) You treat some cells with a proteolytic enzyme that is too large to penetrate the cell membrane (Set 1). Another group of cell
Advocard [28]

Answer:

Proten W

Explanation:

SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).

When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).

Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.

kifflom [539]

The answer is there (3). This is because a mitochondrion has it own DNA called mitochondrial DNA.

Somatic nucleus transfer is the medical procedure used when the biological mother has mitochondria disorder which she would not wish to pass to her offsprings (which are inherited maternally).

Which of the following statements about adaptive radiation is correct? View Available Hint(s) Which of the following statements
Amanda [17]

Answer:

Adaptive radiation occurs within a single lineage

Explanation:

Adaptive radiation generally occurs when an organism enters a new area and different traits affect its survival. An adaptive radiation is a burst of evolution, creating several new species out of a single parent species, which simply means that adaptive radiation occurs when a single lineage produces many descendant species. Adaptive radiation is considered to be a rapid process, where adaptation from a recent common ancestor takes place in a short period of time (with respect to geological time, of course).

_____ is an explanation for Alzheimer's disease that suggests that changes in aging brain cells may trigger an autoimmune respon
LekaFEV [45]

Answer:

Autoimmune theory

Explanation:

Alzheimer's disease  is the most common type of neurocognitive disorder, which usually occurs after the age of sixty-five and is characterized mainly by memory impairment.

The autoimmune theory suggests that <u>the immune system is prearranged so that it becomes unable to identify the body's proteins from foreign ones</u>. As a result, the immune system attacks its own cells.
