A breakthrough study sheds new light on how brain cells relay critical information from their extremities to their nucleus, leading to the activation of genes essential for learning and memory.
After all, there must have been a time when the ancestor of eukaryotes did not possess a nucleus; the question is whether that cell possessed a mitochondrion or not.
Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...
