If you are asking why G must pair with C and A must pair with T it is because of the their size differences. Two of them are pyrines and two are pyramidines, this means that 2 are larger and 2 are smaller. In order for the double helix to be consistent they must pair with each other in order to create the helix.
What else can I help you with?
How are the two chains of a double helix held together?
The two chains of a DNA double helix are held together by hydrogen bonds between complementary base pairs. Adenine pairs with thymine, and cytosine pairs with guanine. These hydrogen bonds form the base pairs that hold the two strands of DNA together.
How do the bases in DNA pair up to form the double helix structure?
The bases in DNA pair up in a specific way to form the double helix structure. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is called complementary base pairing, and it helps stabilize the double helix structure of DNA.
Adenine is to thymine as guanine is to?
Cytosine. In DNA base pairing, adenine pairs with thymine, while guanine pairs with cytosine. This forms the complementary base pairs that make up the double helix structure of DNA.
Single helix is more stable as compared to the double helix?
The double helix of DNA is more stable than a single helix due to the hydrogen bonding between complementary base pairs and the structural support provided by the sugar-phosphate backbone. The double helix structure allows for efficient storage and replication of genetic information.
What is the name of the twisted ladder shape of a DNA molecule?
The twisted ladder shape of a DNA molecule is called a double helix. The double helix structure consists of two strands that are twisted around each other, forming a shape resembling a twisted ladder or spiral staircase. This iconic structure was first described by James Watson and Francis Crick in 1953, revolutionizing our understanding of genetics.
Adenine pairs with what in the double helix?
In the double helix structure of DNA, adenine pairs with thymine through hydrogen bonding, forming a complementary base pair.
How the use of bonds holds the double helix together?
Generally hydrogen bonds between the different base pairs holds the double helix together.
How are the two chains of a double helix held together?
The two chains of a DNA double helix are held together by hydrogen bonds between complementary base pairs. Adenine pairs with thymine, and cytosine pairs with guanine. These hydrogen bonds form the base pairs that hold the two strands of DNA together.
How do the bases in DNA pair up to form the double helix structure?
The bases in DNA pair up in a specific way to form the double helix structure. Adenine pairs with thymine, and guanine pairs with cytosine. This pairing is called complementary base pairing, and it helps stabilize the double helix structure of DNA.
How are the two strands of the double helix held together?
The two strands of DNA double helix are held together by hydrogen bonds between complementary bases on opposing strands. Adenine pairs with thymine, and guanine pairs with cytosine. These base pairs create the rungs of the DNA ladder, stabilizing the overall structure of the double helix.
What bond DNA forms a double helix?
DNA forms a double helix structure due to hydrogen bonds between complementary base pairs. Adenine pairs with thymine, while guanine pairs with cytosine, creating the stable double-stranded DNA molecule.
What is the shape of DNA molecule and how do base pairs fit into the shape?
The DNA molecule has a double helix shape, resembling a twisted ladder. The two strands of the helix are composed of a sugar-phosphate backbone, while the rungs of the ladder consist of complementary base pairs: adenine pairs with thymine, and cytosine pairs with guanine. These base pairs fit snugly in the center of the helix, held together by hydrogen bonds, which stabilize the structure and allow for the encoding of genetic information.
Adenine is to thymine as guanine is to?
Cytosine. In DNA base pairing, adenine pairs with thymine, while guanine pairs with cytosine. This forms the complementary base pairs that make up the double helix structure of DNA.
What are the rules for binding on the double helix?
the DNA base pairs must be compliment and the strand must be exact opposite of the other.
The twisted ladder shape of the dna is called?
The twisted ladder shape of DNA is called a double helix.carbohydrate
Single helix is more stable as compared to the double helix?
The double helix of DNA is more stable than a single helix due to the hydrogen bonding between complementary base pairs and the structural support provided by the sugar-phosphate backbone. The double helix structure allows for efficient storage and replication of genetic information.
How many bases does a double helix have after the complementary strand is added?
A double helix has twice the number of bases in one strand, so after adding the complementary strand, the double helix will have the sum of the bases in both strands. This is because each base pairs with its complementary base (A with T, and G with C) across the two strands.
