Given That X Is a Binomial Random Variable, the Binomial $$\geq$$

question 27

Short Answer

Given that X is a binomial random variable, the binomial probability P(X $$\geq$$ x) is approximated by the area under a normal curve to the right of: $$\begin{array} { | l | l | } \hline \text { A. } & x - 0.5 \\\hline \text { B. } & x + 0.5 . \\\hline \text { C. } & x - 1 . \\\hline \text { D. } & x + 1 . \\\hline\end{array}$$

The inactive X chromosome is one of the two X chromosomes in female mammals that is condensed and transcriptionally inactive, a process known as X-chromosome inactivation.

Histones

Proteins that package and order the DNA into structural units called nucleosomes.

Transcriptionally Active

Refers to genes that are currently being expressed, with their DNA being transcribed into messenger RNA.

Euchromatin

A loosely coiled chromatin that is generally capable of transcription. Compare with heterochromatin.
