RNAi-based modification of amylopectin content in wheat occurs through decreased expression of starch-branching enzymes. If the

siRNA used to knock down plant starch-branching enzymes was transmitted to humans, what enzyme might it affect, and why would this be harmful

If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.

Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.

The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.

In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).

The difference in lipid and protein composition between the membranes of the endomembrane system is largely determined by the __
Maksim231197 [3]

The options to the given are:

A) The physical separation of most membranes from each other.

B) the transportation of membrane lipids among the endomembrane system by small  membrane vesicles.

C) The function of the Golgi apparatus in sorting and directing membrane components.

D) The modification of the membrane components once they reach their final  destination.

E) the synthesis of different lipids and proteins in each of the organelles of the  endomembrane system.

Answer: Option C

Explanation:

The difference in the lipids and proteins composition of the different membrane is different.

Different endomembrane system have different composition of the lipids and proteins in its membrane according to the function of he membrane.

The sorting and direction of the proteins is the function of golgi body. So, it is by the action of the golgi body that the distribution and the sorting of the protein molecules are done.

The protein once formed need to be modified and sorted before being functional into the organelles.

Which of the following statements about natural selection is TRUE?
diamong [38]

Answer:

A. Natural selection results in those individuals within a population who are best-adapted surviving and producing more offspring. The traits that promote survival are heritable.

Explanation:

Natural selection works on the genetic variations that are already present in the natural populations. Some organisms of a population are more likely to produce more offspring than the others. This is due to the presence of beneficial genetic traits in these individuals that impart survival and reproductive fitness to them. Natural selection favors those individuals. Over the generations, the frequency of the beneficial genetic trait in the population increases.

Based on the diagram below, which part of an atom has the greatest mass?
Juli2301 [7.4K]
The nucleus will have the greatest mass. Among the 3 kinds of subatomic particles, electrons are the lightest (by several orders of magnitude), protons and neutrons are much closer is magnitude, though neutrons are slightly heavier. However, in the diagram, the nucleus contains both the neutrons and the protons, so its combined mass would be heavier than either the neutrons alone or the protons alone.
