Short answer questions – generally complex by their nature and require knowledge and integration of several different concepts 1. Explain what are the end goals of reproductive cloning and therapeutic cloning. Outline the steps both procedures share and the step(s) specific for each procedure. • Reproductive Cloning- Reproductive cloning is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. It is accomplished using a process called somatic cell

Mabolo (Diospyros blancoi) Velvet Apple A member of the Ebenaceae family‚ mabolo is known for its value as an ornament‚ rather than for its fruit. Its wood is commonly known in the Philippines as kamagong‚ and it is the fruit that goes by the name of mabolo. It is an evergreen forest tree that is medium-sized‚ and has an oval or conical-shaped crown. Depending on the way it was planted‚ a mabolo tree may have long‚ straight stems or short trunks. Its leaves are oblong-shaped‚ which are big and

Overview: Nylon is a thermoplastic silky material‚ first used commercially in a nylon-bristled toothbrush (1938)‚ followed more famously by women’s stockings ("nylons"; 1940). It is made of repeating units linked by amide bonds and is frequently referred to as polyamide (PA). Nylon was the first commercially successful synthetic polymer. There are two common methods of making nylon for fiber applications. In one approach‚ molecules with an acid (COOH) group on each end are reacted with molecules

Introduction : "Aromatic" and "aromatic compound" sidetrack here. For implications identified with odor‚ see fragrance compound. Two distinctive reverberation types of benzene (top) consolidate to create a normal structure (base) In natural science‚ the term aromaticity is utilized to depict a cyclic (ring-molded)‚ planar (level) particle that shows strange dependability when contrasted with other geometric or connective game plans of the same arrangement of iotas. As an aftereffect of their security

The tert-butyl group has been broadly used to protect functional groups in natural product synthesis such as amino acid‚ peptide and protein chemistry [1]. The tert-butoxycarbonyl (BOC) group is known as protecting group for amides in organic synthesis. The introduction of BOC group improves the solubility of organic precursors and their processability in organic synthesizes [2]. The methyl substituted pyridine derivatives were widely reported for their various biological activities such as anxiolytic

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans‚ trans-1‚5-Diphenyl-1‚4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol tautomerization is an equilibrium process that produces little of the enol (ppm or less). However‚ any enol that formed quickly reacted
