The pairing of complementary nucleotides in RNA to match with the template DNA during transcription depends on the same base-pairing rule used in DNA replication. In both processes, adenine pairs with thymine (or uracil in RNA) and guanine pairs with cytosine.
Why is complementary base pairing crucial for life?
Adenine compliments ThymineGuanine compliments Cytosine.
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.
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.
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).
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.
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.
The correct base-pairing rules for DNA are adenine (A) pairing with thymine (T), and cytosine (C) pairing with guanine (G). This complementary base pairing allows DNA replication to occur accurately, ensuring genetic information is faithfully transmitted during cell division.
In DNA, the nitrogen base adenine (A) pairs with the nitrogen base thymine (T), and the nitrogen base cytosine (C) pairs with the nitrogen base guanine (G). So the base pairs are A:T and C:G. One way to remember is that A:T spells the word "at."
