Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present.
Beta cells in the pancreatic tissue release insulin when blood sugars are high, in order for insulin to be released it needs be produced and the insulin is created by a process called protein synthesis. When a beta cell produces, processes and exports insulin it uses different structures of the …show more content…
The three stages are: Interphase (which uses the most time of the cell cycle), mitosis and cytokinesis. A beta cell goes through each stage in order to repair the damaged cells and replace them with genetically identical cells in the pancreatic tissue.
Interphase, the first stage of the cell cycle, has three phases which are the following: G1, S and G2. During the G1 phase the Beta cell is very active and is growing, at this point the cell is still carrying out its normal functions. Then an exact copy of the DNA, Histones, the centrioles and the organelles are made in the S phase. Then the final part of Interphase is G2, which is where the Mitochondria and chloroplasts in the beta cell divide and the beta cell prepares for Mitosis to start. After interphase the cell begins to start mitosis, this is where the cell divides in order to produce two genetically identical cells using one parent cell. There are four stages of mitosis: prophase, metaphase, anaphase and telophase. All four stages are vital for the beta cell when going through the cell …show more content…
Whereas a differentiated beta cell isn’t able to change into a different cell, it can only make copies during cell division; this is because a differentiated beta cell has a specialised function. The beta cells specialised function is to provide insulin, whereas human stem cells are unspecialised which means the stem cell doesn’t have a specialised function but is able to differentiate into a specialised cell aswel in order to carry out functions. Both beta cells and human stem cells all contain the same genes , but the reason why a beta cell can carry out its special function is because in a specialised cell different genes a switched on and switched off, this is why a beta cell can act different to preform its specialised
