The lac repressor prevents the lac genes in the DNA of E. coli from being expressed most of the time. The answer to your question is A. I hope this is the answer that you are looking for and it comes to your help.
Compounds are made up of elements.
Elements are the ones we pull straight out from the periodic table.
For example:
H2O, HCl, NaCl, NaOH --> these are all compounds
H, N, B, Ne, Na, Cl, O, K --> these are all elements.
They can be described through GENOTYPE because dominant always shows through phenotype.
According to a source, the answer is <u>A. M phase–Cell growth before DNA replication.</u><span>
Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer). </span>
