Codon distributions in DNA.
The codons, 64 in number, are distributed over the coding parts of DNA sequences. The distribution function is the plot of frequency versus rank of the codons. These distributions are characterized by parameters that are almost universal, i.e., gene independent. There is but a small part that depends on the gene. We present the theory to calculate the universal (gene-independent) part. The part...
متن کاملAntitumor Response to a Codon-Optimized HPV-16 E7/HSP70 Fusion Antigen DNA Vaccine
Background: Vaccines based on virus-like particles are effective against Human Papilloma Virus (HPV) infection; however, they have not shown a therapeutic effect against HPV-associated diseases. New immunotherapy strategies based on immune responses against tumor antigens can positively affect the clearance of HPV-associated lesions. Objective: To generate two therapeutic fusion DNA vaccines (o...
متن کاملDNA mismatch repair and synonymous codon evolution in mammals.
It has been suggested that the differences in synonymous codon use between mammalian genes within a genome are due to differences in the efficiency of DNA mismatch repair. This hypothesis was tested by developing a model of mismatch repair, which was used to predict the expected relationship between the rate of substitution and G+C content at silent sites. It was found that the silent-substitut...
متن کاملDNA G+C content of the third codon position and codon usage biases of human genes.
The human genome, as in other eukaryotes, has a wide heterogeneity in the DNA base composition. The evolutionary basis for this heterogeneity has been unknown. A previous study of the human genome (846 genes analyzed) has shown that, in the major range of the G+C content in the third codon position (0.25-0.75), biases from the Parity Rule 2 (PR2) among the synonymous codons of the four-codon am...
متن کاملDuplication count distributions in DNA sequences.
We study quantitative features of complex repetitive DNA in several genomes by studying sequences that are sufficiently long that they are unlikely to have repeated by chance. For each genome we study, we determine the number of identical copies, the "duplication count," of each sequence of length 40, that is of each "40-mer." We say a 40-mer is "repeated" if its duplication count is at least 2...
