DNA undergoes replication during the S phase of interphase in the cell cycle.
I'm not sure what you mean by "samotic cell." If you meant "somatic cell," then yes, somatic cells undergo mitosis for growth and repair. However, they do not undergo meiosis, which is reserved for the production of gametes (sperm and egg cells).
No, chromosomes do not undergo crossover during mitosis. Crossover, also known as genetic recombination, occurs during meiosis, not mitosis.
No, brain cells do not undergo meiosis. Meiosis is a process of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. Brain cells, known as neurons, undergo a different process called mitosis for growth, repair, and maintenance of the brain.
No, sponges do not undergo meiosis as they reproduce through a process called fragmentation or budding where new individuals develop from a parent sponge. Meiosis is typically found in organisms that reproduce sexually to produce gametes.
Your "germ" (or sex, but I prefer germ) cells undergo mitosis to create more diploids, but then they undergo Meiosis I to form a haploid. In boys, the germ cells will undergo Meiosis II to form their complete germ cells. In girls, the cell will only complete Meiosis II if the egg is fertilized. So the answer is sort of yes... the diploids will undergo Mitosis, but to actually get germ cells... they must undergo Meiosis.
Body cells do not undergo meiosis. Reproductive cells undergo meiosis, body cells, mitosis.
NoBacteria cannot under go meiosis or mitosis. Protists can undergo them

Replication of DNA
Before a cell can undergo Mitosis (in which prophase is the first stage) It must first undergo synthesize certain proteins, produce organelles for the daughter cells, and arrange the structures for cell division. It also needs to undergo DNA replication.
No, chromosomes do not undergo crossover during mitosis. Crossover, also known as genetic recombination, occurs during meiosis, not mitosis.
No, brain cells do not undergo meiosis. Meiosis is a process of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell.

A duplication of the chromosomes is what must happen before meiosis can begin.
Gametes don't undergo Meiosis, but are CREATED in Meiosis.Gametes should be haploid. Otherwise chromosomal number will be doubled in offspring
Your "germ" (or sex, but I prefer germ) cells undergo mitosis to create more diploids, but then they undergo Meiosis I to form a haploid. In boys, the germ cells will undergo Meiosis II to form their complete germ cells. In girls, the cell will only complete Meiosis II if the egg is fertilized. So the answer is sort of yes... the diploids will undergo Mitosis, but to actually get germ cells... they must undergo Meiosis.
During meiosis, genetic material undergoes crossing over when homologous chromosomes exchange segments of DNA. This process increases genetic diversity by creating new combinations of genes. In mitosis, crossing over does not occur as it involves the replication and division of identical chromosomes.
