Which of the following is the central issue underlying a problem that needs to be addressed

Imagine that you've isolated the complete human growth hormone gene directly from the human genome. After running through all th

aliina [53]

Answer:

a. Bacteria cannot carry out splicing.

Explanation:

Human genes contain non-coding sequences called introns. Transcription of genes produces primary transcripts that undergo post-transcriptional modifications to produce mature mRNA. These modifications include removal of introns, the addition of 3' poly-A tail and 5' cap. The splicing of introns from primary transcripts is followed by ligation of protein-coding sequences exons to produce mature mRNA. The mRNA leaves the nucleus and serves as a template for protein synthesis.

Splicing of introns requires specific machinery such as several small nuclear ribonucleoprotein complexes, etc. which are not present in a prokaryotic cell. Therefore, a eukaryotic gene like the gene for human growth hormone is not expressed in a bacteria cell as these prokaryotic cells cannot carry out the splicing of introns from pre-mRNA.

Their are 9 class of hazardous material:

1 CLASS 1 : Explosive

2 CLASS 2 : Gases compressed, liquefied, dissolved under pressure or deeply refrigerated.

3 CLASS 3 : inflammable liquids.

4 CLASS 4 : Inflammable solids, substances liable to spontaneous combustion substances which on contact with water emit inflammable gases.

5 CLASS 5 : Oxidising substances, organic peroxides.

6 CLASS 6 : Poisonous (toxic) and Infectious substances.

7 CLASS 7 : Radioactive substance.

8 CLASS 8 : Corrosives.

9 CLASS 9 : Miscellaneous dangerous substance.

Hazardous :A hazardous material is any item or agent (biological, chemical, radiological, and/or physical) that has the ability to cause harm to humans, animals, or the environment. This could be as a result of the material by itself or interaction with other materials.

Gene therapy is a form of

grin007 [14]

Answer:

Genetic engineering

Explanation:

Gene therapy is a form of genetic engineering used to treat genetic disorders and other diseases that can be ascribed to genetic issues.

A bad gene or malfunctioning is replace by a better gene.
This helps to address specific genetic issues.
Genetic engineering is a group term used to describe the application of recombinant DNA technology to manipulate the genotype of organisms.
Cloning, selective breeding and artificial are all forms of genetic engineering.
