What's the length of the DNA around histone core in a nucleosome? 50 base pairs 146 base pairs 8 base pairs O None of the above

In the DNA double-helix structure, the larger of the two grooves formed by the helical twist where certain base pairs are exposed is called the:

A segment of a polypeptide chain is Arg-Gly-Ser-Phe-Val-Asp-Arg. It is encoded by the following segment of DNA: G G C T A G C T G C T T C C T T G G G G A   C C G A T C G A C G A A G G A A C C C C T Template strand with its polarity: 3’ C C G A T C G A C G A A G G A A C C C C T 5’ - Coding strand with its polarity: 3’ G G C T A G C T G C T T C C T T G G G G A  5’   Please write out the mRNA sequence generated by the template strand to produce that polypeptide chain.
