A primer (oligonucleotide of a specific sequence) is required for Taq polymerase to extend the template strand by adding complementary nucleotides. The function of the primer is to anneal to the template strand at a very specific site and facilitate the initiation of strand elongation mediated by Taqploymerase.
Strand elongation is typically measured by comparing the length of the strand before and after stretching or extending. This can be done using instruments like a ruler, calipers, or specialized equipment for accurate measurements. The elongation is usually calculated as a percentage increase in length from the original strand dimension.
The template for semiconservative replication is the original DNA strand that serves as a guide for creating a new complementary strand. During DNA replication, each original parental strand acts as a template for the synthesis of a new daughter strand.
During DNA replication, one strand of the double helix serves as the template for synthesizing a new complementary strand. The enzyme DNA polymerase reads the template strand and adds nucleotides one by one, matching them with the appropriate bases (adenine with thymine, and cytosine with guanine). This process ensures that the genetic information is accurately copied and passed on to the daughter cells. The other strand, known as the lagging strand, is synthesized in short segments, which are later joined together.
DNA ligase plays a crucial role in the elongation of the lagging strand during DNA replication by sealing the nicks between the Okazaki fragments. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides, joining the fragments together to form a continuous strand. This ensures the completion of the synthesis of the lagging strand and the formation of a fully functional double-stranded DNA molecule.
which statement about dna replication is correct? A. the leading strand is one of the strands of parnetal Dna b. the leading strand is built continuously, and the lagging strand is built in pieces c. the lagging strand is one of the strands of parental Dna d. Dna ligase helps assemble the leading strand e. the lagging strand is built continuously

ssb protein bind to the lagging strand as leading strand is invovled in dna replication and lagging strand is invovled in okazaki fragment formation
Replication occurs in the 5' to 3' direction. The new DNA strand is synthesized in the 5' to 3' direction, while the parental template strand acts as the template for this synthesis. This directionality allows for continuous synthesis on one strand (leading strand) and discontinuous synthesis on the other strand (lagging strand).
The lagging strand will have the Okazaki fragments. These short fragments are created as the DNA replication machinery synthesizes the new DNA strand discontinuously in the 5'-3' direction away from the replication fork.
The lagging strand is called the lagging strand because, unlike the leading strand, DNA polymerase can not replicate in a 5' to 3' uninterrupted flow on this strand. Remember, DNA has two strands that run ANTIPARALLEL, one to the other; in other words they run in opposite directions.
One is known as the Leading strand, and the other is known as the Lagging strand.

The DNA strand that is copied to make mRNA is the template strand of the gene. This strand serves as a template for the RNA polymerase enzyme to synthesize a complementary mRNA strand during the process of transcription.
The complementary strand of DNA to the template strand TACGGCTA would be ATGCCGAT.
