Molecular mechanism of DNA replication - Khan Academy
During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging strand) is made in small pieces. DNA replication requires other enzymes in addition to …
Leading and lagging strands in DNA replication - Khan Academy
DNA replication is a precise process where DNA unwinds and splits into two strands. Each strand then serves as a template for a new DNA molecule. The leading strand is built continuously, while the …
DNA replication (article) | Khan Academy
Leading Strand Synthesis: The leading strand is synthesized continuously (in one long piece) as nucleotides are added in the 5’ to 3’ direction moving toward the unwinding replication fork. Only one …
DNA structure and replication review (article) | Khan Academy
This is not the case. DNA polymerase only synthesizes DNA in the 5’ to 3’ direction only. The difference between the leading and lagging strands is that the leading strand is formed towards replication fork, …
Telomeres and telomerase (article) | Khan Academy
The other strand is produced in many small pieces called Okazaki fragments, each of which begins with its own RNA primer, and is known as the lagging strand. (See the article on DNA replication for more …
Leading and lagging strands in DNA replication - Khan Academy
On the leading strand, DNA polymerase catalyzes the continuous synthesis of DNA in the 5' to 3' direction. However, on the lagging strand, DNA synthesis occurs in short fragments called Okazaki …
Stages of transcription: initiation, elongation ... - Khan Academy
During elongation, RNA polymerase "walks" along one strand of DNA, known as the template strand, in the 3' to 5' direction. For each nucleotide in the template, RNA polymerase adds a matching …
DNA proofreading and repair (article) | Khan Academy
Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair. If DNA gets damaged, it can be repaired by various mechanisms, …

Chromosomes and genes (article) | Khan Academy
The leading strand is synthesized continuously in the 5' to 3' direction, while the lagging strand is synthesized discontinuously in small fragments called Okazaki fragments.
