A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

Tiny repeated stretches of DNA in your genome may quietly shape how your body works, how your brain develops and how you ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune ...

Methionine is an amino acid that is used to build molecules important for cell and DNA function. Meat, eggs, fish, and other foods containing protein will have some methionine in them. Amino acids ...
