In an experiment, a scientist makes a radioactively labeled probe using human DNA. She then discovers that the probe hybridizes to a small segment
of DNA isolated from a plant. What can she conclude from her results?
O A. The plant might have a gene that is similar to a human gene.
B. A plant cell has a cell wall, whereas a human cell does not
C. The wrong method was used to detect radioactively labeled DNA.
D. Plant DNA was accidentally used as a template to make the probe.

a. g2. b. g1. c. m

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
