Answers

Answer 1

DNA fragments may be resolved using migration through a gel matrix called agarose. The largest linear fragments will travel the slowest while the smallest ones will travel the fastest.

A technique to separate DNA fragments (including other macromolecules like proteins and RNA) based on their charge and size is called gel electrophoresis. The molecules, based on their size and charge, will travel through the gel in different directions or at different speeds, which allows them to be separated from one another. Larger/longer pieces of DNA will travel through the pores of the gel matrix slower than the shortest/smallest ones.

Gel electrophoresis involves a gel, as the name suggests. For DNA separation, the gel is made out of a polysaccharide called agarose.

Even though plant cells photosynthesize, they still use their mitochondria for oxidation of pyruvate and cellular respiration this will occur in all cells all the time .

What is cellular respiration in plants?The process by which sugar is broken down in the presence of oxygen in the mitochondria of organisms (animals and plants) to release energy in the form of ATP is known as cellular respiration. Water and carbon dioxide are waste products of this process.  Plants can carry out cellular respiration because they have mitochondria.Oxidation of pyruvate in plants:Eukaryotic cells' mitochondrial matrix is the site of pyruvate oxidation.Pyruvate becomes an acetyl group connected to a carrier molecule of coenzyme A when oxygen is present. The resultant acetyl CoA can enter a number of pathways, although the citric acid cycle is usually where the acetyl group is given for further catabolism.

Answers

Reverse transcriptase, integrase, protease. Reverse transcriptase (RT), integrase (IN), and protease (PR), the three viral enzymes, are all promising therapeutic targets during an HIV infection.

White blood cells called CD4 cells, which help the body fight disease and infection, are destroyed by HIV. A CD4 cell that has been infected by the virus is reprogrammed to produce new HIV copies. HIV requires the assistance of the enzymes reverse transcriptase, protease, and integrase to accomplish this. The main HIV medicine classes function by inhibiting these enzymes and preventing CD4 cells from becoming HIV replicators.

Inhibitors of nucleoside reverse transcriptase (NRT) have defective forms of the genetic components that HIV employs to infect CD4 cells. The HIV gene cannot be inserted into the healthy cell when the reverse transcriptase HIV enzyme uses these flawed building pieces.

By interfering with this procedure, the virus cannot replicate in CD4 cells.

Anti-Protease Agents

The generation of protease, a protein required for HIV to replicate itself in a CD4 cell, is inhibited by protease inhibitors.

Meiosis is the process that germline cells use to divide and produce four gametes, each with half the number of chromosomes as the parent cell. During meiosis, the DNA of the parent cell is randomly divided between the four gametes. This random division of DNA can lead to mutations.

When part of the input to a neuron is lost, the nerve fibers of the undamaged neuron form new connections to replace the lost ones this is called axonal sprouting.

What is meant by axonal sprouting?

Inside a nerve cell, there is a cell body, dendrites, and an axon that has a specific function. The nervous system consists of many neurons. Neurons function as senders of messages (impulses) in the form of stimuli or responses.

The axon is a long extension that extends from the cell body. Its function is to transmit impulses from the cell body to other neurons. The axon has a sheath for wrapping. The axon sheath is composed of Schwann cells. The inner sheath of Schwann cells that directly covers the axon is called the myelin sheath. This sheath is a layer of fat. Meanwhile, the outer axon sheath of Schwann cells is called neurolemma. Myelin sheath functions as a protector and also provides nutrition to the axon. Schwann cells help regenerate damaged axons. Axonal sprouting is the process by which fine nerve processes (budding) grow from intact axons to re-innervate denervated muscle fibers. The buds thus sustain the nerve supply to the muscles and, in turn, the ability to move. The myelin sheath does not completely cover the axon. The part or point on the axon that does not completely wrap around the axon. The part or point on the axon that is not covered by the myelin sheath is called the node of Ranvier. This node serves to accelerate the delivery of nerve stimulation.
