operon is made up of the promoter‚ structural genes and the operator. Transcription depends on the regulator‚ it may be located anywhere on the bacterial chromosome. The regulator codes for the repressor‚ which binds to the operator. When the repressor is bound to the operator‚ it blocks the promoter. Therefore the RNA polymerase either can’t bind to the DNA molecule or it can’t begin its movement along the molecule. No transcription can occur. The repressor depends on the effector‚ which allows it to

Chapter 10 and 11– Homework 1. Describe the stages of transcription. Initiation- Initiator tRNA binds to small ribosomal subunit. Small subunit/tRNA complex attaches to mRNA and moves along it to an AUG “start” codon. Large ribosomal subunit joins complex. Initiation must occur in the order listed above. Elongation- mRNA passes through ribosomal subunits. tRNAs deliver amino acids to the ribosomal binding site in the order specified by the mRNA. Peptide bonds form between the amino acids and

chromosomes. Eukaryotic cells have information processing organelles‚ such as the nucleus which houses most of the cell’s DNA‚ and ribosomes which use information from DNA to produce proteins. In prokaryotes gene regulation begins during transcription. Transcription begins when RNA polymerase binds to the promoter. RNA polymerase then begins to separate the two DNA strands and initiates copying. Once this has occurred‚ a terminator sequence signals the end of the gene. The terminator sequence gets

range from insertions‚ deletions‚ nonsense‚ and even repeats‚ which ultimately can result in a nonfunctional protein. The APC gene produces a protein known as the APC protein that is involved in regulating cell adhesion‚ signal transductions‚ and transcription activation. Park and Vogelstein (2003) stated that‚ “the localization of the APC protein is in the basolateral membrane of the colonic epithelial cells…” When mutations occur within this specific gene‚ it causes excessive proliferation of the colonic
