Answer:

c. Methylated CpG islands is associated with long term gene repression.

Explanation:

The CpG sites or islands is a biological term that describes the genomic regions in which CpG sites occur; a region of DNA, in which cytosine nucleotide is followed by a guanine nucleotide in the linear sequence of bases along its 5' → 3' direction.

The CpG islands is characterized with a high frequency of CpG sites, with at least 200 bp, a GC percentage greater than 50%, and an observed-to-expected CpG ratio greater than 60%.

The existence of CpG islands is also associated with low levels of methylation in that genomic area, which has to do with the regulation or repression of gene expression

Like all forms of life on Earth, all microbial cells perform three major types of activities: __________.
pashok25 [27]

Answer:

4. metabolism, growth, and evolution

Explanation:

Living organisms show different characteristics like respiration, movement, metabolism, growth, evolution, respiration, excretion, nutrition. Most of the microbes are microscopic and unicellular which means they are made up of only one cell but they are also living.

They perform three major types of activities like metabolism, growth, and evolution. This can be seen by culturing bacteria on suitable media. So in the medium, it can be observed that they consume the food present in media and extract energy from it through metabolic activities and are showing growth. All micro-organisms evolve due to mutation. So the correct answer is 4.
