What else can I help you with?
Is it true or false that adenine always pairs with guanine?
False. In DNA and RNA, adenine (A) pairs with thymine (T) in DNA and with uracil (U) in RNA, while guanine (G) pairs with cytosine (C). Adenine and guanine are both purines, but they do not pair with each other during nucleic acid formation.
How do you calculate the chargaff's rule?
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.
According to the Principle of base pairing hydrogen bonds could form only between adenine and cytosine true or false.?
False. According to the Principle of base pairing, hydrogen bonds specifically form between adenine and thymine (or uracil in RNA) with two hydrogen bonds, and between cytosine and guanine with three hydrogen bonds. Adenine and cytosine do not form base pairs with each other.
Is it true that Hereditary information is stored in the sequence of nitrogenous bases within the structure of DNA?
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.
Can a single DNA strand bond with another single DNA strand?
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
Which of these bases form a true complementary pair?
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.
What bases forms a true complementary pair?
cytosine and guanine
Which is true of the base pairing seen between two DNA strands?
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.
True or False In DNA a base can pair with another base?
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.
Adenine guanine cystocine and thymine are the four nitrogen bases in DNA true or false?
There are four nitrogen bases found in DNA: adenine, guanine, cytosine, and thymine.
True or false The strands of a DNA molecule are held together by hydrogen bonding between adenine with guanine molecules and cytosine with thymine molecules?
False. Adenine pairs with thymine and guanine pairs with cytosine.
What is true about the nitrogen bases in DNA and RNA?
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.
Can both angles in a pair of complementary angles can be obtuse true or false?
yes
Which bases does Guanine always bond with to form a pair in DNA?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
What is the error in Watson-Crick DNA model paper?
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
How do the nucleotides match up in the DNA?
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.
Is it true or false that adenine always pairs with guanine?
False. In DNA and RNA, adenine (A) pairs with thymine (T) in DNA and with uracil (U) in RNA, while guanine (G) pairs with cytosine (C). Adenine and guanine are both purines, but they do not pair with each other during nucleic acid formation.
