energy from ATP). Three sodium ions are exported and two potassium ions are imported for each ATP molecule used by the pump. As a result, each pump cycle results in the net export of one positive charge.

There are four distinct sodium pump isoforms or subtypes in mammals. Each has distinct qualities and patterns of tissue expression. The P-type ATPase family includes this enzyme.

With incomplete dominance a likely ratio of phenotypes in the F2 generation resulting from a monohybrid cross between two true-b
nydimaria [60]

Answer:

A) 1:2:1

Explanation:

Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles.  Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.

In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.

Thus, Option-A is the correct answer
