In Contrast to Vertebrates, There Is Very Little DNA Methylation

question 44

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.

Definitions:

Fixed Costs

Regularly occurring costs that remain constant in total, irrespective of changes in operational levels or volume of output.

Variable Costs

Costs that change in direct proportion with the level of output or activity of a business.

Underapplied Overhead

occurs when the allocated manufacturing overhead cost is less than the actual overhead incurred, leading to a discrepancy.

Overapplied Overhead

A situation where the allocated manufacturing overhead costs exceed the actual overhead costs incurred.
