What electric charge do the phosphate groups in DNA have?
A negative charge, as do all phosphate groups.
What type of bonds holds the sugar and phosphate groups together?
Phosphodiester bonds hold the sugar and phosphate groups together in DNA and RNA molecules. These bonds form between the phosphate group of one nucleotide and the 3'-hydroxyl group of the sugar in the adjacent nucleotide.
What is the Sugar phosphate backbone of the DNA?
THE BACKBONE OF DNA IS FORMED OF NUCLEOTIDES LINKED BY PHOSPHODIESTER BOND.A nucleotide consists of following three compounds1. Pentose sugar :- It is a 5 membered ring sugar. Out of these 5 members four are carbon and one is oxygen. The pntose sugar in case of DNA is deoxyribose.2. Nitrogen Base :- It is a nitrogen containg basic ring compound. They are broadly classified into 2 categories-Pyrines and pyrimidines. These are further divided into 5 nitrogen bases. They are Adenine,Guanine,Cytocine, Thymine, Uracil. Out of these 5 bases only four are present in DNA and only one occurs in it at a time.DNA does not have Uracil. The 7th or 9th nitrogen of the nitrogen base are linked to the 1st carbon of pentose sugar by glycosidic bond3. Phosphate group :-It is a derivative of phosphoric acid and is attached to 5th carbon of pentose sugar by ester bond formed by dehydration synthesisTwo nucleotides in DNA are liked by phospho diester bond formed between -OH of phosphate group of one nucleotide and 3rd carbon of pentose sugar ofadjacent nucleotide.
What is the function of phosphate group in DNA nucleotides?
Phosphate groups in DNA nucleotides provide a negative charge that allows DNA strands to repel each other, contributing to the stability of the double helix structure. They also serve as a linkage between adjacent nucleotides in the DNA strand, forming the backbone of the DNA molecule. Additionally, phosphate groups are involved in the process of DNA replication and transcription.
Is the sides of the DNA molecule are made up of repeating nitrogen bases and sugars?
The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.
What type of bond is found between the phosphate groups?
In DNA, the phosphate groups are connected by phosphodiester bonds, which are covalent bonds formed between a phosphate group and two adjacent nucleotides in the DNA backbone.
Does Deoxyribose bond to phosphate in DNA?
Yes, deoxyribose sugar molecules in DNA form covalent bonds with phosphate groups to create the sugar-phosphate backbone of the DNA molecule. This alternating sugar-phosphate backbone provides stability and support to the DNA double helix structure.
Where are phosphate groups in a DNA molecule?
The DNA backbone, are made of alternating sugars and phosphate groups.
Is there phosphate groups found in DNA?
The DNA backbone, are made of alternating sugars and phosphate groups.
What 2 substances make up the backbone or the sides of the DNA molecule?
The sugar-phosphate backbone of DNA is made up of deoxyribose (a sugar) and phosphate.
Why is DNA negatively charged?
DNA is negatively charged because of the phosphate group that is in each nucleotide. DNA also has a negative charge because of the phosphate icons in its chemical "backbone".
Where are the high energy bonds found in ATP?
between phosphate groups
What electric charge do the phosphate groups in DNA have?
A negative charge, as do all phosphate groups.
Do the rungs of DNA connect to phosphate or sugar?
Sugar. The backbone of the DNA molecule is composed of ribose and phosphate, but the bases which make up the "rungs" of DNA are always connected to the sugar. The phosphate is used to bond the sugars together into long strings.
What is the relationship between a phosphate base and sugar in the structure of DNA?
In the structure of DNA, a phosphate base is connected to a sugar molecule through a covalent bond. This bond forms the backbone of the DNA molecule, with the phosphate-sugar backbone providing stability and structure to the double helix shape of DNA.
Are phosphate groups part of a DNA molecule?
Yes
The bond that holds the DNA sugars together to form the backbone of DNA is?
Phosphate backbone
