Answer: Bacteria lack a mechanism for splicing out introns
Explanation:
Factor VII gene is 186k nucleotides long while the protein is 2332 amino acids long. <u>This lenght discrepancy is due to introns interrupting gene</u>, because the cell first transcribes the entire gene and then cuts introns out of the transcript. At the end, it splices the remaining pieces. Prokaryotes don't perform splicing so it can not edit out introns from the primary mRNA transcript. To produce an eukaryote gene in prokaryotes it is necessary to use a reverse transcriptase to get a cDNA sequence without the introns, and then insert that into a bacterial genome.
Answer:
A Sunlight enables this plant to make its own food. Soil Soil is a mixture of rock fragments, nutrients, air, water, and the decaying remains of living things.
Explanation:
New species often form on new islands because they evolve to fill new niches
Automatically region nervous system
Answer: and Explanation:
A.)The reason for the different products of glycogen breakdown in the two tissues is that glucose 6-phosphotase which is
a known enzyme that brings about hydrolysis of glucose 6-phosphate as a result of the creation of a phosphate group and free glucose is not available in heart and skeletal muscle, therefore,any glucose 6-phosphotase that is produced will just enters the glycolytic pathway and get converted to lactate through pyruvate, in the absence of Oxygen O2.
B) Whenever a situation involving fight or flight arises, the concentration of glycolytic precursors becomes high in order to prepare for muscular activity. Since the membrane is impermeable to any charged species, and at the same time glucose 6-phosphotase enzyme cannot be moved through the glucose transporter, then there cannot be a release of Phosphorylated intermediates from the cell. The blood glucose level must be maintained by the liver by releasing of glucose.
glucose that is later formed from glucose 6-phosphotase then enters the bloodstream.
