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.
The Detrosor Muscle of the Urinary Bladder. The Detrusor Muscle is a layer of the Urinary Bladder wall which is itself made up by three layers. The Detrusor Muscle is smooth muscle fibers arranged in spiral and circuar bundles.When the urinary bladder is stretched the parasympathetic nervous system is signaled to contract the detrusor muscle and the urine is squeezed out through the urethra canal.For this to work both the autonomically controlled sphincter muscle and the voluntarily controlled sphincter muscle must be relaxed.hen the urinary bladder is stretched the parasympathetic nervous system is signaled to contract the detrusor muscle and the urine is squeezed out through the urethra canal.
