DNA has a double helix shape, which is like a ladder twisted into a spiral. Each step of the ladder is a pair of nucleotides.
When DNA is copied, this is called DNA replication. Briefly, the hydrogen bonds holding together paired bases are broken and the molecule is split in half: the legs of the ladder are separated. This gives two single strands. New strands are formed by matching the bases (A with T and G with C) to make the missing strands. First, an enzyme called DNA...
A section of DNA that contains instructions to make a protein is called a gene. Each gene has the sequence for at least one polypeptide. Proteins form structures, and also form enzymes. The enzymes do most of the work in cells. Proteins are made out of smaller polypeptides, which are formed of amino acids. To make a protein to do a particular job, ...
DNA was first isolated (extracted from cells) by Swiss physician Friedrich Miescher in 1869, when he was working on bacteria from the pus in surgical bandages. The molecule was found in the nucleus of the cells and so he called it nuclein. In 1928, Frederick Griffith discovered that traits of the "smooth" form of Pneumococcus could be transferred t...
DNA gets damaged a lot of times in cells which is a problem has DNA provide instructions to making proteins. But, cells have ways to fix these problems most of the time. Cells make use of special enzymes. Different enzymesfix different types of damages to DNA. The problem comes in different types: 1. One common error is base mismatch or where the b...
