Molecular biology fills gaps in knowledge of bat evolution

This observation led to the original hypothesis that JIP1 acts as a cytoplasmic anchor for JNK.JIP1 has been shown to bind selectively to JNK but not to the ERK or p38 MAP kinases; it has also demonstrated selectivity in its binding to specific proteins of the JNK pathway. In addition to JNK, JIP1...hypothesis at Biology Technology

The research was based on the hypothesis that the genome contains "hotspots" that are prone to instability and flanked on each side by large, repetitive regions of DNA, termed "segmental duplications." It is because of the repetitive nature of these regions that, during replication, the gen...... As the game progressed they had to come up with a hypothesis for the cause of death.
