What does replication mean in biology?
Replication in biology refers to the process by which a cell makes an identical copy of its DNA. This is essential for cell division and passing on genetic information to offspring. Replication is a highly accurate process involving multiple enzymes and proteins.
How do chromosomes turn into DNA?
Replication chemicals trigger during cell replication trigger DNA to wrap tightly around histone octamers (histone proteins) to create nucleosomes, for DNA synthesis. This happens during the prophase stage of cell replication.
What happens after the synthesis of proteins?
After proteins get modified in the Endoplasmic Reticulum, they are transported through the golgi apparatus where they get packaged into vesicles to late be secreted out of the cell or to be used within the cell.
What are steps of interphase and what happens in each?
Interphase consists of three main phases: G1, S, and G2. In the G1 phase, the cell grows, carries out normal functions, and prepares for DNA replication. The S phase is when DNA synthesis occurs, resulting in the duplication of chromosomes. Finally, in the G2 phase, the cell continues to grow and undergoes further preparations for mitosis, including the synthesis of proteins and organelles needed for cell division.
When are chromosomes duplicated?
The DNA is copied when the RNA goes in the nucleus and combines with one of the copies of the DNA and takes it to the ribosomes. When the RNA takes a copy of the DNA the DNA goes through a process called Replication.
What happens in S phase of the cycle?
Synthesis. The replication of the genetic material basically.
What key event happens during the s phase?
synthesis of DNA DNA Replication

How are proteins manufactured in a cell?
Protein synthesis happens in the cytoplasm in special organelles called ribosomes.
What happens when Golgi apparatus is removed from the cell?
There would be no vesicle shipping from the cell to where modified proteins are needed. No modified proteins. There would be no lysosome synthesis either.

What happens in the S phase of the cell cycle?
During the S phase of the cell cycle, DNA synthesis occurs, leading to the replication of the genetic material in the cell. Each chromosome is copied to produce two identical sister chromatids, which are essential for cell division. This phase is crucial for ensuring that each daughter cell receives a complete set of genetic information.
When does DNA replication occurs?
DNA replication occurs during the S phase of the cell cycle, where the cell undergoes the process of duplicating its DNA to prepare for cell division. This process ensures that each daughter cell receives an exact copy of the genetic information.
What happens s?
DNA replication happens during s-phase.
