Answer:
Yes, grasshopper is a threat to the crops because it is a herbivores.
Explanation:
Grasshopper is an insect which feed on plants so that's why it is called herbivores. It is also known as primary consumer in the trophic levels because they feed on producers. Grasshoppers destroy field crops which means that it is a pest. So for controlling pest, the farmer uses pesticides which kills only grasshoppers and the crop is not affected by the pesticides.
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.
Because as trials go on scientists discover more information and alter the theories and that is why they are referred to as a "theory" instead of a scientific "law"
Answer: The binomial naming device is the device used to call species. Each species is given a call that includes parts. The first component is the Genus to which the species belongs, and the second component is the species call.
1) The cell membrane surrounds the cytoplasm and prevents it from spreading out of the cell
2) Albumin which is a protein transport free fatty acids, which result from lipid digestion, in the blood stream by binding to it
3) The nucleus contains the chromosomes which carry the DNA on them
