Question

4. In mitosis, it can sometimes take a long time for the chromosomes to assemble on the metaphase plate, but the cell won't begin anaphase until all of the chromosomes are lined up properly. Why do you think this is? (3 pts) 5. Below is a photo of a gel from the ant PCR lab. Lanes are labeled with the genus of ant (C for Camponotus and T for Tetramorium) and the gene that was amplified (I for Insect Bar Code and W for WSP). Last week, your friend hypothesized that both genera of ant would be infected by Wolbachia equally. Based on the results in this gel, is their hypothesis supported or not? Briefly explain how you know. (3 pts)

Explanation / Answer

ANS 4) The most critical procedure that happens amid metaphase and won't undergo anaphase until all chromosomes are aligned are spindle checkpoint where it checks the correct division of chromosomes despite the fact that the chromosomes adjust contrastingly amid mitosis and meiosis. If these checkpoints are skipped and the cell start anaphase before the chromosomes are legitimately appended to microtubules and adjusted on the metaphase plate they apparently get arranged into the wrong cells which leads to the formation of few or too many daughters cells further leading to birth abandons and non-suitable posterity, infact there are also chances that daughter cells become carcinogenic.
