Cytoplasmic factors play a significant part in determining how a cell develops. This segment discusses their importance in turning the appropriate genes on and off for proper development.
An overview of embryonic development, the progressive differentiation of cells, and properties of embryonic stem cells.
To accompany the lecture series Evolution: Constant Change and Common Threads.
... but that's not all they'll do. Several genes determine the diverse shapes and functions of crustacean appendages.
Chromosomes change form as a cell divides to ensure that each daughter cell gets a full, intact copy of the genome.
The poster from the 2006 Holiday Lectures on Science, Potent Biology: Stem Cells, Cloning, and Regeneration, illustrates the role of stem cells during human embryonic development.
