Discussion Question 1
In molecular biology and genetics, mutations are accidental changes in a genomic sequence of DNA. Using the Internet, research genetic mutations. On the basis of your research, respond to the following:Define a genetic mutation.
Genetic mutations are accidental stable and inherited changes in a gene that cause an alteration in genomic sequences and gene encoding. These mutations are the cause of genetic diseases and can be inherited and mutated genes result in natural variation
Analyze and describe the different types of genetic mutations and their effects. Then discuss, in detail, the role played by DNA and RNA in genetic diseases.
Gene mutations: These arelterations in the nucleotide sequence of a gene and chemical makeup where there are two types:
* Through substitution of bases: they are alterations in the nucleotide sequence of a gene and two classes are known: transitions or transversions.
* Through loss or insertion of nucleotides: they are modifications where a nitrogen base can be lost or added, which is important to encode a specific protein and this changes the genetic material.
Chromosomal mutations: They are alterations in the gene sequence of a chromosome and structure, and there are four types
* Duplication: A repeat of a chromosome fragment.
* Deletion: Loss of a chromosome fragment
* Translocation: Change of position of a chromosome segment
* Inversion: Change of sense of a chromosome fragment.
Nonsense mutation- This is a mutation where there is a change in one of the bases of the DNA in such a ...
