Report on Guest Lecture on Nucleic Acids

A guest lecture on “Nucleic Acids” was delivered by Dr. P. Mary Anupama to the postgraduate Chemistry students of St. Joseph's College for Women on 5th May 2026. The session aimed to provide an in-depth understanding of the chemistry, structure, and biological significance of nucleic acids, with special emphasis on the experimental proofs underlying nucleic acid structure.

The lecture began with an introduction to nucleic acids and their role as the genetic material of living organisms. Detailed explanations were provided on the structural organization of nucleotides and nucleosides. The speaker elaborated on the chemical and experimental proofs demonstrating that nitrogen bases are linked to ribose through the N9 position in purines. Hydrolysis studies, methylation experiments, X-ray crystallography, and stability analyses were discussed systematically.

Further, the session highlighted the chemical evidence supporting the furanose form of ribose and deoxyribose in nucleic acids. The lecture also explained the significance of phosphodiester linkages and the experimental proofs supporting the 3′–5′ phosphate linkage in nucleic acids. Students were introduced to the pioneering contributions of scientists such as Rosalind Franklin, Watson, Crick, and Todd in elucidating DNA structure.

A detailed description of the typical B-DNA structure was presented, including antiparallel strands, complementary base pairing, hydrogen bonding, helical dimensions, and the biological importance of major and minor grooves. The lecture successfully connected biochemical concepts with structural chemistry, helping students appreciate the molecular basis of heredity.

The session was highly interactive and informative. Students actively participated in discussions and clarified their doubts regarding nucleic acid chemistry and molecular structure. The lecture greatly enriched their conceptual understanding of advanced biomolecular chemistry topics.

Report on Capacity Building Workshop on CO-PO Mapping & Their Attainment Calculations

Date: 02-05-2026                                                                   Time: 10.00 am to 2.00 pm

A Capacity Building Workshop on “CO-PO Mapping & Their Attainment Calculations” was organized by S.G.A. Government Degree College (Autonomous), Yellamanchili, Andhra Pradesh, on 02-05-2026 at 10:00 AM in the IQAC Hall.

The workshop aimed to enhance faculty understanding of Outcome-Based Education (OBE), Course Outcomes (COs), Program Outcomes (POs), Program Specific Outcomes (PSOs), and attainment calculations used in higher education assessment and accreditation processes.

The workshop featured expert sessions by distinguished academicians from St. Joseph’s College for Women (A), Visakhapatnam.

Session I – POs and PSOs: Their Importance

Speaker: Dr. P. Rosina George

Dr. P. Rosina George, Assistant Professor in Zoology, delivered an insightful lecture on Program Outcomes (POs) and Program Specific Outcomes (PSOs). She explained their role in curriculum design, academic planning, and quality enhancement. The speaker highlighted how POs and PSOs help institutions evaluate the overall development of students in terms of knowledge, skills, and employability. She also emphasized their importance in accreditation processes such as NAAC and in maintaining academic standards through measurable learning outcomes.

Session II – CO-PO Mapping

Speaker: Dr. E. Harini

Dr. E. Harini, Selection Grade Lecturer & Head, Department of Zoology, explained the concept of Course Outcome (CO) to Program Outcome (PO) Mapping. She discussed the preparation of CO statements, correlation levels, and the systematic alignment of course objectives with program outcomes. The session provided clarity on mapping procedures and demonstrated how effective CO-PO mapping helps in assessing curriculum effectiveness and student learning achievements.

Session III – Attainment Levels and Calculations

Speaker: Dr. P. Mary Anupama

Dr. P. Mary Anupama, Head & Assistant Professor, Department of Biochemistry, delivered a detailed session on attainment levels, their calculations, importance, and inference. She explained the concepts of direct and indirect attainment methods, including the use of internal assessments, semester examinations, assignments, and student feedback. The speaker demonstrated step-by-step procedures for calculating attainment levels and interpreting the results for academic improvement.

The lecture also focused on:

• Weightage distribution in attainment calculations
• CO attainment analysis
• Interpretation of attainment data
• Importance of attainment in Outcome-Based Education and accreditation

The workshop was highly interactive and benefited faculty members by providing practical understanding of OBE practices, mapping strategies, and attainment analysis. The participants appreciated the clarity and practical orientation of the sessions. The program concluded with a vote of thanks to the management, resource persons, and participants for the successful conduct of the workshop.
