DNA is exchanged between homologous chromosomes in a process called "crossing over" or "genetic recombination," which is important for maintaining diversity in the genetic pool from one generation of individuals to the next.
Yes all living things, (starting from a cell) have chromosomes. chromosomes are found in DNA and if cells didn't have DNA they wouldn't exist.
double chromosomes first become visible in which step of mitosis?
There is no such number, depending on the organism the number of chromosomes varies from 1 to about 30,000,000!
Chromosomes are the vital message passing things during birth. This is a sentence containing the word chromosomes.
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
The number of chromosomes in daughter cells formed by the first division is the same as the parent cell, typically 46 chromosomes in humans. This is because during the first division, chromosomes are replicated and then distributed equally between the daughter cells.
Sex chromosomes were first discovered in insects, specifically in fruit flies by Nettie Stevens and Edmund Wilson in 1905. They observed that the differences in male and female sex characteristics were due to the presence of these specialized chromosomes.

Chromosomes are the message transferring things in humans. They are part of our biological body.
during prophase
Chromosomes first appear to be double during the S phase of the cell cycle when DNA replication occurs. This results in two identical sister chromatids joined by a centromere in preparation for cell division.
