Unlocking the Mysteries of Gene Expression: From Genomic Imprinting to Non-Coding RNAs in Biology Class with Dr. Mishra #GeneExpression #BiologyClass #GenomicImprinting #NonCodingRNAs #CollaborativeLearning

Dr. Mishra: “Hello there! I see we have a new face in our biology class today. Welcome! We’re so glad you’re here, and I want you to know that this classroom is a friendly and supportive place. If you ever have questions or need assistance, don’t hesitate to ask me or your classmates. We’re all here to learn together and make this an enjoyable experience for you.” Abby: “Hello. My name is Abha…

Analyzing Chromatin Structure in More Detail Than Ever Before

Analyzing Chromatin Structure in More Detail Than Ever Before

A powerful method that can pinpoint the positions and orientations of individual nucleosomes—one of the building blocks of chromatin, which contains the genetic material of a cell—has been demonstrated on yeast by a RIKEN team1. It will help researchers to explore the relationship between chromatin structure and function.

While the molecular structure of DNA has been known for over 60 years,…

Induced Pluripotent Stem Cells - Addressing Safety Concerns

Induced Pluripotent Stem Cells – Addressing Safety Concerns

In 2012, John B. Gurdon and Shinya Yamanaka won the Nobel Prize in Physiology or Medicine “for the discovery that mature cells can be reprogrammed to become pluripotent.” Since that time, induced pluripotent stem cells (iPSCs) have largely taken the stem cell scene by storm. Because of the ease with which iPSCs can be made from just about any mature cell type, and because they can be made so more…

Pluripotent Stem Cells Actively Regulate The Openness of their Heterochromatin

Pluripotent Stem Cells Actively Regulate The Openness of their Heterochromatin

Packaging DNA into a small area like the nucleus of the cell does not occur unless that DNA is tightly wound into compact structures collectively known as chromatin. However, not all regions of the genome show the same degree of compaction. Highly-expressed regions of the genome tend to be less highly compacted and regions of the genes that are not expressed to any degree tend to be squirreled…
