Question 1: What is cell cycle? Question 2: Using a cell from your body as an example, explain the stages in cell cycle Question 3: Mention two differences between mitosis and meiosis Question 4: Daughter cells of mitosis have the same number of chromosom Describe the phases ...
The transition from mitosis (M phase) to G1 phase is controlled by complex interactions between two key components of the cell-cycle machinery, the anaphase-promoting complex or cyclosome (APC/C) and cyclin A. The APC/C is a multisubunit ubiquitin ligase that controls sister-chromatid ...

The 2nd is where mitosis slows. And the 3rd stage is ‘senescence’ where the cell stops dividing entirely. They remain alive for a while and then do a particularly disturbing thing. They commit suicide. This programmed cell death is called ‘apoptosis’. This cell life cycle occurs through...
Throughout the menstrual cycle, the endometrium thickens little by little and undergoes changes thanks to the action of the female sex hormones: estrogens and progesterone. For embryo implantation to occur, the endometrium must be receptive. This is achieved when its endometrial thickness is between ...
What is the importance of cell cycle control? Many females using hormonal contraceptives in general tend to have lighter and shorter menstrual periods after a few months, but those using non-cyclic methods often do not have any menstruation at all. Explain why this happens. ...
Traditionally, semiconductor companies controlled the entire production process, from design to manufacture. Yet many chip makers are now delegating more and more production to others in the industry. Foundry companies, whose sole business is manufacturing, have recently come to the fore, providing attr...

What is cellular organization in biology? What cell structures are in a plant cell but not in an animal cell? What is a cell nucleus? Describe its functions. What are the 4 basic structures of a cell? What is the name of the process in which cells become specialized in structu...
The rate of transcription of the trp operon in E. coli is controlled by what two regulatory processes? These two processes can regulate the trp operon up to about ___-fold due to the combined effects of these processes. By what mechanisms do these two r What...
