Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living
Premium Protein Meiosis Chromosome
Chapter 12 Cyclins and cyclin-dependent kinases are regulatory proteins that assist in the cell cycle. Particular protein kinases give the go-ahead signals at G1 and G2 checkpoints. These protein kinases are present at a constant concentration in the cell but are inactive unless in the presence of cyclin‚ these are cyclin dependent kinases. The activity of a cdk rises and falls with the concentration of cyclin. Cyclin levels rise during the S and G2 phases then fall abruptly in the M phase

Reproduction Research Assignment Sac 5 PART 1 : Asexual vs. Sexual Reproduction [ 4 marks ] - Discuss the differences between‚ and the advantages and disadvantages of sexual and asexual reproduction : SEXUAL REPRODUCTION Sexual Reproduction is the formation of a new organism from two parents usually‚ and involves the joining of gametes [ e.g. sperm‚ pollen‚ egg] to form a single cell called a zygote [ or fertilised egg ]. The offspring are similar‚ but not identical to the parents. Sexually Reproductive
