DNA, which is contained in the nuclei of cells, is the genetic information that carries the instructions for making proteins. Protein synthesis is divided into two phases - transcription and translation. During transcription, the information encoded in the DNA is transferred to a messenger molecule, mRNA, while in the nucleus. Then, the mRNA travels into the cell's cytoplasm where it is translated into a protein molecule.

Some types of cells require synthesis of large quantities of protein. These cells contain multiple nuclei to speed the synthesis process. Which of the following would most benefit from having multiple nuclei?
A.
red blood cells
B.
kidney cells
C.
skeletal muscle cells
D.
lung cells

Red flowered snapdragons are crossed with white flowered snapdragons, producing all pink snapdragons in the f1 generation. what would you expect if you crossed pink with pink? 3/4, 1/4, 1/2 red, 3/4,/1/2,/1/4 pink,1/2, 3/4, 1/4 white

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
