Introns, Exons, Intergenic space

Are introns intergenic? Properties. Intergenic regions are different from intragenic regions (or introns), which are short, non-coding regions that are found within genes, especially within the genes of eukaryotic organisms. Scientists have now artificially synthesized proteins from intergenic regions. Introns are found in the genes of most organisms and many viruses and can be located in a wide range of genes, including those that generate proteins, ribosomal RNA (rRNA) and transfer RNA (tRNA). Problems: What is a general observation about genomes? A) Bacterial genomes have more genes than mammalian genomes B) In mammalian genomes, introns are generally larger than the intergenic regions C) All transcripts derived from a genome are translated into proteins D) The number of genes in the human genome is accurately known E) Mammalian genomes contain much repetitive DNA, making sequence assembly difficult Which of the following is a major difference between RNA and DNA? A) type of sugar B) type of phosphate C) type of purines D) all of these are major differences #intergenic #intron #exon #gene #DNA #mRNA #RNA #protein #genoitype #genome
