What is the function of the trpR terminator? Operon: Operon may be defined as a group of adjacent genes that function in a harmonized manner as a genetic unit. Its components, namely, a promoter, an operator and a structural gene are involved in the transcription process as one unit. ...
An operon is a set of genes that are regulated together and controlled by a single promoter. This unit of genetic material consists of a promoter, operator, and structural gene(s) that are transcribed into mRNA together. Operons are commonly found in prokaryotic organisms (e.g., bacteria) ...
What would happen if there was a mutation in the operator of the trp operon? Briefly explain the process of DNA replication. How does DNA replication initiate? How are primers involved in the replication of DNA? Explain fully how DNA is replicated. ...
粒子群算法是一种优化算法，通过模拟粒子在搜索空间中的移动来寻找最优解。___is an optimization algorithm that searches for the optimal solution by simulating the movement of particles in the search space.
Finally, I describe a simple procedure for introducing any DNA fragment in place of the lac operator site on the E. coli chromosome.doi:10.1016/0022-2836(88)90601-8DreyfusMarcElsevier LtdJournal of Molecular BiologyDreyfus M (1988) What constitutes the signal for the initiation of protein ...
Another example of a cis gene is the operator gene in lac operon. It when bound by the repressor molecule is unable to initiate transcription. However, when the inducer (lactose) binds to the repressor molecule inactivating it, normal transcription can occur. Share Possibly...
The Lac repressor, by contrast, binds to specific operator sites on DNA, introduces lesser distortions in the double helix [6], and interconverts between the tightly closed, V-shaped protein architecture observed in the crystalline state and an extended open form with widely separated DNA-...
