Engage in Interactive Physics Classes with challenging preparation and a variety of teaching approaches to suit your learning style.

The tutor and student reviewed the process of DNA replication, covering its occurrence in the S phase, the semi-conservative model, and the roles of key enzymes like helicase, primase, and DNA polymerase. They also discussed Okazaki fragments and the differences in replication between prokaryotes and eukaryotes. Further topics like topoisomerase and DNA repair were planned for the next session.

The Student and Tutor discussed mitosis, meiosis, and the cell cycle, including the various phases and key differences between the processes. The Student worked through short answer questions, and the Tutor provided a worksheet with objective and long-form questions for further practice. The Student was assigned worksheets covering nucleotides, DNA/RNA, purines/pyrimidines, mitosis/meiosis, and the cell cycle.

The Student and Tutor reviewed epigenetics, focusing on DNA methylation and acetylation, and then moved on to transcription, including the roles of promoters, enhancers, and RNA polymerase. The Student practiced converting a DNA sequence to an mRNA sequence and identifying amino acid sequences using codon charts. The Tutor assigned practice worksheets and will provide written notes, and the Student will send the updated PowerPoint for review.

The student and tutor reviewed the structure and components of nucleotides, including the bases, sugars, and phosphates. They discussed DNA's double helix structure, base pairing rules, and the significance of coding versus non-coding DNA sequences. The session concluded with a discussion of the 5' and 3' ends of DNA strands and plans to cover DNA replication and transcription in future sessions.

The Tutor and Student reviewed concepts related to mechanics, including Atwood machines, work done by forces, conservation of energy, power calculations, and spring-mass systems on inclined planes. They worked through several practice problems, with the student demonstrating understanding of calculations involving acceleration, energy, and work, and the Tutor providing explanations and formulas. The Tutor plans to send practice worksheets.

The Tutor and Student reviewed mutations, including point and frameshift types, and their effects on genetic sequences. They practiced analyzing inheritance patterns using pedigrees and identifying different types of mutations by comparing DNA and RNA sequences, with a focus on genetic disorders like sickle cell anemia.
