In an experimental situation, a student researcher inserts an mrna molecule into a eukaryotic cell after he has removed its 5' cap and poly-a tail. which of the following would you expect him to find?

(a)the mrna could not exit the nucleus to be translated.
(b)the cell recognizes the absence of the tail and polyadenylates the mrna.
(c)the molecule is digested by restriction enzymes in the nucleus.
(d)the molecule is digested by exonucleases since it is no longer protected at the 5' end.
(e)the molecule attaches to a ribosome and is translated, but more slowly.

its the cell wall and the they are unique to plant

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
