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.
DNA methylation may affect the transcription of genes in two ways. First, the methylation of DNA itself may physically impede the binding of transcriptional proteins to the gene, and second, and likely more important, methylated DNA may be bound by proteins known as methyl-CpG-binding domain proteins (MBDs).
