Students have asked these similar questions
How many bits of information are stored in an 8-mer DNA sequence? In the E. coli genome? In the human genome?
In general, which part of a DNA sequence will have the best quality? (Ex. Beginning, middle, end?) Why?
I have built an urn model for a DNA sequence. I have taken the letters from a sequence 1946 nucleotides long. The urn contains 259 Adenines, 699 Cytosines, 401 Thymines and 587 Guanines
How many start codons will I find on average in the entire sequence when I draw all of the bases from the urn without replacement?
Please I'm not too sure how to tackle this.

With this technique, DNA molecules are placed in a gel, an electrical current is applied to the gel, and the DNA molecules migrate toward the positive (+) pole of the current. What aspect of its structure causes a DNA molecule to migrate toward the positive pole?arrow_forward

- We have talked about several examples of cis-acting elements that have dyad symmetry (inverted repeat symmetry). Some function on the level of DNA, and others function on the level of RNA. Give one example of one that functions at the DNA level and briefly explain why the sequence requires dyad symmetry to work properly. Note: you don't have to give an exact sequence, just the name of the element. Edit View Incort Format Tools Tabloarrow_forwardWhat are cis acting DNA sequences?
