Scientists take the advantage of plasmids having antibiotic resistance gene by using them as a vectors to clone, transfer and manipulate genes and also detecting the growth of such plasmids in selective media.

Plasmids are the extrachromosomal DNA present in bacterial cells. These are circular double stranded DNA molecules that can replicate on their own. Plasmids are known to exist in some archaea and eukaryotes as well. Usually consisting of DNA, some species are known to contain RNA as genetic material as well.

Vectors in laboratories are the agents that are used to transfer the gene of interest into the desired host cell. Vectors can be of two types: cloning vectors and expression vectors.

In the particular case given in the question, the compound is a competitive inhibitor.

Enzymes are biocatalysts. Like other catalysts, it can lower the activation energy and drive the reaction in the desired direction. Because their activity depends on protein folding, they are usually sensitive to the temperature, pH, and salt concentration of the environment in which they work. The substrate enters the active site of the enzyme to form the enzyme-substrate complex. A reaction then takes place, converting the substrate to a product and forming an enzyme-product complex. Now the product is  released from the active site of the enzyme.

First, an increase in substrate concentration leads to an increase in the rate of enzyme-catalyzed reactions. This rate increase plateaus when the enzyme molecules become saturated with substrate. The rate of enzyme-catalyzed reactions increases with increasing concentrations of the enzyme.

The blank AT/GC rule states that blank complementarity between DNA strands is necessary for DNA replication.

Chargaff's Rule states that during the replication process, all replication must match complementary purines, pyrimidines, or nitrogenous bases. DNA always couples adenine and thymine together, but cytosine always couples with guanine.

According to the base pairing rule, guanine always joins with cytosine, whereas adenine always unites with thymine. They keep the two strands of DNA connected, but they are too weak to undergo replication.

Medication is to be taken as soon as possible for fevers.

The right response is B.

What advantages does having a fever have? No sickness causes a fever. It is an indication that your body is struggling to fight off a disease or infection. Fever activates the body's defenses, causing white blood cells and other "fighter" cells to be sent to battle and eradicate the infection's root cause.

Your immune system can fight infections in two ways with the aid of a fever. The body's internal temperature affects how quickly cells function, particularly those that fight disease. They can react to encroaching pathogens more quickly. Additionally, bacterial and viral growth is hampered by greater body temperatures.

When a boom thing binds to the extracellular area of a RTK, its dimerization is brought on with different adjoining RTKs. Dimerization results in a fast activation of the protein's cytoplasmic kinase domain.

Dimerization of the EGF receptor has been described as a mechanism for activation of the kinase activity and signal transduction through the EGF receptor.

Dimerization stimulates receptor PTK activity. Monomeric receptor PTKs exhibit weak basal activity (Inactive). Ligand-induced receptor dimerization increases the local concentration of the kinase domain leading to more efficient transphosphorylation of tyrosine residues in the mobile activation loop.

According to the pressure-flow hypothesis, sucrose and water flow up the stem in the phloem when roots are sources and leaves are sinks.

According to the Pressure-Flow Hypothesis, water containing food molecules passes through the phloem under pressure. The differential in water concentration between the solution in the phloem and the comparatively pure water in the neighboring xylem ducts causes the pressure.

the contents of the phloem experience a drop in osmotic pressure.

The comparatively clean water that is still in the phloem eventually escapes through osmosis or is drawn back into the neighboring xylem vessels by transpiration-pull. Thus, the phloem contents are forced up and down through the sieve elements by the pressure gradient between "source" (leaves) and "sink" (shoots and roots).

During the cell cycle's M stage (mitosis), a divides into two identical new cells.

When aberrant cells congregate, a solid material of tissue called a tumor is created. Tumors can affect the bone, epidermis, tissue, organs, and glands. Whenever cells in the organ divide and enlarge excessively, tumors frequently form. The body typically controls how quickly cells grow and divide. New cells either take the place of older ones or perform new roles. To make way for healthy cells, damaged or extra cells die. New cells replace those that are lost as a result of aging or damage. This methodical procedure occasionally goes wrong, allowing damaged or abnormal cells to proliferate while they shouldn't. These cells have the ability to develop into tumours, which are tissue lumps. Malignant tumors could or might not exist (benign).

The two resulting daughter cells would not be completely identical if divide first and then duplicate chromosomes.

The replication that occurs after division would generate mutations, which couldn't be repaired according to the parent cell. In this case, the genetic information would be inherited less accurately. This way of cell division would be disadvantageous for organisms and would likely be eliminated.

Normally before the cell divides completely, the chromosomes are duplicated identically and this division has several checkpoints to ensure that the process is going well. It is regulated by cyclin proteins. if it doesn't clear the checkpoint, it will not be allowed. So chromosome division is very well organized by the cell.
