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.
Effects of Mutations on DNA Sequence. There are several types of mutations that are classified according to how the DNA molecule is altered. One type, called a point mutation, affects a single base and most commonly occurs when one base is substituted or replaced by another. Mutations also result from the addition of one or more bases, known as an insertion, or the removal of one or more bases, known as a deletion.
