BIOL-321HG Advanced Topics in Biological Sciences: 'Molecular Genetics and Human Genetic Disorders'

Not Scheduled for This Year. Credits: 4

Mendel's principles of genetic inheritance underpin all the inheritance patterns that we observe and the traits they govern. However, in nature, not all is as it first appears. Many traits seem to diverge from Mendelian genetics until we understand those inheritance patterns more deeply. In this course, we will explore the depths of genetic inheritance by first understanding the mechanisms of these seeming "exceptions of Mendelian inheritance". We will then understand how the molecule of DNA behaves in the nucleus to allow for gene expression and how we study DNA in the lab. Finally, we will discuss human genetic disorders that occur because of deviations in gene expression or DNA behavior but are rooted in Mendelian genetic principles. The capstone experience of the course is a student-group project exploring experimental approaches for diagnosing or treating a human genetic disorder.

Lectures will be centered on primary scientific literature and topics relating local hydrology, biogeochemistry, and species and community interactions, within a context of human impacts and climate change. Lab sections will be field- and laboratory-based, including methodologies for sample collection in campus streams, species identification and observation, and water quality assessment. The course will also engage regional stakeholders, natural resource managers, and academic experts to connect foundational ecological principles with applied watershed conservation and management. Final group research projects will apply course knowledge and skills, with student presentations focused on reporting results from their experimental, research, or stakeholder engagement based findings.

Applies to requirement(s): Math Sciences
Prereq: 8 credits at the 200-level in Biological Sciences.

BIOL-352 Molecular Ecology

Not Scheduled for This Year. Credits: 4

Over the past quarter century, molecular genetic methods have become increasingly important in ecological research. In this course, we will examine contemporary molecular genetic tools and learn how they can be used to answer ecological questions. Topics will include: reconstruction of ancestral relationships; measuring the size, diversity, and spatial structure of populations; characterization of migration and dispersal patterns; and identification of sensitive or threatened species and populations. We will explore these themes through foundational texts and current scientific literature, and we will analyze molecular genetic datasets in class to gain familiarity with available techniques.

Applies to requirement(s): Math Sciences
Other Attribute(s): Speaking-Intensive, Writing-Intensive
Prereq: BIOL-210 or BIOL-220, and BIOL-223 or BIOL-226.

BIOL-353 Pregnancy and the Placenta

Fall. Credits: 4

Pregnancy is a stunning feat of physiology. It is a conversation between two bodies -- parental and fetal -- whose collective action blurs the very boundaries of the individual. In this course we will explore such questions as: what is pregnancy, and how does the ephemeral, essential organ known as the placenta call pregnancy into being? How is pregnancy sustained? How does it end? We will consider the anatomy of reproductive systems and the hormonal language of reproduction. We will investigate the nature of "sex" hormones, consider racial disparities in pregnancy outcome, and weigh the evidence that the intrauterine environment influences disease susceptibility long after birth.

Crosslisted as: GNDST-333PC
Applies to requirement(s): Math Sciences
Other Attribute(s): Speaking-Intensive
Restrictions: This course is open to juniors and seniors
Prereq: 8 credits at the 200 level in Biological Sciences.

BIOL-354 Race and Biology

Not Scheduled for This Year. Credits: 4

In this student-centered, discussion-based seminar, we will explore current hypotheses about the evolution of human variation, trace the history of how biology has been used in the construction of racial ideologies, and delve into the impacts of racial categorization on human health. We will investigate these themes through readings, videos, class discussions, student expert panels, and research papers. Students taking this course will improve their ability to: engage constructively in scholarly discussions; use verbal and written discourse to explore themes in science; use new knowledge to understand current issues; critically evaluate media information using evidence from scientific studies; and communicate new knowledge.

Applies to requirement(s): Math Sciences
Prereq: 4 credits at the 200-level in Biological Sciences.

BIOL-395 Independent Study

Fall and Spring. Credits: 1 - 8

In this class, students will acquire hands-on experience in diverse aspects of the research process in a field of Biology, from familiarizing themselves with a research topic, generating interesting questions, designing experiments, acquiring technical skills, collecting and analyzing data, to writing and/or presenting their results. Spots are limited. Interested students should submit the departmental research application, which typically opens each semester ahead of the academic advising period. Faculty review applications after the deadline and inform students prior to the start of the following semester. A single credit requires an average of 3 hours of work per week. (Note: Some faculty may require a set weekly meeting time for a portion of this class.)

Restrictions: Contact instructor for independent study declaration form and signatures.
Instructor permission required.
Notes: See safety training restrictions in description of BIOL-295.

BIOL-399 Biology Journal Club/Data Hub

Not Scheduled for This Year. Credits: 1

Reading and understanding research reports from the primary scientific literature is an essential skill for any scientist. Likewise, critiquing experimental proposals and freshly-minted data is one of the core components of the pursuit of science. Using the Biology Department Seminar series as a springboard, this course seeks to familiarize students with the process of understanding, appreciating, and critiquing scientific manuscripts. Additionally, drawing on projects being proposed and executed under the auspices of BIOL-395, this course seeks to help students develop comfort discussing "fresh" scientific data. This course will provide a valuable way to connect with active scientists, both developing and experienced, from within and beyond Mount Holyoke.

Applies to requirement(s): Meets No Distribution Requirement
Prereq: 8 credits in Biological Sciences.
Notes: Repeatable for credit. Credit/no credit grading only. Reading materials will be drawn primarily from research and review articles in the primary scientific literature. Data will be presented by students actively engaged in research projects. We will discuss data and readings as a group in class meetings.
