The base-pairing rules explain how a strand of DNA acts as a template during DNA replication by ensuring that each new DNA molecule is an exact copy of the original. This is because the sequence of bases on one strand determines the sequence of bases on the other strand. The base-pairing rules ensure that the genetic information is accurately copied during cell division, which is crucial for the maintenance of genetic integrity across generations.
Explicación
## Step 1The base-pairing rules, also known as Chargaff's rules, are a fundamental principle in molecular biology. These rules state that in DNA, adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G). This is due to the specific hydrogen bonding patterns between these bases.## Step 2During DNA replication, the double helix structure of DNA unwinds, and each strand serves as a template for the formation of a new complementary strand. This process is facilitated by the base-pairing rules.## Step 3The base-pairing rules ensure that each new DNA molecule is an exact copy of the original. This is because the sequence of bases on one strand determines the sequence of bases on the other strand.## Step 4The base-pairing rules also ensure that the genetic information is accurately copied during cell division. This is crucial for the maintenance of genetic integrity across generations.
