Question: What is the significance of adenine, thymine, guanine, and cytosine in the structure of a DNA molecule? What is the significance of adenine, thymine, guanine, and cytosine in the structure of a DNA molecule?
Answer: The sequence of these bases is read in groups of three at a time. Since there are four bases, and they are read in groups of three, there are 64 possible combinations in each group of three (since 4 cubed is 64).
Now, there are 20 amino acids in total, amino acids being the building blocks of protein.
So, from these 64 combinations, there are specific combinations that are used to refer to each of the 20 amino acids specificially.
(It is true that more than one base grouping may refer to any particular amino acid since there is a 64:20 ratio, but one base grouping can never refer to more than one amino acid.) Thus, each base grouping will identify a specific amino acid only. And the base groupings are read and translated into the appropriate amino acid.
Now the amino acids are strung together in the same order that the base groupings occur in in the DNA strand. This causes a specific protein to be built, and you are built out of protein.
By the way these base groupings of threes of the A, T, G, and C bases are called codons.
Question: What contains Three Phosphoric Acid Molecules, One Ribose Molecule, and 1 Adenine Molecule? Also what contains Two Phosphoric Acid Molecules, One Ribose Molecule, and 1 Adenine Molecule.
I'm trying to study for my quiz and I've been doing this ever since I got home?
Answer: ATP - Adenosine Triphosphate
Adenosine is Adenine and ribose bonded together.
Question: If a segment of one strand of a DNA molecule has 500 adenine bases, how many thymine bases does the other ? If a segment of one strand of a DNA molecule has 500 adenine bases, how many thymine bases does the other strand have?
Answer: In DNA, adenine binds to thymine. So, if you have 500 adenine bases, you have 500 thymine bases as well.
Question: What are the sizes of guanine, cyctosine, adenine and thymine in nm? I mean their sizes in terms of width and length. Please help, i have browsed the web but could not find any useful informarion.

Question: What is the number of hydrogen bonds between Adenine & Thymine and Guanine & Cytosine? I have to do a 3D dna model and one of the requirements was to show the hydrogen bonds between the nitrogen bases and I just wondering how many there are between A & T and G & C. Thanks for the help!
Answer: A and T have double H bonds...
C and G have triple H bonds...
see this links below:
Question: If adenine bonds with guanine and thymine bonds with cytosine, the DNA molecule would? 1. bulge where cytosine bonds with thymine.
2. be constricted along its entire length.
3. constrict where adenine bonds with guanine.
4. partially constrict and partially bulge along its length.
5. be highly reactive.
Answer: It's 4...it will bulge where the purines are linked together because they are long (2 rings) and it will constrict where the pyrimidines are linked together because they are shorter (1 ring).
Question: Energy released from breaking of 2nd and 3rd phosphate groups attached to adenine is so strong, WHY? I understand that when the bond between the 2nd and 3rd phosphate group is broken down it releases the highest energy (about 31 kj per mole). But why is the breaking of these two groups so strong compared to others? No form of research I have come upon has clarified or provided detail as to why it occurs.
Answer: It holds onto them more tightly.
More energy stored in the bond = more energy when released.
A bit more detail, it depends on the structure, it's easier to give up one group than each successive group. Has to do with the charge on the atoms.
Question: How would the shape of a DNA molecule change if adenine paired with guanine and cytosine paired with thymine?
a. The DNA molecule would be shorter.
b. The DNA molecule would be circular.
c. The DNA molecule would be longer.
d. The DNA molecule would have irregular widths along its length.
e. The DNA molecule would have regions where no base-pairing would occur.
And where can I find more information explaining this? A link or something that could help me better grasp this?
Answer: Nothing would happen, only A-T and C-G can attach. Think of it as a puzzle, the pieces of A-G can not fit together. I don't know how else to explain it, so your answer would be E.
Question: What's the difference between ATP and an activated nucleotide which has Adenine as it's base? anyone?
Answer: ATP has a ribose, and an activated nucleotide has a deoxyribose.
Question: If a species has 35% adenine in its DNA, how do you determine the percent of the other three bases? What is the advantage of the double stranded aspect of the DNA?
Answer: adenine bonds with thymine in DNA (not RNA)...so there's 35 % thymine. That gives 70% of the DNA determined. The remaining 30 percent must belong to guanine and cytosine...each of which must be 15%
Question: family of nitrogenous bases containing adenine and guanine? family of nitrogenous bases containing adenine and guanine?
macromolecules that account for 50% of dry weight in most cells?
thanks its for a wordsearch !
Answer: Try searching for the properties of purines.
I think the macromolecules would be proteins and nucleic acids.
Question: How would the shape of dna molecule change if adenine paired with guanine and cytosine paired with thymine?
Answer: The Shape of a DNA strand is always the same - double-helix and turns at every 10 base pairs. Then, the strand itself will associate with Histones(proteins) and coil around it to form nucleosomes. Then 8 nucleosomes will form a soleniod and then the soleniod will coil around itself to form the chromatin fibre. When the chromatin fibre condenses, they are chromosomes.
Question: Did watson and crick's model account for the equal amounts of thymine and adenine in DNA? It's for a biology assignment that I do not understand. Are there any sites anyone has for help on these kind of questions anyone could tell me they can add also?
Answer: probably..since they pair together...you would think that there is the same number of them
Question: Why does DNA replication usually occur at Adenine or Thymine? Is there a energy requirement or such?
Answer: huh? what do you mean?
DNA replication occurs at the 3' end of the strand, each nucleotide A, C, G, T, being added according to the complementary strand.
Looked up origins of replication. not even there do we have a consensus sequence in eukaryotes, in some yeast they are indeed AT-rich sequences which may be more accessible due to the weaker hydrogen bonding, but in other eukaryotes there is no such indication.
