Chargaff's rule states that in a DNA molecule, the amount of adenine (A) equals the amount of thymine (T), and the amount of cytosine (C) equals the amount of guanine (G). To calculate this, you would count the number of A's and T's, and the number of C's and G's in a DNA sequence and compare them. The percentages should be approximately equal if Chargaff's rule holds true.
Yes, that is correct. Hereditary information is stored in the sequence of nitrogenous bases (adenine, thymine, guanine, and cytosine) within the structure of DNA. This sequence contains the instructions for building and maintaining an organism.
Yes this is true :) - This happens if the two strands of DNA have organic bases complimentary to one another - E.g if one strand has the Base code - TAACGATC the other strand would have the Base code - ATTGCTAG - this is because the bases pair up as so - Adenine&& Thymine and Cytosine and Guanine - this is bcause these organic bases are complimentary due to the molecular structures allowing certain number of hydrogen bonds to form between these bases - A & T have two hyrdrogen bonds and C& G have three :D xx
Yes, this is true. DNA is comprised of a backbone of deoxyribose sugars and phosphate groups. The central portion that contains the genetic code is typically made up of four monomers: adenine, guanine, cytosine, and thymine.
The point of DNA is that it is a very long, continuous chain of nitrogenous bases (cytosine, guanine, adenine and thiamine linked by a C5 sugar (deoxyribose) and phosphate groups. There are 2 complementary chains that come together to create DNA (for every T base, there'll be a T complementary and vice versa and the same is true for C and G).
Adenine (A) and Thymine (T) form a true complementary pair, as well as Guanine (G) and Cytosine (C). This is due to the specific hydrogen bonding patterns that occur between these bases in DNA.
cytosine and guanine
In DNA, adenine pairs with thymine and cytosine pairs with guanine through hydrogen bonding. This complementary base pairing allows for accurate DNA replication during cell division.
it is true to some extent. The DNA bases are Adenine(A), Thymine(T), Cytosine(C) and Guanine(G). Now the reason i say it is true is because A forms a double hydrogen bond with T only and C forms a triple hydrogen bond with G only.
There are four nitrogen bases found in DNA: adenine, guanine, cytosine, and thymine.
False. Adenine pairs with thymine and guanine pairs with cytosine.
Both DNA and RNA have nitrogen bases, but RNA contains uracil instead of thymine found in DNA. The nitrogen bases in DNA are adenine, cytosine, guanine, and thymine, while in RNA they are adenine, cytosine, guanine, and uracil. These bases pair according to specific base pairing rules (A with T/U and C with G) during replication and transcription processes.
yes
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
The 1953 Nature paper by James Watson and Francis Crick stated that each base pair (purine-pyrimidine pair, A-T and C-G) was held together by two hydrogen bonds.It is now established that, while this is true for adenine-thymine (A-T), the cytosine-guanine (C-G) pairing involves three hydrogen bonds.For a reproduction of the original paper, see:http://www.nature.com/nature/dna50/archive.html
Purines form hydrogen bonds to pyrimidines. Adenine pairs up with Thymine (in DNA) and Uracil (in RNA) and Guanine pairs with Cytosine. A-T pairing has 2 hydrogen bonds and C-G pairing has 3 hydrogen bonds.
A linear pair are always supplementary, 180 degrees not 90.
