Web14. Consider the lac operon. What happens if lactose levels are low? Put the following list in order of when they occur (1-6) starting with low levels of lactose.. 4 Lactose from the environment enters the cell and binds to LacI, which leads to a conformational change in LacI. 3 When RNA polymerase tries to bind to the promoter, it cannot get past the LacI … WebApr 7, 2024 · RT-PCR Sanger sequence results. (A) The LAMA2 c.5562+5G>C variant results in the insertion of 11 nucleotides of intron 38 within the transcript, generating a premature stop codon (p.Tyr1855Leufs*5) in the patient but not her mother.

There are different types of genetic mutations that can occur in a cell. Point mutations involve the replacement of one base with another.Frame-shift mutations occur when a base is added or removed from the sequence. Non-sense mutations create a stop codon, which can prevent the protein from being produced entirely, while ... inam martial art academy gym
