Is it possible to genetically engineer bacteriophages into viriophages ?

OK. Theoretically, phages can be modified into "virions" by recombining genes.

Scientists have found that it is not possible to change phages to phages by genetic means, because it is difficult for humans to modify the structure of the virus itself.

It is not possible to genetically transform a bacteriophage into a phage poison. Bacteriophages and bacteriophage poisons are two types of microorganisms, the former is not harmful to humans but is beneficial, and the latter is very harmful to humans.

When a bacteriophage infects a bacterium, only the DNA of the phage is injected into the bacterium, and the phage can replicate and synthesize a protein, indicating that it can control the synthesis of protein.

There are no variations here, and there are three main types of heritable variations: genetic recombination, genetic mutation, and chromosomal variation. When the phage invades the bacteria, only the DNA of the phage is injected into the bacteria, and the phage can replicate and synthesize the protein, indicating that the branch fighting can control the synthesis of the protein.

Didn't the genetic recombination occur?

No. Here's how he works.

Principle: Isotope 35S will only label proteins, and Isotope 32P will only label DNA. Tracking 35S and 32P can tell where the tagged proteins and DNA are going.

Infect label-free bacteria with bacteriophages containing labeled eggs, acrylics, and DNA. After a short period of time, the bacteria are centrifuged to observe the radioactive properties contained in the bacteria. 1. If it contains 35S and 32P at the same time, it means that both protein and DNA have entered the bacterium, and there may be two kinds of substances that are indispensable for heredity 2. If it contains 35S at the same time, it means that the protein has entered the bacterium, indicating that the protein is the genetic material 3.

DNA or RNA, both. The phage is small in size, and its morphology is tadpole-shaped, microspherical and slender-shaped, and tadpole-shaped is more common. Bacteriophages are made up of nucleic acids and proteins.

Proteins play a role in protecting nucleic acids and determining the shape and surface characteristics of bacteriophages. There is only one type of nucleic acid, which is DNA or RNA, double-stranded or single-stranded, circular or threaded.

Bacteriophages are viruses that invade bacteria and are also the genetic material that gives biological traits to the host bacteria. Bacteriophages must parasitize within live bacteria and have strict host specificity, which depends on the molecular structure and complementarity of phage adsorption organs and receptors on the surface of the receptor. Bacteriophages are the most prevalent and widespread group of viruses.

Bacteriophage is a general term for viruses that infect microorganisms such as bacteria, fungi, algae, actinomycetes or spirochetes.

As a type of virus, bacteriophages have some of the characteristics of viruses: tiny individuals; does not have an intact cellular structure; Contains only a single missed nucleic acid. It can be thought of as a creature that "preys" on bacteria.

The exact answer: RNA or DNA

We all know that in the current situation, human science and technology are relatively developed, but even so, in our daily life, there are many viruses, and most of the viruses will cause great harm to our human body, and we will often learn about bacteriophages in biology, so some people have proposed,If a bacteriophage is transformed into a virophage by genetic means, can a military body be transformed into a "virophage" by genetic means? The answer, of course, is no.

Although the current construction of human beings in the gene is relatively large, but there are many laws in nature, which are difficult for human beings to change, and the bacteriophage is like this, as a member of the virus, the phage naturally also has the characteristics of the virus, the virus can not be called a cell, because the virus survives by absorbing the host's nutrients, once it leaves the host, then the virus will soon die, and this characteristic of the virus is caused by its own material composition and structure, but at present, Human beings are not able to change this situation, so it is impossible to use genetic means, and the phage will be transformed into a virophage.

In 2019, the new crown epidemic that broke out in the world was caused by the new coronavirus, and the new crown virus also absorbs human nutrients to maintain its own survival, but the more this is the case, the greater the harm to the human body, and human beings cannot use genetic means to change the characteristics of the new coronavirus, so now the world is facing the new coronavirus, the danger of existence, but from this example, we can also see that genetic means cannot change the characteristics of the virus.

Therefore, no matter what virus it is, in the current research methods of human genes, the modification of genes is the modification of the ordered fragments of DNA, although today's medical technology is also very developedHowever, it cannot change the fact that at present, even with the use of genetic technology, human beings cannot modify bacteriophages into viriophages.

When phage DNA is replicated, the product of bacterial DNA decomposition is used as raw material - (excerpt from "Introduction") But I learned a little more, phages are divided into mild phages and virulent phages Copy a passage here:

Virulent bacteriophages refer to phages that can continuously complete the five stages of adsorption, invasion, proliferation, assembly and lysis in a short period of time to achieve their reproduction. After the virulent phage enters the bacterium, it changes the nature of the host, making it a factory for the manufacture of bacteriophages, and produces new phages in large quantities, which finally leads to the death of the pythagocytosis.

Mild phage refers to a phage that only integrates on the host's nuclear chromosome set after adsorbing and invading the cell, and can replicate synchronously with the replication of the host DNA for a long time, so it does not proliferate and cause host cell lysis under normal circumstances.

In other words, the DNA of the bacteria may have been disassembled, or it may have been integrated into the DNA of the bacteriophage......Both are ...... exist

It should be broken down into nucleotides that are absorbed.

The DNA of the bacteria itself is still there, and the phages integrate their own DNA into it.

The phage genome integrated on the bacterial chromosomes is called (a)a prephage.

b Toxic bacteriophage.

c Lysogenic bacteria.

d Lysogenic state.

e Mild bacteriophage.
