A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA that determines what protein to produce and when, is called a gene. First established in 1985 by Sir ...

the presence of adenine in the DNA template strand tells RNA polymerase to attach a uracil in the corresponding area of the growing RNA strand (Figure 4). Interestingly, this base substitution is ...

all the way down to the level of the atoms that make up a single DNA base. The human body contains about 100 trillion cells, each working together in a complex symphony of interactions.
