The lac operon consists of regulatory regions such as the promoter as well as the structural genes lacZ, lacY, and lacA, which code for proteins involved in lactose metabolism. What would be the outcome of a mutation in one of the structural genes of the lac operon?

You have discovered a very small amount of DNA from an ancient organism that you want to save and study. What is the very first thing you should do to allow you to study this DNA in the lab?

Examine the table of codons in the table. What amino acid sequence will be produced based on the following mRNA codon sequence?5′-AUG-UCU-UCG-UUA-UCC-UUG-3′

Please use the following information to answer the question(s) below.A part of an mRNA molecule with the following sequence is being read by a ribosome: 5′-CCG-ACG-3′ (mRNA). The charged transfer RNA molecules shown in the table (with their anticodons shown in the 3′ to 5′ direction) are available. Two of them can correctly match the mRNA so that a dipeptide can form.The anticodon loop of the first tRNA that will complement this mRNA is
