Tues-Day 1
Bio 3/6- we discussed gene regulation, that is the influence of the environment on genetic "expression". A trait that is coded for by a gene will not be expressed/be seen if the gene is "turned off" due to particular environmental factors i.e. temperature, light intensity, glucose level, pH, etc.
We also defined the term allele, which is the same as a gene but is just a more specific term. An allele is a specific version of a given gene i.e. the gene for blood type has at least three different alleles: A, B, and O. The gene for the number of digits on your hand has the five-finger allele and the six-finger allele.
We then did a transcription and transcription activity that compares the hemoglobin made from the normal gene and the sickle cell gene.
AP Chem- we further discussed the Bohr model of the atom, explaining the meaning/factors influencing the principal energy level of an electron equation. We explained how the bright line emission spectrum is formed.
We reviewed the meaning of the wave and particle nature of light and drew pictures associated with each term.
We then expanded Bohr's equation for any one electron element (typically ions) and explained why Bohr's model fails for multi-electron systems.
