In 1990, scientists at the National Institutes of Health used gene therapy to try to treat a 4-year-old girl suffering from seve

re combined immunodeficiency disease (SCID). This genetic disease made her extremely susceptible to infections. The scientists used a virus to inject normal genes into the girl's immune system cells. The experiment was moderately successful, and the girl's health improved but only for short periods of time. If this form of gene therapy could be fine-tuned, how would it impact society? A. People would need to be genetically tested before having children together. B. Many genetic diseases would be curable. C. The number of infections from genetically-engineered viruses would increase. D. Most Americans would no longer suffer from heart disease.

<u>Answer:</u>

<em>B. Many genetic diseases would be curable. </em>

<u>Explanation:</u>

Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein. On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.  

A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.

What is the new peptide chain when the new dna segment is translated for 3'- TACAGGGTGCTACCCACT-5'
kakasveta [241]

Answer:

Methionine- Serine- Histidine- Aspartate- Glycine- stop

Explanation:

Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.

In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the

mRNA sequence from this DNA during transcription will be:

AUG UCC CAC GAU GGG UGA

From this mRNA sequence, the peptide chain that will result following translation is:

Methionine- Serine- Histidine- Aspartate- Glycine- stop

a race car driver drives one lap around a track that is 500 meters in length. what is the drivers displacement at the end of the
sleet_krkn [62]

Answer:

0 meters

Explanation:

When we talk about displacement, think that the think of it as the measure of the distance between the starting point of the object, from its end point.

Since we are talking about a lap around a track, it would mean that the starting point is also the end point. So if you started and end at the same point, the distance between it would be 0.

Classify each statement based on whether it describes prokaryotes only, eukaryotes only, or can describe both prokaryotes and eu
Phantasy [73]

Answer:

unicellular - both prokaryotes and eukaryotes

contain mitochondrion - eukaryotes only

are generally less than 2 pm - Prokaryotes only

multicellular - eukaryotes only

lack membrane-bound organelles - prokaryotes only

Explanation:

Prokaryotes are generally unicellular, that is, they are made up of single cells only. However, there are unicellular and multicellular eukaryotes with some eukaryotes like humans and advanced plants having as many as millions of cells.

Prokaryotes generally lack nucleus and other membrane-bound organelles such as chloroplast and mitochondrion. Eukaryotes on the other hand have nucleus and membrane-bound organelles such as mitochondrion and chloroplast.

When it comes to size, prokaryotes are generally small and microscopic while eukaryotes consist of both microscopic and macroscopic cells or organisms. However, prokaryotes are generally smaller than microscopic eukaryotes.
