Final answer:
The statement that 5-Methylcytosine cannot be transmitted through cell division is false, as this and other epigenetic changes can be heritable and impact gene expression without altering DNA sequence.
Step-by-step explanation:
The statement that 5-Methylcytosine (5-mC) is considered to be an unstable epigenetic mark that cannot be faithfully transmitted through cell division is false. Epigenetic changes, including DNA methylation like 5-mC, can indeed be maintained through multiple rounds of cell division and are thus heritable to a certain degree. These heritable epigenetic modifications do not alter the DNA sequence itself but can impact gene expression and chromatin structure, influencing the cellular phenotype
. In the context of cancer, there is significant interest in understanding how epigenetic changes, such as DNA methylation and histone modifications, contribute to abnormal cell proliferation and tumor development. In this vein, epigenetic regulation is crucial for normal development as well as disease states.
