Yeah rita...I had some learning of the topic named dna mutations.It was very interesting rita..Shall we discuss about it for sometie?
Ok lets have some discussion about dna mutations.Mutations are a change in rna or dna. It results from dna copying mistake made during dna copying , exposure to chemicals.
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed.
Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene's instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.
A point mutation is a change in a single nucleotide in DNA. This type of mutation is usually less serious than a chromosomal alteration. An example of a point mutation is a mutation that changes the codon UUU to the codon UCU. Point mutations can be silent, missense, or nonsense mutations
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.
Duplication is a type of mutation that involves the production of one or more copies of a gene or region of a chromosome.
An inversion occurs when a chromosome breaks in two places; the resulting piece of DNA is reversed and re-inserted into the chromosome.
Substitution is a type of mutation where one base pair is replaced by a different base pair. A translocation occurs when a piece of one chromosome breaks off and attaches to another chromosome.
It was very pleasure to discuss this topic with you Josh . Ok i've to leave now.Bye josh.
It was a Nice discussion with you rita.Take care and bye.
