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.
But, the truth is that most mutations are not that extreme. In biology, a mutation is any change in the nucleotide sequence of DNA. Some mutations affect large sections of DNA, and others only affect certain points along the DNA strand. These small, specific mutations are called point mutations.
