How many nitrogen base pairs are present in one strand of human DNA?
There are about 3 billion nitrogen base pairs present in one strand of human DNA.
Where is the 5' end of the DNA strand indicated?
The 5' end of a DNA strand is indicated by the phosphate group attached to the 5th carbon of the sugar molecule in the nucleotide.
Why is there always a phosphate group on the 5' end of a DNA strand and not the 3' end?
The phosphate group is added to the 5' end of a DNA strand during DNA synthesis because the nucleotides are joined together from the 5' to 3' direction. This forms a bond between the 3' OH group of one nucleotide and the 5' phosphate group of another, creating a phosphodiester bond. The 3' end of the DNA strand remains with a free hydroxyl group, which is essential for further DNA synthesis.
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.
What is the term for the 5' DNA strand?
The term for the 5' DNA strand is the leading strand.
How many nitrogen base pairs are present in one strand of human DNA?
There are about 3 billion nitrogen base pairs present in one strand of human DNA.
What does a single strand of DNA bind to in the phosphate group?
The 5 prime end of the strand.
What molecule is found on the 3' DNA strand?
The molecule found on the 3' end of a DNA strand is a hydroxyl group (-OH) attached to the 3' carbon of the deoxyribose sugar. This hydroxyl group is crucial for DNA polymerization during replication, as it provides a site for the addition of nucleotides. In contrast, the 5' end of the DNA strand features a phosphate group attached to the 5' carbon of the sugar.
Where is the 5' end of the DNA strand indicated?
The 5' end of a DNA strand is indicated by the phosphate group attached to the 5th carbon of the sugar molecule in the nucleotide.
What is the PO3 functional group?
ATP, DNA, and phospholipids
What is the strand?
The template strand, if reffering to DNA, is the strand of the DNA that is copied to make more DNA.

What strand of DNA would be prod from the template strand of DNA shown below?
The complementary strand of DNA to the template strand TACGGCTA would be ATGCCGAT.
Why are ddNTPs used for DNA sequencing?
ddNTPs, or dideoxynucleotide triphosphates, are used in DNA sequencing because they lack a 3' hydroxyl group, which prevents further DNA strand elongation when they are incorporated into the growing DNA strand. This allows for the determination of the sequence of nucleotides in the DNA template.
How are nucleotides added to the 3' end of a DNA strand during replication?
During DNA replication, nucleotides are added to the 3' end of a DNA strand by an enzyme called DNA polymerase. This enzyme attaches new nucleotides to the existing strand in a complementary manner, following the base pairing rules (A with T, and G with C). The 3' end of the DNA strand provides a free hydroxyl group (-OH) that allows the DNA polymerase to add the new nucleotide, extending the DNA strand in the 5' to 3' direction.
