We have constructed a zebrafish yeast artificial chromosome (YAC) library using genomic DNA isolated from the inbred AB zebrafish strain. The average insert size is 470 kb, estimated from analysis of 155 random selected YACs. The library consists of 17,000 clones, providing about a 4.7-fold coverage of zebrafish genome. The YAC clones have been arrayed in individual wells of 96-well microplates and also pooled to permit rapid polymerase chain reaction screening of the entire library. We have also found that the YAC ends can be easily rescued and sequenced from pRML1/pRML2-based mini-YAC clones. Copyright 1998 Academic Press.

Miltiradiene serves as a pivotal precursor for the synthesis of numerous abietane-type diterpenes with important pharmacological activities. The endogenous mevalonate (MVA) pathway is tightly regulated in Saccharomyces cerevisiae, which limits the availability of precursors for the heterologous production of miltiradiene. In this study, the orthogonal isopentenol utilization pathway (IUP) was constructed and investigated for its adaptability with mitochondria and peroxisomes in S.

Transfer RNAs (tRNAs) serve as a dictionary for the ribosome translating the genetic message from mRNA into a polypeptide chain. In addition to this canonical role, tRNAs are involved in other processes such as programmed stop codon readthrough (SC-RT). There, tRNAs with near-cognate anticodons to stop codons must outcompete release factors and incorporate into the ribosomal decoding center to prevent termination and allow translation to continue.

The cytological examination of urine samples can be done using the manual (microscopic) or automated technique. The automated approach, which involves the use of artificial intelligence, is faster, more reliable, and more efficient for laboratories.

Hybrid sweetgum (Liquidambar styraciflua × L. formosana) is a globally significant forest tree resource, exhibiting significant economic, ornamental, ecological and medicinal values. Somatic embryogenesis (SE) is an effective reproductive strategy, having great application potential and economic value in large-scale propagation, artificial seed production, genetic transformation, germplasm preservation and biotechnology.

Selective pressure acts on the codon use, optimizing multiple, overlapping signals that are only partially understood. We trained AI models to predict codons given their amino acid sequence in the eukaryotes and and the bacteria and to study the extent to which we can learn patterns in naturally occurring codons to improve predictions. We trained our models on a subset of the proteins and evaluated their predictions on large, separate sets of proteins of varying lengths and expression levels.
