Concerns regarding the present mode of education and teaching quality in institutions of higher learning in India have been expressed recently in Current Science. This can also be a warning for the education in colleges and schools, where teaching is performed by university degree holders. Both teaching and research are important requirements in the institutions of higher learning to produce quality human resources, as well as to sustain development. An imbalance between the two will affect the progress.Full Text

In the genetic code table, out of the 64 triplet codons, generally 61 codons are involved in coding for the 20 amino acids in organisms. Therefore, the genetic code table is an obvious degenerate: except Met and Trp, each of the 18 amino acids is coded by 2-6 synonymous codons. Synonymous codons (Box 1) not only encode the same amino acid, but are similar to each other with regard to their nucleotide sequences as well as distribution in the table. Therefore, study of these codons in different genomes has been of great interest to molecular evolutionary biologists.Full Text

The Guest Editorial regarding borders in science and nations by Arunan is pertinent in the present context. Though artificial borders are occasionally important, creating a border because of personal greed or jealousy must be avoided. The history of partition of our country is a well-known example. India is a vast country with differences among the people with regard to their language, culture, religion, appearance and habits, which provide avenues for the creation of artificial borders.Full Text

In our study, we compared synonymous polymorphism in co-transcribed gene pairs within five well-known Escherichia coli operons (rpoB/C, lacZ/Y, kdpA/B, araB/A and bcsA/B). Interestingly, the transition to transversion ratio between gene pairs were different due to their compositional differences of two-fold and four-fold degenerate codons. The differences in polymorphism spectra were more pronounced in four-fold and six-fold codons compared to two-fold degenerate codons. Notably, rpoB and rpoC showed significant distinctions in UCC, GUA, CCG, GCU, GGC and CGC codons. Similar trends were observed in other gene pairs, particularly in higher degenerate codons. Notably, two-fold degenerate codons primarily exhibited synonymous polymorphisms through transitions, while higher degenerate codons encompassed both transition and transversion events. This underscores the intriguing role of degenerate codons in molecular evolution.Keywords
