DNA polymerase
DNA polymerase attaches to the DNA strand at a specific region called the origin of replication. This is where the double-stranded DNA is unwound, creating two template strands for DNA synthesis to occur. DNA polymerase then begins replicating the DNA in a 5' to 3' direction.
Ligase joins okazaki fragments to each other to form a continuous strand of DNA
DNA replication is a semi-conservative process. The DNA is split into two strands. Nucleotides are then attached to each strand by complementary base pairing, where A attaches to T and G attaches to C. The newly formed strand is hence identical to the old strand and the base sequence of DNA can hence be conserved during replication.
The complementary DNA sequence to CTA is GAT. In DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). So, for every C in one strand, there should be a G in the complementary strand, and for every T in the original strand, there should be an A in the complementary strand.
DNA polymerase
During DNA replication, DNA polymerase binds free DNA nucleotides to an unzipped DNA strand. During transcription, RNA polymerase binds free RNA nucleotides to the unzipped anti-sense DNA strand.
DNA polymerase attaches to the DNA strand at a specific region called the origin of replication. This is where the double-stranded DNA is unwound, creating two template strands for DNA synthesis to occur. DNA polymerase then begins replicating the DNA in a 5' to 3' direction.
The enzyme responsible for extending the new DNA strand by adding nucleotides is DNA polymerase. It reads the template strand and adds complementary nucleotides to form a new DNA strand. DNA polymerase can only add nucleotides in the 5' to 3' direction.

DNA polymerase attaches (polymerizes) nucleotides together to make polynucleotides using a strand of DNA that has already been unzipped by DNA helicase.
Helicase attaches to the DNA strand at the replication fork, which is the region where the double-stranded DNA is unwound to separate the two strands during DNA replication. Helicase helps to unzip the double helix by breaking hydrogen bonds between the base pairs.
The enzyme responsible for attaching new nucleotides to the open strand of DNA is called DNA polymerase. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the growing DNA strand during DNA 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.
RNA polymerase attaches to unwound DNA during transcription by recognizing and binding to specific promoter sequences on the DNA strand. Once bound, the RNA polymerase begins to synthesize a complementary RNA strand using the DNA template.
