Because a point mutation is the replacement of a single base with another base. Thus, if the replacement base codes for the same type amino acid, such as a hydrophobic type amino acid replacing a hydrophobic amino acid, no change to the protein coded for will occur.
If a deletion mutation occurs then the code for the protein is disrupted and the protein product is probably going to be useless to the body and may even cause a disease.
Deletion mutation results in missing a nucleotide. Substitution causes a change from one nucleotide to a different one.
Deletion is type of point mutation and it involves loss of 1 or a few nucleotides. While point mutation also includes insertion , transition etc .
They are the same.
Here's a sample nucleotide sequence:AATUGCIf there was a nucleotide deletion (let's say the "G" gets deleted), the sequence would become:AATUCIf there was a nucleotide addition/insertion (let's say a "G" was added between "T' and "U"), the sequence would become:AATGUGCThe difference is that a deletion makes the DNA shorter and an insertion makes it longer.
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.
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.

What is the deference between Insertion Point and Pointers?
The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. A circular queue is similar to the normal queue with the difference that queue is circular queue ; that is pointer rear can point to beginning of the queue when it reaches at the end of the queue. Advantage of this type of queue is that empty location let due to deletion of elements using front pointer can again be filled using rear pointer. A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion)

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
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.
a gene is passed on from generations and a chromosome is just found in certain cells
A mutagen is a substance that CAUSES a mutation. Essentially, mutagens are the cause, mutations are the effect. Simple as that :)
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
Mutation Rate
The sequence TGA-GCC-ATG-A is changed in 2 places to become TGA-GCA-CAT-GA.When one base is changed, it is called a point mutation.In this case, a GCC in the DNA has been changed to a GCA. This would mean the mRNA codon (coded for by this DNA) would change from CGG to CGU.Both of these codons code for the same amino acid - Arginine. Therefore this type of point mutation is known as a silent mutation.The extra C that appears would be called an addition mutation, which is a type of frameshift mutation.
