Messenger RNA Processing May 3 2010
Description
The process of mRNA processing following DNA transcription is a critical stage of gene expression in eukaryotic cells. This explanation demonstrates how the primary transcript undergoes structural modifications, including the addition of a 5' cap and a poly-A tail. This occurs alongside the splicing process, in which non-coding introns are removed, leaving behind the protein-coding exons.
Original title
עיבוד רנ"א שליח (3 במאי 2010)
תהליך עיבוד ה-mRNA לאחר השעתוק מה-DNA הוא שלב קריטי בביטוי גנים בתאים איקריוטיים. הסבר זה מציג כיצד הגדיל הראשוני עובר שינויים מבניים הכוללים הוספת "כובע" וזנב פולי-A, לצד תהליך השחבור שבו מוסרים האקסטרונים ונותרים האקסונים המקודדים לחלבון.

Daniel Asks: Why Are We Afraid of the Dark
Credit: מכון דוידסון לחינוך מדעיThe fear of the dark is an ancient evolutionary survival mechanism designed to protect us from predators lurking in places we cannot see. Our brains tend to fill in missing visual information with our imagination, which triggers a sense of danger and anxiety in children and adults alike. Understanding the evolutionary roots of this fear helps us confront it in a more rational and calming manner.2:48

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
