How is the lagging strand different from the leading strand during DNA replication?

Show
The leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction. The leading strand is synthesized by adding nucleotides to the 3' end of the growing strand, and the lagging strand is synthesized by adding nucleotides to the 5' end. The lagging strand is synthesized continuously, whereas the leading strand is synthesized in short fragments that are ultimately stitched together. The leading strand is synthesized at twice the rate of the lagging strand. 14. DNA Replication 1 conceptLeading & Lagging DNA Strands 5m Play a video: The leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction. The leading strand is synthesized by adding nucleotides to the 3' end of the growing strand, and the lagging strand is synthesized by adding nucleotides to the 5' end. The lagging strand is synthesized continuously, whereas the leading strand is synthesized in short fragments that are ultimately stitched together. The leading strand is synthesized at twice the rate of the lagging strand. one RNA primer attaches to the 5' end of the parent strand and the other primer to the 3' end. Both daughter strands can't extend toward the replication fork because there would not be room for two DNA polymerase enzymes. Both RNA primers attach to the 3' end of the template strands, which are at opposite ends from each other. The DNA strands run antiparallel to each other and the DNA polymerase can only add nucleotides to the 3' end of the growing strand. A is the lagging strand, as DNA is always synthesized in the 5' to 3' manner. B is the lagging strand, as DNA is always synthesized in the 5' to 3' manner. A is the lagging strand, as DNA is always synthesized in the 3' to 5' manner. B is the lagging strand, as DNA is always synthesized in the 3' to 5' manner. It is impossible to tell, with the information provided. Posted July 22, 2020The leading strand and lagging strand are the two strands at the replication fork, which serve as the templates for DNA replication. The leading strand is the strand of nascent DNA which is synthesized in the same direction as the growing replication fork. The synthesis of leading strand is continuous. The lagging strand, on the other hand, is the strand of new DNA whose direction is opposite to the direction of the growing replication fork. Replication of the lagging strand is more complicated than that of the leading strand. It is synthesized in short, separated segments, which are then joined together by DNA ligase to form a continuous DNA strand.

Delete ContentDNA replication of the leading and lagging strand The helicase unzips the double-stranded DNA for replication, making a forked structure. The primase generates short strands of RNA that bind to the single-stranded DNA to initiate DNA synthesis by the DNA polymerase. This enzyme can work only in the 5' to 3' direction, so it replicates the leading strand continuously. Lagging-strand replication is discontinuous, with short Okazaki fragments being formed and later linked together. This image is linked to the following Scitable pages:
The decoding of information in a cell's DNA into proteins begins with a complex interaction of nucleic acids. Learn how this step inside the nucleus leads to protein synthesis in the cytoplasm.
Save NoteWhat is the difference between the leading strand and the lagging strand in DNA replication quizlet?The leading strand is synthesized continuously in the 5' → 3' direction, while the lagging strand is synthesized discontinuously in the 5' → 3' direction. The leading strand requires an RNA primer, whereas the lagging strand does not.
What is the difference between the leading strand and the lagging strand in DNA replication What are Okazaki fragments and which strand are they formed on?The main difference between leading and lagging strand is that the leading strand is the DNA strand, which grows continuously during DNA replication whereas lagging strand is the DNA strand, which grows discontinuously by forming short segments known as Okazaki fragments.
What is the difference between the leading and lagging?If a leading indicator informs business leaders of how to produce desired results, a lagging indicator measures current production and performance. While a leading indicator is dynamic but difficult to measure, a lagging indicator is easy to measure but hard to change.
