How can one determine which end is 3' and which end is 5' in a DNA molecule?
In a DNA molecule, the end with the 3' designation has a free hydroxyl group on the third carbon of the sugar molecule, while the end with the 5' designation has a free phosphate group on the fifth carbon of the sugar molecule. This can be determined by examining the structure of the DNA molecule.
What is located at the 3' end of DNA?
At the 3' end of DNA, there is a hydroxyl group attached to the third carbon of the sugar molecule in the DNA strand.
How does the process of DNA replication ensure that the number of base pairs in a DNA molecule goes from 3 to 5?
During DNA replication, the enzyme DNA polymerase adds new nucleotides to the 3' end of the growing DNA strand. This ensures that the number of base pairs in a DNA molecule increases from 3 to 5, as the new nucleotides are added in the 5' to 3' direction.
What is located on the 3' end of DNA?
The 3' end of DNA contains a hydroxyl group (-OH) on the sugar molecule of the nucleotide.
What are the differences between the 5' and 3' ends of DNA molecules?
The 5' end of a DNA molecule refers to the end where the phosphate group is attached to the 5' carbon of the sugar molecule in the DNA backbone. The 3' end, on the other hand, is where the hydroxyl group is attached to the 3' carbon of the sugar molecule. This difference in chemical structure affects how DNA is synthesized and replicated.

When one dna molecule replicated the result is two dna molecules what is true of the second dna molecule?
DNA actually has 3 forms. A-DNA, B-DNA, and Z-DNA. B-DNA is the kind you are most familiar with and present in most organisms. A-DNA can be found in dehydrated samples while Z-DNA is rare and mostly synthesized in the lab.
What end of the DNA molecule allows the best access for DNA polymerase during replication?
3'OH end 3'OH end
Reverse transcription 5' to 3'?
Reverse transcription is the process of synthesizing a DNA molecule from an RNA template. In this process, a reverse transcriptase enzyme catalyzes the formation of DNA nucleotides in the 5' to 3' direction, complementary to the RNA template. This results in the creation of a DNA molecule that is a copy of the original RNA molecule.
What part of a DNA molecule is responsible for the genetic code?
The genes present in a DNA molecule are responsible for the genetic code. Within the genes, the exons specifically are the coding regions.
What is the 3-d dimensional shape of the DNA molecule called?
double helix
Three thing make the structure of a DNA molecule?
The structure of a DNA molecule is made up of three things: a sugar-phosphate backbone, nucleotide bases (adenine, thymine, cytosine, and guanine), and hydrogen bonds that form between the bases. These components form the double helix shape of the DNA molecule.
