A one base-pair change in a genetic sequence is called a mutation. revertible frameshift insertion complementation

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.

A DNA sequence consists of a string of elements called nucleotides, in a defined order. Suppose the DNA sequence of a virus is 20 nucleotides long. If each nucleotide can be either a G, T, C, or A, how many different sequences are possible?

Alternative exon splicing contributes to resolving the G-value paradox. Group of answer choices True False

The phenomenon where double-helical DNA absorbs UV light less than does single-stranded DNA is referred to as intercalation hyperchromism hypochromism base-stacking None of the these are correct.

The X's correspond to the missing information. You need to determine what those X's represent DNA STRAND: XXX-CCC-GGG-GCG-XXX-XXX-XXX-GCC-ATA-TTA-XXX RNA STRAND: XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX PROTEIN: Met - X - X-X - Thr - Val - Glu-X-X-X - Trp To be clear, your answer is just the 3 sequences above without the X's (the highlighted yellow parts). There may be more than 1 correct answer for some parts of this assignment. Any answer your choose is fine. If you are unclear on how there could be more than 1 correct answer, review the lecture related to protein translation. Provide me with the: 1. Complete DNA sequence of 33 nucleotides 2. Complete RNA sequence of 33 nucleotides 3. 11 amino acids

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:
