The concepts will be taught in depth during essential question 3. UniGene is a NCBI database of the transcriptome and thus, despite the name, not primarily a database for genes.Each entry is a set of transcripts that appear to stem from the same transcription locus (i.e. This video discusses the concept of duplicate gene interaction. Thus, phenotype is the result of the interaction between genotype and environment. This happened after it was found that genes were not single units but a long continuum and there was the concept of alternative splicing and trans-splicing. Muhammad Riaz (A026) ♦ Length from several bps to several kbs. William Beteson in 1905 coine the term genetics, 4. If you or someone you love has been diagnosed with a genetic condition, you may be finding it difficult to keep up with all of these genetics-based terms.
