“DNA” stands for: Deoxyribonucleic Acid
The researchers used different radioactive elements to label the DNA and proteins in viruses. This allowed them to identify which molecule the viruses inserted into bacteria. DNA was the molecule they identified. This confirmed that DNA is the genetic material.
Answer:
A) An early step in the path to thromboxanes is blocked by ibuprofen.
Explanation:
Eicosanoids are signaling molecules that are produced by oxidation of arachidonic acid or other twenty-carbon essential fatty acid. Eicosanoids are involved in immune responses: they inhibit inflammation, allergy, fever, they also regulate pregnancy, childbirth, control cell growth..
Synthesis of prostaglandins, prostacyclin and thromboxane (subfamilies of eicosanoids) is inhibited by aspirin and some anti-Inflammatory drugs such as ibuprofen and naproxen.
Answer: DNA growth does not occur
Explanation:
Here, the cell has grown, the DNA has been replicated (this takes place in the S phase of interphase) and its almost time for the cell to divide. Basically, what occurs during the G2 phase (Gap 2 phase of interphase) includes duplication of all proteins and organelles needed later during the process of cell division. Some of these includes assembly of microtubles will later for the spindle structure that that helps in the separation of chromosomes during the M phase but these are produced during the G2 phase.
The cells also continue to increase/grow in size and the volume of the cytoplasm also increase in this phase. There is also a checking where the cell needs to check for the structures and components and to also ensure that they are all present
<span> Some of the important features of a prokaryotic cell is that it contains a plasma membrane, ribosomes, and genetic material (DNA) that is not bound by a membrane. Therefore, prokaryotic cells lack a nuclear membrane. </span>
