What nitrogenous base makes sugar phosphate group?
What nitrogenous base makes sugar phosphate group?
Deoxyribonucleic acid (DNA)
Deoxyribonucleic acid (DNA) is made up of sugar, a nitrogenous base and a phosphate group (Figure 1.2). The combination of these molecules makes the building blocks for the DNA synthesis.
What is a 5 carbon sugar nucleotide?
The five-carbon sugar in DNA is called deoxyribose, while in RNA, the sugar is ribose.
What base attaches to the 5 carbon sugar?
The sugar is the 3′ end, and the phosphate is the 5′ end of each nucleiotide. The phosphate group attached to the 5′ carbon of the sugar on one nucleotide forms an ester bond with the free hydroxyl on the 3′ carbon of the next nucleotide.
Is the phosphate group on the 5 carbon?
Phosphodiester bonds make up the backbones of DNA and RNA. The phosphate is attached to the 5′ carbon. The 3′ carbon of one sugar is bonded to the 5′ phosphate of the adjacent sugar.
What is the name of the 5 carbon sugar in RNA?
Ribose
Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules. Note the absence of the hydroxyl (-OH) group on the 2′ carbon in the deoxy-ribose sugar in DNA as compared with the ribose sugar in RNA.
Which carbon on the deoxyribose sugar is attached to the 5 phosphate in a nucleotide?
The phosphate group is attached to the 5′ carbon of one nucleotide and the 3′ carbon of the next nucleotide. In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases.
What is the bond between sugar and phosphate?
covalent bond
The bond formed between the sugar of one nucleotide and the phosphate of an adjacent nucleotide is a covalent bond. A covalent bond is the sharing of electrons between atoms. A covalent bond is stronger than a hydrogen bond (hydrogen bonds hold pairs of nucleotides together on opposite strands in DNA).
What group is phosphorus in?
group 15
Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table. This element exists in several forms, of which white and red are the best known.
Which monomer is made up of a nitrogenous base and five-carbon sugar?
A monomer made up of a nitrogenous base, a five-carbon sugar, and a phosphate group bonded together. Explanation; -Nucleic acids such as DNA and RNA are made up of chains of many repeating units called nucleotides. Nucleotides are made up of a 5-carbon sugar(deoxyribose),a phosphate group and a nitrogenous base bound to the sugar .
Does DNA have nitrogen base and phosphate?
Both DNA and RNA are composed of nucleotides, each of which contains a five-carbon sugar, a nitrogen base, and a phosphate group. Where is Nitrogen family located at the periodic table?
Where is the sugar-phosphate backbone located in a helix?
The sugar-phosphate backbone is on the outside of the helix where the polar phosphate groups (red and yellow atoms) can interact with the polar environment. The nitrogen (blue atoms) containing bases are inside, stacking perpendicular to the helix axis.
How many nitrogen bases are in a nucleotide?
A nucleotide is composed of a 5-carbon sugar, a phosphate group, and one of four nitrogen bases. Is the amino group composed of one nitrogen and two hydrogen atoms?
