Theme 2: transcription; c01; dr. kajiura; 19 sept 2014. Genes in dna code for specific proteins. Central dogma: the process of copying and interpreting genes into proteins (proposed by. Francis crick: (gene expression): dna can be copied multiple times mrna translated from nucleotides amino acids which make up proteins. Dna is used as a template to generate a complementary, and anti-parallel, rna molecule. Thus, the nucleotide sequence in the dna will determine the nucleotide sequence in the rna transcript. Note: uracil replaces thymine when transcribing the template strand into mrna. Consensus sequence- nucleotide sequence that is found on dna at that site (is not exclusive to that region; can be found in different promoters with similar nucleotides) Translation and transcription can occur at the same time in prokaryotes because they lack nuclear envelope to separate the two processes. There are characteristic differences between prokaryotes and eukaryotes at the end of transcription.
