Some genes only go through transcription (in nucleus) but never translation (in cytoplasm) Transcription factors: proteins involved in the process of converting, or transcribing, dna into rna. Rna polymerase is reading one of the 2 strands depending on the direction. Non-coding rna genes trna, rrna (ribosomal rna: never translated into protein), mirna. Transposons a dna sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell"s genome size. creating or reversing mutations and altering the cell"s genome size. 1 can stay doing the old function; the other can evolve. Reverse genetic: start with gene, and identify phenotype. Create 2 identical cells from 1 mother cell. Create 4 genetically unique haploid cells from mother cell. Parental gametes: same thing they get from their parents (not crossing over occurs) vs recombinant gametes: crossing over occurs. Draw out phases of cell division with or without crossing over**
