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.

What is a single celled organism that have no nucleus and can either benefit or harm the body
lidiya [134]

Answer:

Bacteria

Explanation:

Bacteria have no true nucleus because it's a prokaryote. It couldn't have been a virus because all naturally occurring viruses are pathogenic unless treated by radiation.

We have two types of bacteria,

  1. Pathogenic
  2. Commensals

Pathogenic bacteria will definitely cause disease. Commensals, however, have don't harm us and have the ability to help us.

Eg: Flora (bacteria) in our intestines produce vitamin K and most of the vitamin B complex. They also compete with the pathogenic bacteria that you might've ingested and don't allow them to increase to the number that can cause disease.

Which of the following sets of materials is required by both eukaryotes and prokaryotes for replication? Group of answer choices
erastova [34]

Answer:

Double-stranded DNA.

Explanation:

Replication may be defined as the process of formation of the daughter DNA from the parent DNA with the help of enzymes and proteins. The three main process of replication are inititation , elongation and termination.

The double stranded DNA molecule undergoes the process of replication. Four different dNTPs - adenine, guanine, thymine and cytosine are required for the process of replication.  Primers are required for initiation of the process of replication and ori region is the inititaion point of replication.

Thus, the correct answer is option (a).
