Biology Tutor Specializing in Genetics, Microbiology, and Cell Biology, physiology and anatomy

The Tutor and Student reviewed the processes of transcription and translation. They discussed the enzymes involved in transcription, promoter regions, termination mechanisms, and post-transcriptional modifications. The genetic code, ribosome function, tRNA roles, and protein folding and targeting were also covered. The class concluded with a plan to review notes and potentially work on practice questions for these topics.

The session covered introductory concepts of molecular biology, including the structure and packaging of DNA, gene definition, and the composition of DNA and RNA. The Tutor guided the Student through the initial stages of DNA replication, focusing on key enzymes and the process of strand separation and primer synthesis. The next class will continue with transcription and translation.

The student and tutor worked through problems related to dihybrid crosses in genetics, focusing on constructing Punnett squares, determining phenotypic and genotypic ratios, and calculating probabilities of specific offspring traits. They practiced identifying dominant and recessive alleles and their combinations, confirming the 9:3:3:1 phenotypic ratio and exploring variations in crosses.

The Tutor and Student reviewed key concepts in Geology, including plate tectonics, mineral formation, and mineral properties. They discussed different types of plate boundaries, the origin of ores like banded iron formations, and various characteristics used to identify minerals such as hardness and cleavage. The next steps involve the student providing further details for future review sessions.

The tutor and student reviewed and practiced genetics concepts including monohybrid crosses, chromosomal disorders (Down, Turner, Klinefelter syndromes), and Mendel's laws of segregation and independent assortment. They worked through practice problems and discussed scheduling for future sessions, with a plan to cover dihybrid crosses and other genetic concepts.

The Tutor and Student reviewed non-Mendelian genetics, including concepts like incomplete dominance, pleiotropy, epistasis, and sex-linked inheritance with a focus on hemophilia. They then practiced solving genetics problems through multiple-choice questions, reinforcing concepts such as independent assortment and test crosses. The next session is scheduled for Friday.
