I was trying to tag my fiancee in a picture and as I clicked post, I was directed to a page on Instagram that told me to put in my phone number for a security verify. The only problem is... I don't have a cell phone.
Point mutations in the coding region of DNA can have one of three consequences: 1) No effect if the mutated codon still codes for the same amino acid. 2) It can result in the protein having one different amino acid. The effect on protein function can vary from no effect to devastating diseases such as cycstic fibrosis.
Mutation is a change in the nucleotide sequence of a gene or a chromosome. Based on the effect of mutation on the gene structure, mutations may be: (1) small-scale mutations or (2) large scale mutations. Small-scale mutations are a type of mutation where one or few nucleotides of a gene are affected. They are further classified as follows: (1) substitution mutations, (2) insertion mutations, and (3) deletion mutations. Insertion mutations are a type of mutation wherein one or more nucleotide base pairs are inserted to a chromosome or a DNA sequence.
