I believe the answer for the above question is that it cannot bind to the inducer. An inducer molecules regulates gene expression, it can bind to protein repressors or activators. The binding of the inducer to the repressor prevents the repressor from binding to the operator. A super repressor is a repressor that binds to an operator and is non-iducible so it can not be removed. These are dominant because they will bind and never be removed, even if the wild type is attached to one, once it is removed the lac IS may attach and never be removed.
1 billion years for oxygen to become a large component of Earths atmosphere
Answer:
here is the ans
Explanation:
Proteins destined for secretion or incorporation into the ER, Golgi apparatus, lysosomes, or plasma membrane are initially targeted to the ER. In mammalian cells, most proteins are transferred into the ER while they are being translated on membrane-bound ribosomes .
Ihope this helped you
Similarities: both have cell membranes, DNA, cytoplasm
Differences: only eukaryotic cells have mitochondria/chloroplasts, nuclear membrane, endoplasmic reticulum, DNA in a chromosome
Answer:
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. Most organisms decompose before this can happen.
