Why did Hershey and Chase radioactively label viral DNA with 32P and viral protein with 35S? (Figure 13.5)
MArishka [77]
Basically you can answer the question if you know the meaning of 32P and of 35S.

32P means Phosporus-32 (32 is the mass) and 35S means the Sulfur isotope with mass of 35 (it's the most radioactive of all the sulfur isotopes btw).

So we can see that the names have to do with Sulfur and Phosphorus - therefore, the best answer is the following one:

<span>C. Because DNA contains phosphorus and proteins contain sulfur</span>

What is the function of the following organelles?
MrRa [10]

Answer:

Explanation:

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.

The plasma membrane is the same as a cell membrane

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

​Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.

The lac operon in E. coli controls the gene expression of the enzymes that digest lactose in the cell. In the absence of lactose
erma4kov [3.2K]

Answer:

b, a, d, c, e

Explanation:

The lac operon is called lactose operon is a cluster of genes with a promoter. The bacteria uses lactose as the source of energy by the proteins coded by genes. This is present in prokaryotes.

The regulatory gene codes for repressor protein. The repressor binds to lactose and prevent its binding to operator. In the absence of lactose repressor gets activated and binds with operator. Thus, RNA polymerase is prevented from binding the promotor. The transcription of genes inhibited. Thus correct order is b, a, d, c, e.
