Answer:
The sugar, is used inside cells to modify proteins, turning the proteins off or on, helping or preventing their interactions with other proteins, keeping them from destruction or allowing their destruction.
Explanation:
It’s the last one.
All of these are parts of the cell theory.
The photic zone would support the greates variety of coral reef ecosystem.
Explanation:
- Photic zone of the marine environment is that region where the light penetrates.
- This zone supports a large number of phytoplanktons, zooplanktons and many fishes.
- Coral reefs are ecosystem that are formed by corals that live is symbiosis with dinoflagellate algae.
- To support the growth of a great variety of coral reef a region would need ample amount of light.
- Hence, the photic zone would support the greatest variety of coral reef ecosystem
Answer:
D. They block communication between enhancers and non-targeted promoters
Explanation:
Insulator sequences are the group of DNA sequences that protect the protein-coding regions of the DNA from the surrounding regulatory sequences. Some insulator sequences are present between the enhancers and promoters of a gene. These insulator sequences do now allow these enhancers to regulate the expression of genes by sending inappropriate signals.
However, if the insulator sequences are not present between the enhancers and promoters of certain genes but are located somewhere else, enhancers can upregulate the expression of these genes.
HIV can be treated via gene therapy by inducing mutations that restore the normal genome sequence.
<h3>
What is gene therapy?</h3>
Gene therapy is a revolutionary technique used in molecular biology to restore the expression of defective genes that suffered mutations.
Gene therapy involves modifying the nucleotide (DNA) sequence in order to correct the production of defective proteins associated with disease states.
Moreover, mutations due to HIV are a consequence of the insertion of this retrovirus in the host genome.
In conclusion, gene therapy is able to treat HIV by inserting gene regions that restore the normal nucleotide sequence.
