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:

Significance Test

A statistical test to determine whether the difference between groups or the relationship between variables is due to chance or represents a true effect.

Probability

A measure of the likelihood of a given event's occurrence, expressed as a number between 0 and 1.

S Data

S Data, or self-report data, involves data collected directly from participants about themselves through questionnaires, interviews, or other introspective methods, often used in psychological assessments.

B Data

Behaviorally based data, which involve observations of an individual's behavior in natural contexts.
