27u4 transcription is the synthesis of mrna copied from the dna base sequences by rna polymerase define transcription outline the process of transcription including the role of rna polymerase and complementary base pairing identify the sense and antisense strands of dna given a diagram of translation. Start studying biology dna replication transcription translation learn vocabulary terms and more with flashcards games and other study tools the two steps of gene expression are transcription and translation mistakes to the dna sequence during replication transcription or translation are called mutations you might also . Transcription copies the dna into rna while replication makes another copy of dna both processes involve the generation of a new molecule of nucleic acids either dna or rna however the function of each process is very different with one involved in gene expression and the other involved in cell division. They will explore how mutations genetic or epigenetic lifestyle chemicals radiation viruses resulting in cancer the student will connect changes that occur in the genetic code during transcription and translation to the deleterious impact on proto oncogenes that promote cell division and tumor suppressor genes that normally inhibit it. Dna replication transcription and translation biology essay chapter 5 this chapter briefly outlines the concept of dna replication and intends to make the reader understand how dna replicates itself the details of transcription of dna into rna will also be explained lastly translation of rna into proteins will be elaborated
