I Believe the answer is sequence of nitrogen bases.
70 Year old woman in 5th Grade , i think i know this.
can somebody answer please
Thymine will always bond with adenine, and guanine will always bind with cytosine.
Two strands of DNA are held together by Hydrogen Bond, an attraction, between their nitrogen bases. There are 3 Hydrogen bond between Guanine and Cytosine, whereas 2 hydrogen bond between Adenine and Thymine. Remember the DNA runs in an anti-parallel direction. :)
The length of nitrogen-to-nitrogen bond is approx. 100 pm.
Nucleic Acid
The nitrogen bases are held together by hydrogen bonds.
Covalent bond
Complementary sequences of DNA, which pair the nucleotide base adenine with thymine, and cytosine with guanine, are held together by hydrogen bonds. The nucleotide bases are partially made up of nitrogen, oxygen and hydrogen molecules bonded together. On each base, one nitrogen is bonded to a hydrogen. Nitrogen is very electronegative, meaning that it pulls hydrogen's electron closer to it and becomes slightly negative. This leaves a slightly positive hydrogen sticking out. Each base also has an oxygen sticking out with a pair of electrons ready for bonding. These electrons can not bond with hydrogen, as hydrogen is already in a bond with nitrogen and can only form one bond. However, they are negatively charged and strongly attract the slightly positive hydrogen on the opposite complimentary base. This pattern means that two hydrogen bonds are formed each pair of complementary bases, holding complementary sequences together.
hydrogen bond
Hydrogen bonding
Three covalent bonds. One sigma bonds and two pi bonds. This is why many explosives, many containing nitrogen, are powerful. Nitrogen's triple bond holds a lot of energy
can somebody answer please
it is complimentary to thymine. it forms a double bond with thymine.
Nitrogen is not a bond; it is the single element Nitrogen.
This bond is covalent.
Hydrogen bonding holds together the two strands of a double stranded DNA. Hydrogen bonding exists between the nitrogen base pairs.
The hydrogen bonds between the comlementary nitrogen bases and the hydrophobic interactions between the adjascent base pairs held the DNA molecule in its exact shape.
