Why is there always a phosphate group on the 5' end of a DNA strand and not the 3' end?

there is no bonding point for the phosphate group on the 3' side of the sugar. There is a hydroxide there instead

What are the two chemical groups that form the backbone of a DNA strand?
Deoxiribose and phosphate.
DNA how do you tell if a DNA strand begins with the 5 prime or the 3 prime?
The 5 prime end of DNA has phosphate group while the 3 prime end has a hydroxyl group.
Which of the following statements about the 5' end of a polynucleotide strand of DNA is correct?
The 5' end has a phosphate group attached to the number 5 carbon of ribose.
What are 3 things a nucleotide is made up of?
the three components that make up a nucleotide are a phosphate,deoxyribose and a nitrogen base
What three components make up a dna nucleotide?
Out of these options: cytidine, phosphate group, ribose Guanine, phosphate group, ribose adenine, phosphate group, ribose cytosine, phosphate group, ribose deoxyribose, phosphate group, thymine deoxyribose, phosphate group, uracil The answer is: deoxyribose, phosphate group, thymine
What does a single strand of DNA bind to in the phosphate group?
The 5 prime end of the strand.
In a single strand of dna the phosphate group binds to what?
It binds to a Deoxyribose sugar. Thus, the structure of DNA is Phosphate-Deoxyribose-Nitrogenous Base.
What are the two chemical groups that form the backbone of a DNA strand?
Deoxiribose and phosphate.
What chemical group is at the end of the 5 prime end of DNA strand?
5' - phosphate group 3' - hydroxyl group
DNA how do you tell if a DNA strand begins with the 5 prime or the 3 prime?
The 5 prime end of DNA has phosphate group while the 3 prime end has a hydroxyl group.
Is the 5 prime end of DNA charged?
Yes. The 5' end of a DNA strand ends in a phosphate group. At physiological pH values, this group has a charge of -2. The other phosphate groups along the sugar-phosphate backbone have a charge of -1 each.
What are the handrails of the DNA strand made of?
Deoxyribose (Sugar) and a Phosphate
What are the components of genetics materials?
Deoxyribonucleicacids(DNA). DNA is composed of a 5 carbon sugar called deoxyribose which is bonded to a phosphate group and a nitrogenous base. Many of these linked together create a DNA strand
Is a nucleotide a phosphate sugar nitrogen base?
In a nucleotide the 5-carbon sugar is bonded to the phosphate group, which is bonded to the nitrogenous base. In a chain of nucleotides (a strand of DNA), the nucleotides are connected by covalent bonds between the sugar of one nucleotide, and the phosphate group of the next nucleotide.
Which of the following statements about the 5' end of a polynucleotide strand of DNA is correct?
The 5' end has a phosphate group attached to the number 5 carbon of ribose.
What are the handrails of each DNA strand are made up of?
Deoxyribose (Sugar) and a Phosphate
Does RNA contain a phosphate group like DNA?
yes , it contains a phosphate group.
