AI Thread Summary
DNA-binding proteins recognize specific DNA sequences primarily through structural motifs that allow stable binding to DNA. These proteins often contain alpha helices and other structural elements that fit into the major and minor grooves of the DNA helix, enabling precise interaction with the base pairs. The sequence recognition occurs through a combination of hydrogen bonding, van der Waals forces, and electrostatic interactions between the protein and the DNA bases. This specificity is crucial for the regulation of gene expression and other cellular processes. For a deeper understanding of protein-DNA interactions, particularly in the context of transcription factors, further exploration of relevant literature and resources is recommended.

In general how do DNA-Binding proteins bind to DNA? Many DNA-binding proteins bind to specific sequences of DNA bases. How do the proteins accomplish this sequence recognition.

My answer: In general, DNA binding proteins possesses certain structural motifs, such as helixes, which enable them to stably bind to both double and single, stranded DNA.

How would I answer how they accomplish this sequence recognition? thanks

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
