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.
Wikipedia notes that rugae are located in other parts of the body. They are found in the wrinkles of the scrotum in males and in the vagina in females. They are also found in the hard palate, which is located directly behind the upper anterior teeth. The gall bladder and the inside of the urinary bladder also contain rugae.
