The four bases must match otherwise the protein that is formed will be incorrect and can cause a fatal mutation. Proteins then have to be folded into the proper three dimensional conformation to work properly.
A number of diseases, including Alzheimer's disease, may be considered to be protein-folding diseases.
The base pairing rules in DNA (A pairs with T, and C pairs with G) ensure that during replication, each strand serves as a template for the creation of a new complementary strand. This allows for accurate and efficient replication of the genetic information.
This is false transcription does not follows the same base-pairing rules as DNA replication except for cytosine which has a different partner. Transcription begins with an enzyme called RNA polymerase.
DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.
adenine
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.
Adenine pairs with thymine, and guanine pairs with cytosine. This complementary base pairing forms the double helix structure of DNA, where hydrogen bonds hold the pairs together. This pattern allows for DNA replication and transmission of genetic information.
DNA replication
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.
During DNA replication, thymine is replaced by the base uracil.
The base-pairing rules in DNA are that adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). This complementary base pairing allows for the accurate replication of DNA during cell division.
Well the base paring rules are the rules that state that cytosine pairs with guanine and adenine those pair with thymine in DNA, and also that adenine pairs with uracil in RNA. On the other hand, the DNA structure is the crosspieces and combinations of four chemicals called nucleotides: adenine, cytosine, thymine, and guanine. Adenine only links with thymine and cytosine only links with guanine. The structure is called a double helix, and is common to all DNA.
DNA polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand during replication, using the base-pairing rules (A pairs with T, and G pairs with C).
