And it turns out these sites are also important for the regulation of RNA transcription termination. They are often found in the vicinity of highly transcribed regions, including tRNA genes. Researchers have also uncovered an association between replication fork pause sites and genetic recombination.As...
Explain the regulation of gene expression in eukaryotic cells. What are the types of transcription activators in eukaryotes? Which of the following is characteristic of genes and gene regulation in bacteria, but not in eukaryotes? a) presence of enhancers b) capping of mRNAs c) many chrom...
Metagenomic studies have shown that antibiotic resistance genes are ubiquitous in the environment, which has led to the suggestion that there is a high risk that these genes will spread to bacteria that cause human infections. If this is true, estimating the real risk of dissemination of resistanc...
