Be able to explain the processes of DNA replication, transcription and translation. https://www.youtube.com/watch?v=gG7uCskUOrA. Replication. DNA makes an exact copy of itself. Unzips. DNA polymerase unzips the DNA by breaking the weak hydrogen bonds that hold nitrogen bases together.

If there are 34% of Adenines in DNA, what is the percentage of . uracil. in RNA?. 34%. 2. .   . Replicate. the following segment of DNA:.     5’- ATCGGCTACGTTCAC  -3’. Chapters 12 & 13. The Role of dna. Stores Information. Keeps the instructions that make you look and act the way you do. Copies Information. During cell division you have to copy the DNA before the cell can split. Before a cell can divide, the DNA in the nucleus of the cell must be duplicated. . Since the DNA molecule consists of two complimentary stands, if those two strands separate and the right conditions are present, two new stands that are the compliments of the originals will be produced..

Mutations. Chargaff's rule. states DNA of any species contains equal amounts of guanine and cytosine and also equal amounts of adenine and thymine. . This pattern is found in both strands of the DNA. . They were discovered by Austrian chemist Erwin Chargaff. Griffith finds a ‘transforming principle.’ . Griffith experimented with the bacteria that cause pneumonia.. He used two forms: the S form (deadly) and the R form (not deadly).. A transforming material passed from dead S bacteria to live R bacteria, making them deadly.. 1. Each . organism has a unique combination of characteristics encoded in molecules of . ________. DNA. 2. Molecules . of DNA are composed of long chains . of _______. NUCLEOTIDES. 3. ____ built . models of DNA that demonstrated the double helix is held together by H bonds.
