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.
Anatomy of the Bladder ï¨ On the posterior wall of the bladder; lying immediately above the bladder neck, is a small triangular area called trigone ï¨ The trigone can be identified by the fact that its mucosa is smooth, in contrast to the remaining bladder mucosa, which is folded to form rugae.
