DNA replication process is the event during which the molecule duplicates. It occurs in the interphase and involved different enzymes, a DNA molecule, and free nucleotides. Image attached.
Whatis DNA replication?DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.
DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.
The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated.
Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.
DNA strands are antiparallel, and replication occurs only in 5'-3' direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.
Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

essay on life of trees
Answer:
hi hope this helps
Explanation:
Trees are our best friends because they clean the air we breathe. Likewise, they also clean the water and soil and ultimately make the earth a better place. It is also a fact that people who live near trees are healthier, fit, and happier than people who do not.it is our responsibility to look after our friends who serve us in many ways. Most importantly by saving plants, we are not doing any favor to plants but to ourselves only. Because trees and plants life does not depend on us but our lives depend on them.Trees are important to us in a lot of ways and we cannot ignore their importance. They are important because they give us fresh air to breathe, food to eat and shelter/shade from sunlight and rainfall. Besides this, there are many medicines in the market that are made up of trees extracts. Apart from this, there are plants and trees that have medicinal value.
They bring peacefulness; create a pleasing and relaxing environment. Also, they help in reflecting the harmful rays of the sun and maintaining a balanced temperature. Besides, they also help in water conservation and preventing soil erosion. They also manage the ecosystem and from ancient times several varieties of plants are worshipped.
Trees provide us many benefits some of which we can’t see but they make a huge difference. They help in fighting back the climate changes by absorbing greenhouse gases which are the main cause of climate change.
Moreover, they replenish groundwater and filter the air from harmful pollutants and odors. Besides, they are a great source of food and the king of fruits ‘Mango’ also grow on trees.When a seed of a plant or tree grow it makes the area around it greener. Also, it supports many life forms. Birds make their nests, many reptiles and animals live on it or near it.
Besides, all these many beautiful flowers, food growing on it. Moreover, many parts of trees such as roots, leaves, stem, flower, seeds, are also edible. Most importantly they never ask anything in return for their services and the gifts they give. Trees also keep the balance in the ecosystem and ecology.
To conclude, we can say that trees are very important and beneficial for every life form on earth. Without them, the survival of life on earth will become difficult and after some time every species starts to die because of lack of oxygen on the planet. So, to save our lives and to survive we have to learn the importance of trees and also have to teach our children the importance of trees.

if you consume one molecule of pyruvate , how many ATP molecules you are going to produce ?
1 NADH -> 3 ATP
1 FADH2 -> 2 ATP
A single molecule of pyruvate will generate 15 ATP molecules.
Pyruvate is an important chemical constituent according to biochemical science. It is the molecule that is produced from glycolysis, a process by which energy is derived from glucose. The carboxylate group of pyruvate is removed as carbon dioxide. The synthesized acetyl group is stimulated through its association with Coenzyme-A, thus, producing Acetyl Coenzyme-A.
The TCA cycle generates 15 ATP molecules through oxidation of Acetyl Co-A. Through oxidative decarboxylation as well as Krebs cycle, a single molecule of pyruvate (containing 3 Carbon atoms) gives rise to 4 molecules of NADH, a single molecule of FADH2 as well as one molecule of ATP.

A virus causes an illness that includes the following symptoms: headaches, fever, and body aches. Symptoms usually occur two to seven days after infection by the virus. What type of reproductive cycle does this virus most likely have?
Answer:
Viruses like Influenza reproduce via the lysogenic cycle.
Explanation:
Viruses are pathogenic, disease-causing microorganisms. They reproduce and spread in a variety of ways, and their life cycle or lytic cycle influences the symptoms of their specific infections.
Influenza viruses, in particular, exploit receptors on the cell surface for entry into the cell. They reproduce by using the host cell's replication mechanism in the nucleus. They and use the host's cellular machinery in order to replicate.
This cycle usually lasts for 2-7 days, after which the virions bus from the host cell, incorporating parts of their lipid bilayers. The viral particles spread via infective particles or droplets from the lung tissue of their host.
Humans are chordates. Which animal group is most closely related to chordates? Question 19 options: annelids arthropods echinoderms cnidarians molluscs
The animal group most closely related to chordates is the echinoderms. This may be surprising at first, as echinoderms, which include starfish, sea urchins, and sea cucumbers, may not seem very similar to chordates, which include humans, fish, and birds.
However, both echinoderms and chordates belong to a larger group of animals called deuterostomes, which are characterized by several key embryonic developmental features, including the formation of the mouth secondarily, the presence of a coelom, and radial cleavage during embryonic development.
In contrast, the other animal groups listed as options are all protostomes, which means that they undergo different embryonic developmental processes, including the formation of the mouth first during development, spiral cleavage, and the presence of a blastopore that eventually develops into either the mouth or the anus.
Therefore, although echinoderms and chordates may look very different as adults, their shared developmental features suggest a closer evolutionary relationship than either group has with protostomes such as annelids, arthropods, cnidarians, or mollusks.
Overall, understanding the relationships between different animal groups helps us to better understand the diversity of life on Earth and the evolutionary history of different organisms.
