What Is True Virus?

All true viruses contain nucleic acid—either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid)—and protein. The nucleic acid encodes the genetic information unique for each virus. The infective, extracellular (outside the cell) form of a virus is called the virion.

What are hybrid attacks Mcq?

Explanation – Hybrid attacks do crack passwords that are created with replaced characters of dictionary type words.

What do you mean by virion?

virion, an entire virus particle, consisting of an outer protein shell called a capsid and an inner core of nucleic acid (either ribonucleic or deoxyribonucleic acid—RNA or DNA). The core confers infectivity, and the capsid provides specificity to the virus.

How many viruses are in the human body?

380 trillion viruses

What is the difference between a Trojan and a virus Mcq?

1. A Virus is a malicious executable code attached to another executable file which can be harmless or can modify or delete data. Trojan Horse is a form of malware that capture some important information about a computer system or a computer network.

What is computer virus by Brainly?

A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.

Which is the smallest virus?

For the first time – scientists have detected one of the smallest known viruses, known as MS2. They can even measure its size – about 27 nanometers. For comparison's sake, about four thousand MS2 viruses lined side-by-side are equal to the width of an average strand of human hair.

Which of the following is the first computer virus Mcq?

(c) Elk Cloner is the first computer virus created by Richard Skrenta.

What is true virus?

All true viruses contain nucleic acid—either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid)—and protein. The nucleic acid encodes the genetic information unique for each virus. The infective, extracellular (outside the cell) form of a virus is called the virion.

What is Mcq virus computer?

Explanation: A computer virus is a malicious code which self-replicates by copying itself to other programs. The computer virus gets spread by itself into other executable code or documents. The intention of creating a virus is to infect vulnerable systems.

Who invented virus Mcq?

Clarification: Dmitri Iwanowski, in the year 1892, discovered the viruses. He found the causal agent of mosaic disease of the tobacco plant which caused the discoloration of the leaf. He was one of the founders of virology.

Where did viruses come from?

Viruses may have arisen from mobile genetic elements that gained the ability to move between cells. They may be descendants of previously free-living organisms that adapted a parasitic replication strategy. Perhaps viruses existed before, and led to the evolution of, cellular life.

Which is largest virus Mcq?

The largest virus is the pox virus, around 250 to 300 microns. The infectious viral particles have the enzymes required for replication within the virion and hence, the virus has a large size. These viruses are different from other viruses in their ability to replicate inside the infected cytoplasm independently.

Why is nucleic acid the most important biomolecule?

Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.

Which biomolecules does not provide energy for an organism?

Nucleic acids do not provide the bulk energy for an organism, so they are not nutrients.

What are the 4 criteria for life?

Terms in this set (4)

All life forms contain deoxyribonucleic acid. All life forms have a method by which they extract energy from their surrounding and convert it into energy that sustains them. All life forms can sense changes in their surroundings and respond to them. All life forms reproduce.

What is an example of a biomolecule?

Biomolecules include amino acids, lipids, carbohydrates, proteins, polysaccharides, and nucleic acids.

How are chromosomes different than genes?

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

What is virus Slideshare?

WHAT IS A VIRUS? Viruses may be defined as acellular organisms whose genomes consist of nucleic acid, and which obligately replicate inside host cells using host metabolic machinery to different extents, to form a pool of components which assemble into particles called virions .

Is DNA a macromolecule?

Introduction. Nucleic acids, and DNA in particular, are key macromolecules for the continuity of life.

What is a molecular laboratory?

The Molecular Diagnostics Laboratory is responsible for the development and performance of molecular diagnostic tests for nucleic acid targets found in a variety of settings in medicine.
