Replication
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
If an Allium cell has 30 chromosomes before Mitosis, then each daughter cell will also have 30 chromosomes after Mitosis. This is because during Mitosis, the chromosomes replicate and are equally distributed between the two daughter cells.
No, transcription is the process of creating an mRNA copy of the DNA in order to create a function process (by translation at the ribosomes). However, DNA does replicate before mitosis occurs - this is so that each daughter cell at the end of mitosis ends up with the same number of chromosomes as the original cell.
it divides in two parts.
They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)
DNA replicates during the S phase of the cell cycle, which occurs before mitosis.

Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
Chromosomes contain tightly-packed DNA, and are visible only when the cell is preparing to replicate (before mitosis/meiosis).
DNA replicates during the S phase of interphase, which occurs before mitosis. In the S phase, each chromosome is replicated to form two identical sister chromatids connected at the centromere.
no DNA replicates before mitosis. It replicates in the S phase of inter phase
Centrosomes replicate during the S phase of the CELL CYCLE not mitosis. Mitosis is one stage of the cell cycle. Replication does not happen during mitosis(M phase). It happens during the S phase. In fact, the opposite happens chromosomes are consdensed and packaged in preparation for splitting.
If an Allium cell has 30 chromosomes before Mitosis, then each daughter cell will also have 30 chromosomes after Mitosis. This is because during Mitosis, the chromosomes replicate and are equally distributed between the two daughter cells.
The DNA replicates during the S phase of the cell cycle, which occurs before mitosis starts. DNA replication ensures that each daughter cell receives a complete set of genetic information during cell division.
No, transcription is the process of creating an mRNA copy of the DNA in order to create a function process (by translation at the ribosomes). However, DNA does replicate before mitosis occurs - this is so that each daughter cell at the end of mitosis ends up with the same number of chromosomes as the original cell.
DNA replication before mitosis ensures that each daughter cell receives a complete set of genetic information. This is critical for maintaining genetic stability and ensuring that each new cell has the necessary genetic instructions to function properly.
Strictly speaking, the chromosomes are not copied during mitosis but already before cell division takes place. This phase is called INTERPHASE and is again divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). The replication of chromosomes only happens in the S phase.
