Solution phase sythesis of arylbenzoxazoles - IRM LLC

Chromosomes are containers
of DNA and are important because they hold all of our DNA for us so our cells know what to do
Questions 1-5
Question 1
The Four phases in the mitosis process are:
Prophase, Metaphase, Anaphase, Telophase
Question 2
Mitosis occurs before Gap 1 and after Gap 2 in the cell cycle
Question 3
Prophase, Metaphase, and Anaphase are three phases of the cell cycle that are considered interphase
Question 4
One cell is present at the beginning of Mitosis and Two cells are present at the end of Mitosis
Question 5
5.a
18.

during what phase of the cell cycle do you think the chromosomes are replicated (copied)?

The heart of protein biosynthesis lies in the elongation cycle, with its sequential decoding of mRNA codons to assemble the useful portion of the polypeptide. Elongation can be further broken down into three phases— aminoacyl-tRNA decoding, peptide bond formation, and translocation of the new peptidyl-tRNA (Fig. 7).

Quibell, Tjohnson, in Fmoc Solid Phase Peptide Synthesis-A Practical Approach, W.C.

An experiment is described that is suitable for the early portion of the laboratory in a general chemistry course and integrates organic examples. It is the two-step synthesis of aspirin starting from oil of wintergreen. The mechanism for this synthesis provides examples of three major classes of chemical reactions: hydrolysis, condensation, and proton transfer. To understand the chemistry, the student must be able to recognize the common molecular framework shared by oil of wintergreen, salicylic acid, and aspirin and to identify the -OH and -CO2 sites where chemical changes occur. The experiment differs in three ways from traditional aspirin synthesis experiments for general chemistry. It is designed to be performed early rather than late; it starts from a naturally occurring material and requires two steps rather than one; and it utilizes FTIR spectroscopy to distinguish among oil of wintergreen starting material, salicylic acid intermediate, and aspirin product. The use of FTIR spectroscopy introduces students to a modern analytical technique that is currently used in research involving aspirin.
