Point mutation : a mutation affecting only one or very few nucleotides in a gene sequence

silent mutation : Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype.

missense mutation : In genetics, a missense mutation is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid

nonsense mutation : a mutation in which a sense codon that corresponds to one of the twenty amino acids specified by the genetic code is changed to a chain-terminating codon.

chromosomal mutation : Chromosome mutation is the process of change that results in rearranged chromosome parts, abnormal numbers of individual chromosomes, or abnormal numbers of chromosome sets.

frameshift mutation : A frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three

duplication : Duplication is a type of mutation that involves the production of one or more copies of a gene or region of a chromosome

insertion : In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping.

gene mutation : A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.

deletion : Deletion is a type of mutation involving the loss of genetic material. It can be small, involving a single missing DNA base pair, or large, involving a piece of a chromosome.

could be wrong on some , hope this helps tho !

Answer from: mv603177

Explanation:

A point (substition) mutation is when one base is substituted for another. A silent mutation is a type of point mutation. It is when one base is substituted for another but the amino acid does not change. The new codon that is made from the substitution still codes for the same amino acid as the original codon was suppose to. The protein made is still functional. A missense mutation is also a type of point mutation. It is when a one base is substituted for another causing the amino acid to change. It creates a nonfunctional, truncated protein. A nonsense mutation is the last kind of point mutation. It is when one base is substituted for another and the new codon made codes for a STOP amino acid. This makes a nonfunctional, truncated protein. A frame shift mutation is when the entire reading frame if the DNA sequence is changed. The two types of frame shift mutations are deletion and insertion. Deletion is when one nucleotide is taken away, or deleted from the DNA sequence. This will make a nonfunctional protein. Insertion is when a nucleotide is added to the DNA sequence. It makes a nonfunctional protein. Missense and nonsense mutations can also be frameshift mutations, but never silent. A chromosomal mutation occurs when the sister chromatids or homologous chromosomes fail to separate. Duplication is a type of chromosomal mutation where one chromosome have two copies of a gene or genes and the other no copies.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
