How are base pairing rules and complementary base pairs related?
Base pairing rules dictate that in DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G). These pairs are called complementary base pairs because they always bond together due to their specific chemical structures and hydrogen bonding capabilities. Together, these rules ensure the accurate replication and transcription of DNA.
What is nucleotide pairing?
Nucleotide pairing refers to the specific base pairing interactions between the nucleotides of DNA or RNA molecules. In DNA, adenine pairs with thymine, and cytosine pairs with guanine through hydrogen bonding. In RNA, uracil replaces thymine in pairing with adenine. These base pair interactions are essential for maintaining the structural integrity and information coding in nucleic acid molecules.
How is complementary base pairing different when pairing DNA to DNA than pairing DNA to mrna?
Complementary base pairing in DNA-DNA pairing involves adenine (A) pairing with thymine (T) and cytosine (C) with guanine (G), following the rules of Watson-Crick base pairing. In DNA-mRNA pairing, uracil (U) replaces thymine, so adenine (A) pairs with uracil (U) in mRNA instead of thymine (T).
In a DNA molecule what base pair could normally be composed of?
A DNA molecule can have base pairs composed of adenine (A) pairing with thymine (T), and guanine (G) pairing with cytosine (C). This is known as complementary base pairing in DNA.
How the tRNA docks on the mRNAexplain in terms of nitrogen bases?
The tRNA docks onto the mRNA through complementary base pairing between the anticodon on the tRNA molecule and the codon on the mRNA strand. This base pairing ensures that the correct amino acid is brought to the ribosome during protein synthesis. The interaction between the nitrogen bases is specific, with adenine (A) pairing with uracil (U) and cytosine (C) pairing with guanine (G).
What is meant by the term complementary base pairing in genetics?
Complementary base pairing in genetics refers to the specific pairing of nucleotide bases in DNA molecules. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is essential for DNA replication and the transmission of genetic information.
DNA exhibits base pairing?
DNA base pairing refers to the specific hydrogen bonding between adenine and thymine, as well as cytosine and guanine. This complementary base pairing allows for DNA replication and helps maintain the double-stranded structure of DNA. The base pairing ensures the accurate transmission of genetic information during cell division.

What are the correct base-pairing rules of DNA?
The correct base-pairing rules in DNA are adenine (A) pairing with thymine (T) and guanine (G) pairing with cytosine (C). This forms complementary base pairs that contribute to the double-helix structure of DNA.
What are the wobble rules for codon-anticodon pairing?
The wobble rules refer to the flexibility in base pairing between the third base of a codon and the first base of an anticodon during protein synthesis. This flexibility allows for non-standard base pairing, such as G-U pairing, which helps in reducing errors during translation.
What is complementary base pairing and how does it contribute to the stability of DNA molecules?
Complementary base pairing is the specific bonding between adenine and thymine, and between cytosine and guanine in DNA molecules. This pairing ensures that the two strands of DNA are held together in a stable double helix structure. The hydrogen bonds formed between the complementary base pairs contribute to the overall stability of the DNA molecule.
How is complementary base pairing different when pairing DNA to DNA than pairing DNA to mrna?
Complementary base pairing in DNA-DNA pairing involves adenine (A) pairing with thymine (T) and cytosine (C) with guanine (G), following the rules of Watson-Crick base pairing. In DNA-mRNA pairing, uracil (U) replaces thymine, so adenine (A) pairs with uracil (U) in mRNA instead of thymine (T).
Which of the following is true regarding complementary base pairing in DNA and RNA molecules?
Although the base pairing between two strands of DNA in a DNA molecule can be thousands to millions of base pairs long, base pairing in an RNA molecule is limited to short stretches of nucleotides in the same molecule or between two RNA molecules.
Do complementary base pairing match up with complementary sugars?
No, complementary base pairing refers to the specific hydrogen bonding between bases in DNA (A pairs with T, G pairs with C). Complementary sugars do not refer to a specific pairing in the same way; sugars in DNA (deoxyribose) are the same for all nucleotides (A, T, C, G), while RNA (ribose) has a slightly different sugar structure.
In a DNA molecule what base pair could normally be composed of?
A DNA molecule can have base pairs composed of adenine (A) pairing with thymine (T), and guanine (G) pairing with cytosine (C). This is known as complementary base pairing in DNA.
