Maintenance of normal sinus rhythm
antidysrhytmic drugs are used to treat abnormal rhythm of the heart. Abnormal rhythm is usually due to the irregular electrical stimulation of the electrical activity of the heart. This can work by correcting the cardiac function there are four classes of this drugs such as Class I for sodium channels, Class II which are the beta blocker, Class III which are the drugs that prolong repolarization and Class IV which are the calcium channel blocker.
Answer:
Anaphase
Explanation:
During Anaphase the chromosomes separate and move along the spindie fibers to opposite ends of the cell.
If the lac repressor were altered so it could not release lactose once lactose was bound to it then you would predict that " the repressor could not bind to DNA".
<u>Option:</u> A
<u>Explanation:</u>
A DNA-binding proteins prevent gene expression coding for proteins engaged in bacterial lactose metabolism is understood as the lac repressor.
Such genes are repressed if lactose is not accessible to the cell, meaning that when lactose is available, the bacterium only spends energy in the development of machinery required for the absorption and processing of lactose.
When lactose is accessible, it is transformed into allolactose, which prevents the DNA binding ability of the lac repressor and thus increases the gene expression.
