What has to happen before mitosis begins?
Leokris [45]

Mitosis is simply a stage in a cells life cycle, which could be broken down further into stages of mitosis. The rest (so not mitosis) is know as Interphase and is where the cell does its normal function, so if it's the cell is in a region of muscle it would contract/relax as normal etc.

Immediately before mitosis (or M phase) is what's know as G2 phase, where the G stands for growth and is where particular gene pathways are expressed to promote growth of the volume of DNA (chromosomes are duplicated, so from 46 to 92). At the end of this stage is a checking process where the DNA is scrutinised for any errors, if all is okay then the cell can proceed to mitosis, if not then the process is stopped so that errors in copying the DNA can be fixed. This is know as a restriction point and the cell must meet the requirements to pass. This is often seen as a way cells can prevent damage being replicated and therefore interfering with normal cell processes. When cells are cancerous they are able to override this and therefore divide and spread the damaged DNA.

Are all organs weighed on a triple beam balance ?
Elanso [62]

No,not all organs are weighed on a triple beam balance.

<u>Explanation:</u>

  • Usually smaller sized organs like adrenals, thyroid are commonly used to be weighed on triple beam balance, whereas larger organs like lungs, liver and heart can only be weighed on grocer's scale.
  • Only weight of the smaller body organs can be measured very precisely with the help of triple beam balance, where as if we measure the weight of the larger organs using the same triple beam balance,then the resultant value thus obtained will not be accurate enough.
  • Hence organs are weighed on a triple beam balance.
