A mutagen is a substance that CAUSES a mutation. Essentially, mutagens are the cause, mutations are the effect. Simple as that :)
Both nonsense and missense mutations are point mutations - meaning a single base has been substituted. The difference between the two is that a missense mutation results in an amino acid being replaced with a different amino acid, whereas a nonsense mutation results in a premature stop codon.
a beneficial mutation in an animal, plant, cell or bacteria will allow it to have a better chance of survival and allow it to continue passing on its DNA in its offspring. a harmful mutation does the exact opposite it hinders the animals survival and will eventually lead it's species to extinction.
Missense mutation: changes one sense codon to another, resulting in incorporation of amino acid.Nonsense mutation: changes a sense codon into a stop (or nonsense) codon, resulting in premature termination.
Difference between collenchyma and chlorenchyma
mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species.
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
Congenital happens before birth, acquired after.
Congenital diseases are passed genetically from a parent to an off-spring .These are acquired by birth.Acquired diseases are not passed genetically .they are acquired after birth.

a gene is passed on from generations and a chromosome is just found in certain cells
The main difference between rationalism and empiricism is that rationalism believes that knowledge is acquired through reason and logic, while empiricism believes that knowledge is acquired through sensory experience and observation.
A Chromosome is a threadlike linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information. It is a circular strand of DNA in bacteria that contains the hereditary information necessary for cell life.As appose to a Gene A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
The main difference between a motor tic and compulsion is that one is that a motor tic is involuntary and a compulsion is not. A compulsion is more of a learned or hereditary behavior.
Mutation Rate
Hereditary defects are passed down through genes from one generation to the next, while environmental defects are caused by factors in the external environment such as exposure to toxins, radiation, or infections. Hereditary defects are usually present at birth and can affect multiple family members, while environmental defects may develop later in life due to specific environmental exposures.
