Leeks are root vegetables that look quite similar to onions, to which they are related. Their flavor is onion-like but much milder. People who avoid this vegetable because they don't like onions should try them â their flavor is mellow and not overpowering, and many onion-haters enjoy them. Unlike onions, leeks don't form much of a bulb on the end of the root. Instead, they remain cylindrical, with perhaps a slight bulge at the end. The part of that is under ground remains tender and white, while the part exposed to the sunlight becomes tough and fibrous and not very good for eating.
The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells.In prokaryotes which lack a cell nucleus, the cell cycle occurs via a process termed binary fission.n cells with a nucleus, as in eukaryotes, the cell cycle can be divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for cell division and duplicating its DNA.
DNA replication is the action of DNA polymerases synthesizing a DNA strand complementary to the original template strand. To synthesize DNA, the double-stranded DNA is unwound by DNA helicases ahead of polymerases, forming a replication fork containing two single-stranded templates.Replication processes permit the copying of a single DNA double helix into two DNA helices, which are divided into the daughter cells at mitosis.nitiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase Î± occurs on the leading strand. The priming event on the lagging strand establishes a replication fork.
