Can someone explain to me in depth the difference between covalence and ionic bonds
Ulleksa [173]
In covalence bonding, the two atoms forming the bond share the electrons between themselves, which is what creates the bond.

In ionic bonding, one atom sees that the other is lacking an electron so, given that it has an electron that it can afford to lose, it gives it to the other atom.

you are a biochemist working for a pharmaceutical company. you have been tasked with identifying a sample of nucleic acid. it is
Lorico [155]

The sample that is being discussed in the problem can be either DNA or RNA.

DNA and RNA are both very important molecules. Both of these hold immense value in biology since they store all the vital information required for living. The basic structures of the two are quite similar; the only difference is that DNA is double-stranded while RNA has a single strand.

DNA and RNA molecules both contain a five-carbon sugar (ribose), a phosphate group, and a nitrogenous base. Except for cytosine, guanine, and adenine, the fourth part is the phosphate group that exists in both. RNA has Uracil while DNA has Thymine.

Since it has not been mentioned here what the fourth part might be, the sample might be a DNA or an RNA molecule.

Describe two factors that are responsible for regulating the cell cycle. What is their role in the regulation process?
finlep [7]

Answer:

The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks, which are positive regulators of the cell cycle, activate cell cycle factors that are essential for the start of the next cell cycle phase.

Explanation:

Listen to pronunciation. (sel-SY-kul REH-gyoo-LAY-shun) Any process that controls the series of events by which a cell goes through the cell cycle. During the cell cycle, a cell makes a copy of its DNA and other contents, and divides in two.
