DNA Structure & Replication - Weebly
about DNA Replication. Complete the diagram to the right. Provide all missing bases and also label any missing 3’ or 5’ ends of DNA. 21. DNA Polymerase is the name of the enzyme that reads old DNA and lays down new DNA. 22. This enzyme reads template DNA from 3’ to 5’. 23. The enzyme then lays down new DNA from 5’ to 3’. 24.

Evolution by Natural Selection - Weebly
www.badgerapbiology.weebly.comEvolution by natural selection takes place over many, many generations. Evolution by natural selection leads to adaptation within a population. The term evolution by natural selection does not refer to individuals changing, only to changes in the frequency of adaptive characteristics in the population as a whole.

Application of Genetic Engineering
epgp.inflibnet.ac.ininvolves different techniques to insert, alter, or cut out pieces of DNA that contain one or more genes of interest. This is also known as genetic modification, gene transfer or transgenesis. Doing this is possible because DNA is like a universal language; all DNA for all organisms is made up of the same nucleotide building blocks.
