Therefore, whenever a ddNTP is added to a growing DNA strand, it is unable to chemically bind with the next nucleotide in the chain, and the DNA strand stops growing. Figure 3: By adding together information about all of the truncated strands, researchers can determine the nucleotide sequence of the DNA target.
Functions of the Bladder. Temporary store of urine â The bladder is a hollow organ. The walls are very distensible, with a folded internal lining (known as rugae), this allows it to hold up to 600ml. Assists in the expulsion of urine â During voiding, the musculature of the bladder contracts, and the sphincters relax.
Answers. Best Answer: rugae or folds give the stomach its well-known ability to enlarge when engorged with food. the outermost layer of these folds is mucus which helps protect the tissues below from the harsh environment of the stomach. The innermost layer is a lining of simple columnar epithelium.This type of epithelium provides the greatest surface area for absorption or secretion. In the stomach the epithelial cells exposed to the lumen are primarily constructed to resist digestion by the lumen contents.nswers.
