Summary
Artificial gene synthesis using overlap extension PCR can be optimized. A new method, Asymmetric Extension supported by a Simulator for Oligonucleotide Extension (AESOE), enhances DNA synthesis efficiency by controlling oligomer direction.
Area of Science:
- Molecular Biology
- Synthetic Biology
- Biotechnology
Background:
- Overlap extension PCR is a common method for artificial gene synthesis.
- This process often generates numerous intermediate synthetic products.
- Optimizing oligomer concentration and orientation is crucial for efficiency.
Purpose of the Study:
- To develop an optimized method for artificial gene synthesis.
- To reduce intermediate product formation in DNA synthesis.
- To improve the efficiency and speed of full-length DNA synthesis.
Main Methods:
- Utilized a simulation program for serial oligomer extension.
- Investigated the effect of oligomer orientation and concentration.
- Introduced a novel method named Asymmetric Extension supported by a Simulator for Oligonucleotide Extension (AESOE).
Main Results:
- Predicted optimal efficiency with a 'forward-reverse-reverse-reverse' oligomer orientation.
- Demonstrated shortest synthesis time (number of cycles) using designed oligomer directions.
- AESOE method showed high efficiency and effectiveness in DNA synthesis.
Conclusions:
- The AESOE method significantly improves artificial gene synthesis.
- Optimized oligomer direction is key to efficient DNA synthesis.
- AESOE has potential for further improvements and widespread application in DNA synthesis.

Lagging Strand Synthesis
60.4K
During replication, the complementary strands in double-stranded DNA are synthesized at different rates. Replication first begins on the leading strand. Replication starts later, occurs more slowly, and proceeds discontinuously on the lagging strand.
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...

DNA Replication
57.5K
DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied. After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

Proofreading
8.4K
Synthesis of new DNA molecules is carried out by the enzyme DNA polymerase, which adds nucleotides on the daughter strand complementary to the template DNA strand. DNA polymerase has a higher affinity to add the correct base and ensures fidelity during DNA replication. Furthermore, it exhibits proofreading activity during replication, using an exonuclease domain that cuts off incorrect nucleotides from the nascent DNA strand.
