Because if the pairing of the bases is incorrect then a mutation will form that can be silent or deadly .
G (Guanine) pairs with C (Cytosine) A (Adenine) pairs with T (Thymine)
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.
The structure of DNA relies on a base-pairing rule. This means that in DNA, Adenine binds to Thymine and Guanine binds to Cytosine. The complementary base is the base that binds to the base in question. Therefore A is complementary to T, C is complementary to G, etc. So if you had a strand of DNA, for example; ATT-CCA-GTC The complementary strand (which would bind to the above) would be; TAA-GGT-CAG
Antiparallel base pairing refers to the arrangement of nucleotide bases in DNA strands that run in opposite directions. In this arrangement, the 5' end of one strand is paired with the 3' end of the complementary strand. This allows for the formation of stable hydrogen bonds between the bases to maintain the structure of the DNA double helix.
The correct pairing of the 4 amino acids is based on complementary base pairing in nucleic acids: adenine pairs with thymine, and cytosine pairs with guanine.
Base pair complementarity ensures faithful DNA replication. Remember that a base can only pair with a definite pair and not with just about any base therefore this ensures high fidelity of replication. If guanine can only pair with cytosine the same way that adenine can .only pair with thymine then the copying of the DNA will be accurate.
Why is complementary base pairing crucial for life?
Base pairing in DNA involves the specific hydrogen bonding between nucleotide bases, where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). This complementary base pairing is crucial for maintaining the double-helix structure of DNA and ensures accurate replication during cell division. The pairing also plays a key role in the encoding of genetic information, as the sequence of these bases determines the genetic code.
The complementary base pairs in a DNA molecule are stabilized by hydrogen bonds between adenine and thymine, and between cytosine and guanine. These hydrogen bonds help hold the two strands of DNA together in the double helix structure.
Guanine is a complementary base for cytosine in DNA.
Complementary base pairs are specific pairs of nucleotide bases in DNA that always bond together: adenine with thymine, and cytosine with guanine. These pairs contribute to the structure of DNA by forming the double helix shape, where the bases are held together by hydrogen bonds. This pairing ensures that the two strands of DNA are complementary and allows for accurate replication and transmission of genetic information.
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.
