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.
Most commonly the term is applied to the internal surface of the stomach (gastric rugae). The function of the rugae is to allow the stomach, or other tissue, to expand when needed. When the stomach is not full, the rugae are folds in the tissue. However, as the stomach fills it expands by unfolding the rugae.
