46
During prophase at the start of mitosis, the parent cell has a diploid number of chromosomes, which consists of a complete set of chromosomes from both parents. This means that if a human cell has 46 chromosomes prior to mitosis, it would have 46 chromosomes during prophase as well.
In human cells, during prophase of mitosis, there are 46 chromosomes, which consist of 23 pairs. Each chromosome is duplicated and appears as two sister chromatids joined at the centromere. Therefore, while there are 46 individual chromosomes, they are organized as 92 chromatids.
The chromosomes coil up and condense during prophase
During mitosis, chromosomes are in their most condensed form during metaphase
prophase
In prophase, there are 46 chromosomes present, which are duplicated sister chromatids. In metaphase, there are still 46 chromosomes, but they are aligned along the metaphase plate. In telophase, the chromosomes have separated and there are once again 46 individual chromosomes in each daughter cell.

prophase
The cell's chromatin condenses into chromosomes during prophase. In contrast, telophase is where the chromosomes loosen to form chromatins.
The stage of mitosis where chromosomes shorten and thicken and the nuclear membrane begins to disappear is prophase. During prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, allowing the chromosomes to interact with the spindle fibers.
In prophase, a cell's nucleus contains the full set of chromosomes, which for humans is 46 chromosomes (23 pairs). At this stage, the chromosomes condense and become visible under a microscope as they prepare for cell division.
Question:At the beginning of prophase I there are ________ molecules of DNA in a developing human sperm cell.Your Answer:2392CORRECT ANSWER46INCORRECThalf as many (as compared to somatic cell)twice as many (as compared to mature sperm)
Yes. During prophase the chromosomes condense to prepare for cell division.
It depends on the organisms. In humans there are 46 double chromosome, which are called sister chromatids. There are a total of 92 sister chromatids, which will eventually separate into individual chromosomes during anaphase of mitosis.
