What is a physical or chemical agent that changes the nucleotide sequence of DNA?

In genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, such mutagens are therefore carcinogens, although not all necessarily are.

What is a substance that changes the nucleotide sequence of DNA?

A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.

What is the change in sequence of DNA?

A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base.

What type of change occurs to a nucleotide when it is activated?

Mutation, repair and recombination. (A) A mutation is a small-scale change in the nucleotide sequence of a DNA molecule. A point mutation is shown but there are several other types of mutation, as described in the text.

Which mutagen is an example of a physical agent?

The chemical or physical agents that cause mutations are called mutagens. Examples of physical mutagens are ultraviolet (UV) and gamma radiation. Radiation exerts its mutagenic effect either directly or by creating free radicals that in turn have mutagenic effects.

What is mutagen give example?

They are mainly of two types: Chemical mutagens - They include different types of chemicals that cause mutation. E.g.; EMS (Ethyl methane sulphonate). Physical mutagens - They include all types of irradiations. E.g.; gamma rays, ultraviolet rays etc.

What is the chemical and physical structure of DNA?

DNA is the chemical name for the molecule that carries genetic instructions in all living things. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

What is a physical mutagen?

Physical mutagens include electromagnetic radiation, such as gamma rays, X rays, and UV light, and particle radiation, such as fast and thermal neutrons, beta and alpha particles. Mutagenic treatment of seeds is the most convenient and, therefore, the standard method in seed propagated crops.

What are things that cause changes in the DNA sequence called?

DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation.

What are the some ways by which the nucleotide sequence can be changed?

There are three types of DNA Mutations: base substitutions, deletions and insertions.

What chemicals can alter your DNA?

In-vitro, animal, and human investigations have identified several classes of environmental chemicals that modify epigenetic marks, including metals (cadmium, arsenic, nickel, chromium, methylmercury), peroxisome proliferators (trichloroethylene, dichloroacetic acid, trichloroacetic acid), air pollutants (particulate ...

Is an alteration change in the nucleotide sequence of the genome of an organism?

In biology, a mutation is an alteration in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA.

What type of change occurs to a nucleotide when it is activated quizlet?

What type of change occurs to a nucleotide when it is activated? The potential energy of the molecule increases.

What reaction occurs between nucleotides?

Nucleotides are joined together by a Condensation Reaction between the Phosphate Group of one and the Sugar Group of another. The bond between the two monomers is called a Phosphodiester Bond.

What are activated nucleotides?

An activated nucleotide is a nucleoside 5′-monophosphate possessing a leaving group, such as imidazole, which provides sufficient energy to form higher oligonucleotides.
