Proofreading

Proofreading

Synthesis of new DNA molecules starts when DNA polymerase links nucleotides together in a sequence that is complementary to the template DNA strand. DNA polymerase has a higher affinity for the correct base to ensure fidelity in DNA replication. The DNA polymerase furthermore proofreads during replication, using an exonuclease domain that cuts off incorrect nucleotides from the nascent DNA strand.Errors during Replication Are Corrected by the DNA Polymerase EnzymeGenomic DNA is synthesized in...

Proofreading

Proofreading

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.

Improving Translational Accuracy

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Translation

Translation

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
Translation Produces the Building Blocks of Life

Summary

Using multiple large language models (LLMs) for title-and-abstract screening in systematic reviews shows promise. A full agreement approach with three LLMs automates decisions effectively, reducing screening burden.

Area of Science:

Bibliometrics
Information Science
Medical Informatics

Background:

Exponential growth in scientific literature complicates systematic reviews.
Title-and-abstract screening is a labor-intensive bottleneck in systematic reviews.

Purpose of the Study:

To evaluate the feasibility of using multiple large language models (LLMs) for title-and-abstract screening.
To assess a full-agreement approach for automated screening decisions.

Main Methods:

Employed a full-agreement strategy using three distinct LLMs (ChatGPT, Gemini, Claude).
Automated decisions were accepted only when all three LLMs reached consensus.
Evaluated across six datasets with a structured workflow and performance stop criterion.

Main Results:

Approximately 80% of abstracts achieved full agreement across the three LLMs.
Automated classification for the agreed subset demonstrated superior performance compared to previous LLM methods.
Statistically significant improvements were observed in all prespecified performance metrics.

Conclusions:

A full-agreement approach using multiple LLMs offers a conservative strategy for systematic review screening.
This method automates concordant decisions, reserving human review for discordant cases.
The findings support this approach for reducing screening burden, though generalizability needs further study.
