Answer:

Eukaryotic cells evolved from prokaryotic cells.

In a given population of Drosophila, curly wings (c) is recessive to the wild-type condition of straight wings (c+). You isolate
bixtya [17]

Answer:

B) 300

Explanation:

There are two types of alleles present for wing type in this population of Drosophila, c and c+. Various combinations of these two alleles will produce different phenotypes.

c+c+ : straight wings = 45

c+c: straight wings = 70

cc: curly wings = 35

Total flies = 150

Each fly has one gene with two alleles for wing type. Hence 150 flies will have 300 alleles in the gene pool.

How is a cesium gradient used to separate dna with different densities?
Romashka [77]

Cesium is used in the separation of DNA with different densities. Cesium chloride (CsCl) acts as a density gradient for the separation of the DNA (Deoxy ribonucleic acid), and is used in gradient centrifugation.

CsCl density centrifugation:

  • CaCl solution is kept in the centrifuge tube along with the DNA sample to be separated.
  • The centrifugation causes the solutions to form bands with the denser part at the bottom and the least denser part at the top.
  • The DNA with its density similar to a particular layer of CsCl solution density forms a band in that layer.
