In Contrast to Vertebrates, There Is Very Little DNA Methylation

Short Answer

In contrast to vertebrates, there is very little DNA methylation in the genomes of invertebrates such as Drosophila melanogaster and Caenorhabditis elegans. Indicate whether you expect each of the following statements to be true (T) or false (F) regarding 5?-CG-3? dinucleotide sequences in the genome. Your answer would be a four-letter string composed of letters T and F only, e.g. TTTT.
( ) On average, approximately one dinucleotide out of every 16 in the human genome is a CG dinucleotide.
( ) On average, approximately one dinucleotide out of every 256 in the D. melanogaster genome is a CG dinucleotide.
( ) The proportion of CG dinucleotides in the human genome is more than that of C. elegans.
( ) The proportion of CG dinucleotides in the human genome is more than that expected by chance.
