Gene Activity in Early DevelopmentThe new third edition of Gene Activity in Early Development reflects the ten years of technological progress since the last edition. Providing a unique blend of classical and molecular knowledge, it discusses all major embryonic systems from both a comparative and mechanistic point of view. In deriving overall interpretations of developmental phenomena, it brings into play all the disparate forms of evidence, including genetic, molecular, and cytological.**This book is written for any serious student or scholar entering the field, whether his or her background is in genetics, molecular biology, or embryology. |
