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:
B
Explanation:
The lung not being not been able to exchange and remove the carbon dioxide created a health problem due to the concentration of hydrogen ions (H+) being 10X being higher than in normal body. Although the difference is just about 1, it will result increase hydrogen ion concentration 10 times, similarly an increase or decrease in pH from 4 to 2 will give rise to 100 times increase in hydrogen ion concentration. It can equally be applied to hydroxyl in concentration.

The selective breeding helps to maintain pure breed and hence exclude the hybrids.
<h3><u>Explanation:</u></h3>
Selective breeding is a very commonly practiced procedure in plant management and animal husbandry. This selective breeding helps to achieve and maintain the homozygous traits of selective characters. For example, if two dogs with white colour are breed, then their progenies will be white too. Thus the selective character i.e fur color will be maintained.
In crops, if the plants with desired fruit characteristics are bred with each other then superior quality of fruits are achieved and maintained over generations. This is very essential economically too.
You're right. The Upper Mantle is directly under the Crust. Hope this helped! =^-^=
