What type of bond between nitrogen base pyrimidine and pentose sugar?
The bond between a pyrimidine nitrogen base and a pentose sugar in DNA or RNA is a glycosidic bond. This bond forms between the carbon atoms of the nitrogenous base and the carbon atoms of the pentose sugar.
What part of the DNA backbone do nitrogen bases bond to?
Nitrogen bases in DNA bond to the deoxyribose sugar molecules that make up the DNA backbone. The bond between the sugar and the base is a covalent bond known as a glycosidic bond.
Which nitrogen base bonds with adenine?
Thymine will always bond with adenine, and guanine will always bind with cytosine.
What pairing holds together two strands on DNA?
Hydrogen bonds hold together two strands of DNA. These bonds form between complementary nitrogenous bases on each strand, such as adenine (A) pairing with thymine (T), and cytosine (C) pairing with guanine (G).
What nitrogenous bases will tend to hydrogen bond with adenine in DNA?
Thymine will tend to hydrogen bond with adenine in DNA due to complementary base pairing. In RNA, uracil can also hydrogen bond with adenine.
What type of bond holds the base pair together?
The nitrogen bases are held together by hydrogen bonds.
In what way do the nitrogen bases bond?
Nitrogen bases in DNA bond through hydrogen bonds. Adenine pairs with thymine, and guanine pairs with cytosine, creating complementary base pairs that hold the two strands of the DNA double helix together.
What type of bond holds the two atoms of nitrogen together in the nitrogen gas?
A triple covalent bond holds the two nitrogen atoms together in a molecule of nitrogen gas (N2). Each nitrogen atom contributes three of its valence electrons to share with the other nitrogen atom, resulting in a very stable bond due to the multiple shared electrons.
How are complementary sequences held together?
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.
What bond exist between each nitrogen base?
hydrogen bond
What type bond occur during complementary base pairing?
Hydrogen bonding
What nitrogen base most closely resembles cytosine and why?
Thymine most closely resembles cytosine because they both have a single-ring structure (pyrimidine) and are hydrogen bond complementary bases in DNA.
What type of bond between nitrogen base pyrimidine and pentose sugar?
The bond between a pyrimidine nitrogen base and a pentose sugar in DNA or RNA is a glycosidic bond. This bond forms between the carbon atoms of the nitrogenous base and the carbon atoms of the pentose sugar.
What are complementary base pairs and can you provide an example?
Complementary base pairs are nucleotide bases in DNA that always bond together in a specific way: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). An example of complementary base pairs is A-T and C-G.
What part of the DNA backbone do nitrogen bases bond to?
Nitrogen bases in DNA bond to the deoxyribose sugar molecules that make up the DNA backbone. The bond between the sugar and the base is a covalent bond known as a glycosidic bond.
Region of nucleotide to which the nitrogen base is attached in DNA?
The nucleotide to which the nitrogen base is attached in DNA is the sugar molecule, specifically the deoxyribose sugar. The nitrogen base is attached to the 1' carbon of the deoxyribose sugar through a glycosidic bond.
What is the bonding which holds hydrogen and nitrogen?
Hydrogen and nitrogen are typically held together by a covalent bond in molecules such as ammonia (NH3) or hydrazine (N2H4). This bond involves the sharing of electrons between the hydrogen and nitrogen atoms to form a stable molecule.
