Examine the 5'- 3 sequence of bases of the DNA molecules (A D) shown below. I am only showing you the 5 - 3' strand of each molecule, but you can imagine the complementary 3' - 5' strand for each molecule. Which double-stranded molecule is held together by 10 hydrogen bonds? O AAAT O ATAG O TGTC O GCGA
The joining of a new nucleotide to a growing strand during DNA synthesis leads to the formation of a phosphoester bond and involves O a nucleophilic attack of the terminal P atom of the growing strand on the electrophilic 3-0 atom of the growing strand O a nucleophilic attack of the terminal 3'-0 atom of the growing strand on the electrophilic P atom of the incoming nucleotide O an electrophilic attack of the terminal 3'-O atom of the growing strand on the nucleophilic P atom of the incoming nucleotide an electrophilic attack of the terminal Patom of the growing strand on the nucleophilic 3-O atom of the growing strand
Describe the structure of DNA. The two strands of DNA are antiparallel. What does the term antiparallel mean? Describe how DNA is tightly packaged. Your description should include the terms histones, chromatin, nucleosomes and chromosomes.
A. DNA Replication Construct a DNA with 15 base pairs. (Note that the first three nucleofides of the parent DNA (3' to 5') strand correspond to a start codon and its last three nucleotides correspond to a stop codon in its MRNA counterpart later on.) Write it down as follows: a. the sequence of parent DNA (template) 3' A C A TT 5' 3' Upon undergoing DNA replication, show what one daughter DNA molecule will look like. Write it down as follows: b. the sequence of DNA Daughter 1: 3' 5' 5' 3' C. the sequence of DNA Daughter 2: 3' 3' 5' in in
just choose dont explain The alternating sugar-phosphate backbone of the DNA is hydrophobic Select one: True False
Consider normal B-form DNA. It forms a regular antiparallel double-helical structure with Watson-Crick base-pairing mediated through hydrogen bonding. The base pairs all stack upon one another, with 3.4 Å spacing between them. DNA strands having a complementary sequence will spontaneously form a double-helix in an aqueous solution. In terms of energy, what primarily drives helix formation? O Positive Entropy from base stacking van der Waals interactions O Hoogsteen interactions Positive Enthalpy from Hydrogen Bonding between GC and AT pairs Negative Enthalpy from Hydrogen Bonding between GC and AT pairs O Negative Entropy from base stacking
Given the structures of the nitrogenous bases shown in the picture, draw the structure of a part of DNA with the sequence: 5'-GTTCA-3'.
What determines the sequence of nucleotides in the template strand of DNA? (The answer can be very basic don’t need lots of details)
A strand of DNA contains the base pair 5’-T-C-A-G-C-A-T-3’. Give the base sequence onthe complementary DNA strand.
Spot the difference between the chemical structures of DNA & RNA and state the said difference in a short paragraph. Please refer in the attached picture for the answer.
Below is the 5’–3’ strand of a double-stranded DNA molecule with the following nucleotidesequences (all belong to an exon):5’ C C T A T G C A G T G G C C A T A T T C C A A A G C A T A G C 3’ 1. If the above DNA strand is the template (antisense) strand and the DNA molecule is transcribed that produced a functional mRNA. Assuming there are no mutations, the said mRNA is then brought to the site of protein synthesis,a. what would be the amino acid sequence of the synthesized polypeptide chain?b. how many possible kinds of tRNA molecule that will bring the 2nd amino acid observing wobble hypothesis? List down their anticodons.
Tabulate the differences of the various DNA conformations in terms of orientation, rise per base pair (bp), pitch per trun of helix and helix diameter.
