*phospholipid bilayers) of almost every cell in the body (red blood cells being an exception). DNA (your genotype) is double stranded and is responsible for replicating (from 46 to 92) during Interphase‚ so that mitosis can make new cells‚ repairing and allowing for growth in the body. It is also responsible for transcription and translation‚ a series of processes that allows for the genotype to become a phenotype (what you look like and metabolic processes). DNA is ~ 2 M long‚ and yet fits into a cell that

Genes Review 1) Selective breeding – chosen based on what can be seen and detected (favourable phenotype) Genetic engineering – selected based on genes 2) - DNA are found in nucleus (where most DNA are found)‚ mitochondria‚ chloroplast 3) - Translation requires ribosome‚ mRNA‚ tRNA (anticodon) and amino acids - DNA template‚ polymerase for transcription 4) Mitosis generates daughter cells that are identical Meiosis – homologous recombination 5) DNA coding sequence: 5` GGGCCCTTTAAA

Eusociality Research Proposal Project Objectives The objective of this research is to aid in identifying how honey bees‚ Apis mellifera‚ and potentially all eusocial insects‚ have evolved to their current level of social organization‚ . By studying the behavior of the worker caste in the absence of the queen‚ we will be able to see signs of whether these organisms have evolved from kin selection or multilevel selection. The ultimate goal is to see if worker bees can thrive and manage a colony
