Answer:
The monomers of DNA are individual nucleotides: cytosine, guanine, adenine, and thiamine, (A, T, C, G, respectively). Since DNA is a double-stranded molecule, each nucleotide has a match that chemically interacts with it to form nucleotide pairs
Explanation:
Answer:
prophase
Explanation:
Prophase is when the nuclear membrane degrades. Metaphase is when the chromosomes align in the middle of the cell. Anaphase is when the chromosomes are pulled apart. Lastly, telophase is when one cell splits into two separate cells.
The three phases of signal transduction is (1) reception, (2) transduction, and (3) response. Reception involves the binding of a ligand, may it be a hormone or a neurotransmitter; to a receptor, may it be a membrane receptor, cytosolic receptor, or a nuclear receptor. After binding of the ligand to the receptor, there will be signal transduction of events that will ultimately form a response. For instance, insulin actin on the insulin receptor will trigger a series of events that will increase the transcription of the gene translating for glucose transporters and ultimately, increase the number of glucose transporters embedded in the cell membrane leading to increased glucose uptake in tissues.
<span>The correct answer is 'metastasis'. This is the migration of cancer cells from one place to another in the body. They do this by travelling through the blood stream or the lymphatic system.
Mitosis is the process of asexual cell division. It produces cells that are identical to the original cell as one cell divides into two after replicating its organelles and genetic information. (Mitosis makes my toes.)
Apoptosis is controlled cell death. When cells are getting old then they need to be replaced. Old cells are programmed to 'die' at the correct time. The cell contents are recycled to make new cells.</span>
