SEA VIEW and PHYLO_WIN are two graphic tools for X Windows-Unix computers dedicated
to sequence alignment and molecular phylogenetics. SEA VIEW is a sequence alignment …

The nucleic acid sequence band now contains over 600 protein coding genes of which 107
are from prokaryotic organisms. Codon frequencies in each new prokaryotic gene are given. …

The nucleic acid sequence bank now contains 161 mRNAs, 43 new genes are added. One
sequence, that of B. mori, fibroin, is dropped due to uncertainty on the starting point for …

Frequencies for each of the 61 amino acid codes have been determined in every published
mRNA sequence of 50 or more codons. The frequencies are shown for each kind of genome …

The poor printing of our previous Figure 2 (1) is corrected. Codon usage in mRNA
sequences just published is also given. A new correspondence analysis is done, based on …

Multivariate analysis of the amino-acid compositions of 999 chromosome-encoded proteins
from Escherichia coli showed that three main factors influence the variability of amino-acid …

Previous investigations on the human genome determined: (i) the base compositions (GC
levels) and the relative amounts of its isochore families; (ii)the compositional correlations (ie, …

We compared the exon/intron organization of vertebrate genes belonging to different isochore
classes, as predicted by their GC content at third codon position. Two main features have …

Infectious diseases caused by viral agents kill millions of people every year. The improvement
of prevention and treatment of viral infections and their associated diseases remains one …

We have analyzed the correlation that exists between the GC levels of third and first or second
codon position for about 1400 human coding sequences. The linear relationship that was …
