Answer:Chlorophyll breaks down.
Explanation: In fall, there are changes in the daylight and temperature. This causes the leaves to stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall color.
The complete phenotype of an organism is dependent on : genotype , penetrance , expressivity and polygenes
Answer:
- Bacteria cannot remove intronic sequence from a gene, so if the gene for factor VIII were transcribed, it would translate to a nonfunctional protein.
- The bacteria will not recognize the eukaryotic promoter to transcribe the gene.
Genome engineering steps:
I. Isolate by PCR the mature mRNA of the target factor VIII gene
II. Synthesize a complementary DNA (cDNA) for this mRNA by using a reverse transcriptase enzyme
III. Insertion of the cDNA into a plasmid vector
IV. Expression of the protein in the host bacterial cell through transformation
Explanation:
Bacteria lack the spliceosome (ie., the eukaryotic machinery required to remove introns from the primary mRNA), because bacterial genes do not have introns. Moreover, eukaryotic organisms require several proteins that bind to the promoter sequence and subsequently recruit the RNA polymerase to initiate this process. In bacteria, transcription is controlled by proteins that bind to cis-acting sequences which regulate the transcription of adjacent genes. In contrast to bacteria, eukaryotic genes have many classes of promoter and enhancer elements.
Genome engineering technologies can be used to produce bacteria expressing human proteins derived from synthetically introduced human genes (see steps above). For example, recombinant bacteria expressing the human insulin gene have already been designed by using E. coli as cell factories.
Answer: The energy comes from the sun.
Explanation:
Most of the people with sicken multiple sclerosis have experienced vision difficulties. A vision problem is often one of the first symptoms of relapsing multiple sclerosis. It is a disease of the central nervous system which includes the optic nerve. Optic nerve transmits light and visual images to the brain. An inflammation of the optic nerve may cause a sudden loss of vision.
