In a second step, the researchers heated the ground cytosine and guanine powders. "At about 200 degrees Celsius, we could indeed observe the formation of cytosine-guanine pairs," reports Stolar.

In the strands, each nucleobase pairs with a complementary partner in the other strand: adenine with thymine and cytosine with guanine. "Only specific pairing combinations occur in the DNA, but ...

However, sometimes, cytosines can pair with each other, rather than with guanine. This causes a DNA molecule to twist in on itself, creating a four-stranded, protruding structure called an i-motif.

Normally, the genetic code consists of four nucleotide bases: adenine (A), cytosine (C), guanine (G) and thymine (T). In DNA, guanine always pairs with cytosine and adenine with thymine.

Thus, Guanine pairs with Cytosine, and Thymine with Adenine. The team at the University of Georgia studied how the removal of a proton from the Guanine-Cytosine (G-C) ...

The specific base-pairing interactions between nucleobases are the foundation of the storage and transmission of genetic information. In DNA, adenine always pairs with thymine (A-T), and guanine ...

These four molecular bases—adenine, thymine, cytosine and guanine—pair with each other using hydrogen bonds to form the foundation for a DNA strand.

This pairing is very specific: adenine pairs with thymine and cytosine pairs with guanine. This selective pairing is called ‘complementary base pairing’. A-T pair forms two hydrogen bonds ...

The first report of a bacterium whose genome contains man-made DNA building blocks opens the door for tailor-made organisms that could be used to produce new drugs and other products.

Normally, the genetic code consists of four nucleotide bases: adenine (A), cytosine (C), guanine (G) and thymine (T). In DNA, guanine always pairs with cytosine and adenine with thymine.

Adenine pairs with thymine, while guanine pairs with cytosine. However, sometimes, cytosines can pair with each other, rather than with guanine. This causes a DNA molecule to twist in on itself, ...
