A cytologist is examining a tissue under an electron microscope. He notices that the endoplasmic reticulum of each cell is extre

mely rough in appearance and he knows that the rough appearance is because of the ribosomes embedded there. He asks why there are so many ribosomes. You respond, _________.A. This tissue exports lipids and is very involved with mRNA which of course is used in protein synthesis.B. This tissue exports proteins to other areas of the body. C. This tissue exports lipids to other areas of the body.D. This tissue exports various nucleic acids, hence the large number of ribosomes present on the endoplasmic reticulum in each of those cells.

Answer:

B. This tissue exports proteins to other areas of the body.

Explanation:

The endoplasmic reticulum is a tubular, flattened sac-like structure that forms a continuous structure with the nucleus.

The endoplasmic reticulum may or may not be attached to another organelle called the ribosomes. The ribosome is associated with the translation of mRNA molecules to protein synthesis.

As the protein is synthesized, the proteins enter the endoplasmic reticulum which modifies the proteins and then package them for the transport to their destined site.

Since the endoplasmic reticulum is involved in the process of transport as it modifies the protein molecule therefore is most appropriate option.

Thus, Option-B is correct.

An organism's genomic dna is analyzed and found to contain 22% thymine. what percentage of that organism's dna is guanine?
abruzzese [7]
In an organism's genomic data, 100 percent is made up of adenine, cytosine, guanine and thymine. Adenine and thymine are complementary pairs in a DNA so they should have the same concentration in the DNA. This would also be the case for Cytosine and Guanine. We are given 22 percent of thymine so we also have 22% of adenine. This would leave us with only 100-22 = 78 percent for both guanine and cytosine. And since they are present in equal amounts, we simply divide the remaining percentage by two to determine the amount of each. Therefore, there would be 78 / 2 = 39 percent of guanine present in that certain DNA.
