WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. WebJan 13, 2024 · Missense. Mistake in the DNA code, one of the DNA base pairs is changed. Nonsense. Single change in DNA code produces stop codon, prematurely terminates protein synthesis. Insertion. Addition of one (or more) nucleotide base pairs into the DNA sequence. Deletion. A piece of DNA is removed from the sequence. Frameshift. Webreading frame. The sequence of nucleotide triplets (codons) that runs from a specific translation start codon in a mRNA to a stop codon. Some mRNAs can be translated into different polypeptide s by reading in two different reading frame s. (Figure 4-21) chiltons repair manual online
