What is the difference between continuous and discontinuous replication of DNA?
Differentiate between continuous and discontinuous synthesis of DNA….1 Answer.
| Continuous | Discontinuous |
|---|---|
| (a) One stand of DNA is synthesised as a continuous strech in the 5′ —>3′ direction. | (a) Short stretches are synthesised in the 5’—>3′ direction from replication fork |
What is the continuous and discontinuous replication of the two strands of a DNA molecule?
The enzyme involved in the process of replication is DNA dependent DNA polymerase. This enzyme catalyzes polymerization only in one direction, i.e., 5′ → 3′. As a result on template strand with 3′ → 5′ the replication is continuous while on the template strand with polarity 5’→3′ replication is discontinuous.
What is continuous and discontinuous synthesis?
The continuous branch describes the evolution of the plagioclase feldspars as they evolve from being calcium-rich to more sodium rich. The discontinuous branch describes the formation of the mafic minerals olivine, pyroxene, amphibole, and biotite mica.
Why DNA is replicated in a discontinuous way?
Replication of the lagging strand occurs in the direction away from the replication fork in short stretches of DNA, since access to the DNA is always from the 5′ end. This results in pieces of DNA being replicated in a discontinuous fashion.
What does continuous mean in DNA replication?
Continuous DNA Replication This means that the daughter strands must replicate in two different ways. For the ideally oriented strand, replication can occur continuously, progressing in the same direction as the replication fork, with nucleotides being added one by one.
What is discontinuous process?
adjective. A process that is discontinuous happens in stages with intervals between them, rather than continuously.
What does continuous replication mean?
On which strand of DNA replication is discontinuous?
lagging strand
Reconstitution experiments using replication proteins from a number of different model organisms have firmly established that, in vitro, DNA replication is semi-discontinuous: continuous on the leading strand and discontinuous on the lagging strand.
What is difference between continuity and discontinuity?
The continuity view says that change is gradual. Children become more skillful in thinking, talking or acting much the same way as they get taller. The discontinuity view sees development as more abrupt-a succession of changes that produce different behaviors in different age-specific life periods called stages.
What is continuous replication?
Is DNA replication discontinuous or semi-discontinuous?
Due to this reason, replication occurs continuously on one strand and discontinuously on the other strand. This is known as the semi-discontinuous mode of replication. Every new DNA molecule that is formed has a new and an old strand of the DNA. Thus, during DNA replication, entirely new DNA copies are not generated.
