What is the role of telomeres in cell ageing?
What is the role of telomeres in cell ageing?
Loss of telomere sections leads to cell division cessation.
Differentiate between apoptosis and necrosis in terms of cell death mechanisms.
Differentiate between apoptosis and necrosis in terms of cell death mechanisms.
Apoptosis is programmed cell death involving 'suicide genes' and DNA fragmentation, while necrosis is cell injury leading to cellular content release and inflammatory response.
Explain the process of gene activation and its importance in initiating protein synthesis.
Explain the process of gene activation and its importance in initiating protein synthesis.
Activation of genes requires DNA uncoiling for transcription to occur, essential for initiating protein synthesis.
