We should take a step back and consider the function of the cell’s nucleus before delving deeper into the topic of DNA replication. The nucleus, which is a cellular organelle, is where the genetic information of the cell is stored. The nucleus is a structure that is found in the center of the cell. The nucleus of the cell is in charge of directing the cellular activity of the organism. This function includes the creation of new molecules such as proteins and nucleic acids, among other things. The deoxyribonucleic acid (DNA) found within the nucleus is responsible for regulating protein synthesis. A small amount of DNA can be found within the mitochondria as well. This is an appropriate time to point out that all cells will have a nucleus at some point during their lifetime, but not for the duration of their lives. Do red blood cells have a nucleus, or do they not? No. Red blood cells (RBCs) are also referred to as erythrocytes in some circles. Due to the fact that RBCs do not replicate during their lifetime, there is no requirement for a nucleus, and the cell is recycled when it reaches the end of its lifespan, which is approximately 120 days (Seeley et al., 2014).
Critical Thinking: We must take into consideration the length of time it takes for the cell cycle to complete. How long does it take to complete this task? There is an interphase and a mitotic phase in the cell cycle. The interphase of the cell cycle takes up the majority of the time, whereas the mitotic phase, also known as the M-phase, is the final stage of the process. The M-phase, which occurs at the end of the cell’s division process to produce two daughter cells, may be the most critical step. Here is a video on DNA replication that I used to watch when I was in school. I hope it is of Helpance to you. There is a demonstration of how both strands of the DNA helix are unzipped and copied to produce two identical DNA molecules in this video.
I went to this website and discovered a plethora of additional DNA videos! Here’s a question for you: What exactly are these Okazaki fragments?
