... information. The fact that the polypeptides are joined together only by hydrogen bonds means that they can easily be broken and the strands can separate for replication and protein synthesis which allows for information to be transferred. DNA is a large molecule therefore it can store large amounts of ... polynucleotide chain. The DNA molecule unwinds with the help of the enzyme DNA helicase, which helps break hydrogen bonds between complementary base pairs and separate the two strands. The new nucleotides in the nucleus bind with their complementary bases in each exposed chain. DNA poly...

... lives, from manufacturing and the materials we use to the structure of our DNA. The way in which we have evolved technology has meant that we have moved from having separate devices for different tasks; I have my iPod for my music, my Kindle for my books and my Gameboy for playing games. However with the idea of ephemeralisation, technology has shifted ... smartphones to do some of the leg work for us. The more immediately unnecessary pieces of information aren't stored in our brains as we are always able to Google said piece of information when it is required. In the same respect, we a...

... sequences, so insights gained by non-human genomes often lead to new knowledge about human biology. DNA Replication DNA replicates (duplicates) just before cell division. When two strands of DNA separate, each strand can be used as a template, or a "mold," to produce a complementary strand. DNA is described as "semiconservative" because its molecule has one old strand and one new strand. Before ... bits with enzymes, is used in today's automated sequencing machines. These machines decipher relatively shorts fragments about 500 bases long, but it is faster and cheaper than previously don...
