relationships between reproduction‚ heredity and DNA. Genetics – From Genes to Proteins‚ Mutations During transcription‚ the information in the DNA of a specific gene is copied into mRNA (messenger RNA)‚ which creates a nucleotide sequence. After transcription‚ if the DNA base sequence is 3’-TACCCTTTAGTAGCCACT-5’‚ then the base sequence of mRNA would be 5 ’-AUGGGAAAUCAUCGGUGA-3’. During translation‚ Ribosomal RNA combines with proteins to form a ribosome. tRNA (transfer RNA) brings individual amino

Like cement sets the foundation for a house‚ the cell theory sets the foundation for biology. Schleiden and Schwann proposed the cell theory‚ which states that the cell is the basic unit of life and that new cells arise only from the reproduction of already existing cells via cell cycle‚ in 1839. Since the cell is the structural and functional unit of life as the house is for a community‚ without the house the community would be irritated and would not be stable‚ the community would therefore cease

Unit 2 Lecture Study Guide – 1) What are the parts of an atom? Where are the subatomic particles found? a) Protons‚ neutrons‚ and electrons b) Protons and neutrons are located in the center of an atom in the nucleus and the electrons are located around the nucleus. 2) How does the Atomic Mass # differ from the Atomic #? The atomic mass number is the sum of the number of protons and neutrons in the nucleus of an element and the atomic number is the number of protons that it has. 3)

The mTOR Pathway Introduction The mammalian target of rapamycin (mTOR) signaling pathway integrates both intracellular and extracellular signals and serves as a central regulator of cell metabolism‚ growth‚ proliferation and survival. Discoveries that have been made over the last decade show that the mTOR pathway is activated during various cellular processes (e.g. tumor formation‚ insulin resistance‚ adipogenesis and T-lymphocyte activation) and is deregulated in human diseases such as cancer
