Mice21 [21]

The product of the lac z gene is an enzyme, this enzyme do in the bacterial cell that enzyme is known as β-galactosidase, that's an important a part of the metabolism of lactose.

<h3>What are lactose restriction enzyme ?</h3>

When a restriction enzyme along with BamHI is used to reduce the plasmid, it might reduce the circle at one place. The reduce could open up the circle withinside the LacZ gene. This is due to the fact gene cloners have located a bit of DNA that has many limit enzyme reducing  in the LacZ gene.

It cleaves (separates) a disaccharide lactose molecule into a ways greater digestible glucose and galactose lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose.

Step 11 of skeletal muscle contraction:__________.
malfutka [58]

Answer:

The suitable option will be - B

B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.

Explanation:

Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.  

Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.  

So, we can say that option B is correct.
