Number of RNA transcripts: 60,000 in yeast according to B10NUMB3R5 website tens of thousands according to From DNA to RNA- Molecular Biology of the Cell document 43,000 according to What transcripts are found in a human cell? - Genome Biology

Copy number of less abundant transcripts: 1-5 according to What transcripts are found in a human cell? - Genome Biology almost one-quarter of expressed protein-coding genes and 80% of the detected lncRNAs are present in our samples in 1 or fewer copies per cell. according to Landscape of transcription in human cells Copy number of more abundant transcripts: highest number: 9,417 according to What transcripts are found in a human cell? - Genome Biology highest number around 50,000 according to "Mapping and quantifying mammalian transcriptomes by RNA-Seq." search for transcript abundance info 3-29-13
