In higher mammals like humans, the only time that two organisms naturally share the exact same DNA is when they are identical twins. Identical twins are rare, only occurring if a single fertilized egg splits apart right when it begins to grow. Cloning is a technique in which scientists artificially replicate this, producing offspring identical to the parent or another organism. It's a difficult process, but cloning is one of several ways that scientists are now using our knowledge of DNA to engineer new characteristics into organisms, by adding to or changing DNA strands. Through this genetic engineering, scientists have produced plants that create their own insecticides and body cells that glow in the dark to help locate diseased tissue. By altering the sequence and types of DNA molecules in a fertilized cell, it may someday be possible to grow new body parts to replace those that have been damaged in an accident or by cancer.

you know they are heterozygous for a trait because they have it as jj or jj.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
