Karobi Moitra is an Assistant Professor of Molecular Biology at Trinity Washington University in Washington DC. She received her PhD in 2008 and has over 13 years of teaching experience. At Trinity, she teaches a variety of biology courses from introductory genetics to cell and molecular biology. In her teaching, she emphasizes storytelling to engage students and help them learn challenging scientific concepts. She incorporates multimedia, activities, and opportunities for discussion. Her research focuses on genome annotation and its application to undergraduate research projects. She also works to incorporate teaching excellence into her tenure portfolio.
The document discusses the journey of modern humans out of Africa from around 60,000 years ago based on genetic evidence. It describes how DNA markers on the Y chromosome and mitochondria can be traced back to populations in Africa, such as the San Bushmen in Botswana. These genetic markers were then mapped as people migrated through Central Asia, Siberia, Beringia into North America, and eventually all the way to the southern tip of South America over tens of thousands of years. The document examines how human populations adapted to different environments along the way and discusses the genetic connections between all living people today.
A karyotype is the set of chromosomes in an individual analyzed from cells obtained through amniocentesis, a procedure used to obtain fetal cells from pregnant women over 35 or who previously had a child with chromosomal defects. A karyotype can determine the sex of an individual and identify chromosomal mutations like monosomy, trisomy, or deletions that can indicate disorders depending on the chromosome affected.

This document provides an overview of karyotyping, chromosome banding, and chromosome painting techniques. It discusses how karyotyping involves arranging chromosomes based on size and centromere position. Different banding techniques like Q, G, N, and C banding stain chromosomes to reveal structural features. Chromosome painting uses fluorescent probes to identify chromosomes and chromosomal abnormalities. These techniques allow studying chromosome structure, identifying defects, and analyzing evolutionary changes.
