Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.
Answer:
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.

Brainliest please?
Answer:
The mRNA or the messenger RNA plays an important role in the cells. It is responsible for the transmission of genetic information from the DNA and this is sent to the ribosome and in the ribosome, the amino acid sequence is being specified, thus producing gene expression.
Explanation:
hope this help pls give me brainly
I was gonna say thank you for the free points but lol.
anw the correct answer is Neighborhood environment
Answer:
C) Protein synthesis is the process through which cells read DNA and build the molecular components of new cells.
Explanation:
DNA is the genetic material of the organisms. It stores the genetic information used to make the molecules and other components required for the new cells. This process of formation of molecules is called protein synthesis. During protein synthesis, The DNA forms a complementary messenger RNA (mRNA) in the nucleus of a cell. Synthesis of mRNA from DNA is called transcription. The mRNA released into the cytoplasm where codons on mRNA sequence translate into a polypeptide or protein molecules by linking a chain of amino acids by peptide bonds.
