Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.
Answer:
d. regulatory; operator; regulatory
Explanation:
In prokaryotes, the regulation of gene expression is done at the transcription level by operons. Examples are the lac operon and the trp operon. To initiate transcription, RNA polymerase and a DNA segment are required for binding called a promoter.
DNA segments that are close to the promoter serve as binding sites for regulatory, activating or repressing proteins. They are called operons.
The Operon is a regulatory sequence close to prokaryotic DNA that lies between the structural genes and the promoter. It is responsible for controlling the transcription of structural genes. When the repressor, encoded by the regulatory gene, binds to the operator, the promoter is blocked which prevents transcription.
The Promoter is located next to an operator and is the site in the DNA molecule that binds to RNA polymerase (which is a regulatory protein) to initiate transcription.
Answer:
The part of the cell that is in charge of the synthesis of proteins are called Ribosomes.
