A plant (1st generation) has a leaf cut off and the leaf is placed in a jar of water by a window. Several weeks later the piece has grown into a new plant (2nd generation). The process is repeated from the second plant for another new plant (3rd generation). Which statement correctly describes the model that shows the genetic relationship between the original plant and the 3rd generation?

Group of answer choices

The two plants have half the same genes.

The two plants have one third the same genes.

The two plants are genetically identical.

There is no way to know the genetic relationship.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.
