Answer:
The transitional epithelial tissue is perfect for bladder function because it has the ability to stretch.
When the bladder is empty, the cells have a cuboidal shape. When the bladder is full, the cells have a flat shape.
Explanation:
Transitional epithelial tissue is the tissue that makes up the entire bladder and some organs of the urinary system. This tissue has the ability to allow the organs covered by it to have the ability to change shape and size, because this tissue allows these organs to stretch, so it is the perfect tissue to cover the bladder.
As we know, the bladder is the organ responsible for storing urine. When it is filled with urine, the bladder stretches, at that moment, the bladder cells are compressed and assume a flat, stretched shape. When it is empty, the bladder shrinks in size, becoming "wilted", at that moment, its cells assume a cuboidal shape.
Answer:
Use a step wise process
Explanation:
In order to find the presence of the recombinant protein:
- Culture the cells that you believe harbors the plasmid for the recombination protein (+) and also cells that do not (-). This is your control.
- Extract the plasmid from both strains.
- Observe the plasmid map and the area of your insert. Use this to select the restriction enzymes at the beginning and the end of the YFG gene. You can also use a restriction site inside the gene but not in the plasmid for better control.
- Perform the restriction enzyme digest on both (+) and (-) according to your protocol and separate using gel electrophoresis.
- Observe the separate bands that you see. In the (+) there should be a band that is the size of your insert and a larger band that is the size of your plasmid control band and in the (-) there should be a single band that is the size of the plasmid but non the size of the insert.
