Answer:
Hypermethylation of___ promoters will lead to reduced expression of the correspondent genes. Some genes such as Cell Cycle stop genes _and__DNA repair genes_need to be expressed. When they__are not expressed_, this can lead to cancer.
Explanation:
Oncogenes are genes that may trigger cancer, where they are generally overexpressed (i.e., expressed at high levels). Although there are well-documented exceptions to this rule, DNA methylation generally represses gene expression by preventing the binding of transcription factors to promoters. It is known that the hypermethylation of tumor suppressor genes including, for example, cell cycle stop genes and DNA repair genes, may lead to cancer. Similarly, hypomethylation of oncogenes such as, for example, Cyclin D1 (a cyclin-dependent kinase involved in cell cycle progression), may also contribute to carcinogenesis.

Answer:
The correct answer is - true.
Explanation:
Popular genetics is the study of genetic diversity which is having several hypotheses and theories about genetic diversity and mutation of a particular genome.
The selection of such mutations in a genome occurs due to diversification. This postulates that due to the different environmental conditions two subpopulations of a species can have different alleles o a specific locus of the genome.
