It's likely you've heard some controversy about whether GMO foods are good for us. Some people systematically avoid them, assuming they are unsafe because people messed with the genes of the organism. You certainly may choose to avoid them to be 'better safe than sorry,' but just because some person changed the genes of a plant, doesn't automatically make it bad for you. The jury is still out until more studies have been completed.

In agriculture, scientists genetically modify organisms to yield more food, to fend off insects, or be more drought resistant.

Genetically modified chickens
An organism, plant or animal, is genetically modified if a scientist adds, removes, or substitutes part of the genetic code for the organism. Once this is done, the organism will pass the new genetic code down to its offspring. Genes from different organisms can even be combined.

Genetically modified chickens are much larger at a certain age now, than their non-genetically modified counterparts. The advantage is more meat, but at what cost? If a chicken cannot stand up because its little legs are too small to hold its enormous muscle mass, is that okay? This is the basis for 'bioethics,' the determination of what is acceptable by a society in regards to living things.

Before you think that genetically modifying organisms is all bad, consider this. If you know people with diabetes who are insulin dependent, or takes shots to control their blood sugar, they need genetic engineering to live. Bacteria have been genetically modified to produce human insulin for those who need it.

The gray blob is "DNA polymerase." It is adding nucleotides (A-T C-G) to the strand of DNA, so that it is double-stranded. We could say that DNA polymerase 'synthesizes' DNA.

A ribosome is an organelle, or cell part. It is made up of rRNA (ribosomal RNA) and proteins. It is actually responsible for protein synthesis. What is protein synthesis? Note - this organelle is found in both prokaryotes and eukaryotes. The rest of the organelles are only found in eukaryotic cells.
