The 5' end of a DNA strand refers to the end where the phosphate group is attached to the 5th carbon of the sugar molecule, while the 3' end is where the hydroxyl group is attached to the 3rd carbon of the sugar molecule. This difference in chemical structure affects how DNA is synthesized and read by cells.
The 5' end of a DNA strand refers to the end with a phosphate group attached to the 5th carbon of the sugar molecule, while the 3' end has a hydroxyl group attached to the 3rd carbon. This difference in chemical structure affects how DNA is read and replicated.
During DNA replication, the template strand is used as a guide to create a complementary copy, while the coding strand is not directly involved in the copying process. The template strand determines the sequence of nucleotides in the new DNA strand, while the coding strand has the same sequence as the RNA transcript that will be produced from the new DNA strand.
The 3' end of a DNA strand has a free hydroxyl group on the third carbon of the sugar molecule, while the 5' end has a phosphate group attached to the fifth carbon. This structural difference affects how enzymes interact with the DNA during processes like replication and transcription.
The 5' prime end of DNA refers to the end of the DNA strand where the phosphate group is attached to the 5' carbon of the sugar molecule. The 3' prime end refers to the end where the hydroxyl group is attached to the 3' carbon of the sugar molecule. These differences in chemical structure affect how DNA strands are synthesized and replicated.
The key difference between 5' and 3' DNA strands is the direction in which the nucleotides are arranged. In a 5' DNA strand, the nucleotides are arranged from the 5' end to the 3' end, while in a 3' DNA strand, the nucleotides are arranged from the 3' end to the 5' end. This impacts genetic processes because DNA replication and transcription occur in a specific direction, with enzymes moving along the DNA strand in a 5' to 3' direction. The orientation of the DNA strand determines the direction in which these processes can occur, affecting how genetic information is copied and expressed.

DNA molecules. A strand of DNA molecules can be cut to have blunted ends or jagged ends (sticky ends).

The molecule that seals the gaps between the pieces of DNA in the lagging strand is DNA ligase. DNA ligase is an enzyme that catalyzes the formation of phosphodiester bonds between adjacent DNA fragments, joining them together to create a continuous strand.
The replication is semiconservative. Each strand acts as a template for the synthesis of a new DNA molecule by the sequential addition of complementary base pairs, thereby generating a new DNA strand that is the complementary sequence to the parental DNA. Each daughter DNA molecule ends up with one of the original strands and one newly synthesized strand.
One can differentiate between single-strand DNA and double-strand DNA by treating with exonuclease I which specifically digests only ssDNA. Note. For verification, the products have to be run on polyacrylamide gels with appropriate controls.

DNA polymerase is the enzyme that links DNA nucleotides to a growing daughter strand during DNA replication. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the new DNA strand.
The template strand, if reffering to DNA, is the strand of the DNA that is copied to make more DNA.
The complementary base pairing between adenine and thymine, and between cytosine and guanine, allows the old strand and the new strand of DNA to come back together during DNA replication. This pairing ensures the accurate synthesis of the new DNA strand.
