Answer:
DNA vaccines consist of DNA vectors or plasmids (small double-stranded DNA rings originally derived from bacteria, but unable to cause infection) into which the genes encoding one or more immunizing proteins of the infectious agent have been inserted causing the disease to be prevented.
Explanation:
Vectors are the functional unit of naked DNA vaccines. Genes that encode the proteins of interest and are of bacterial origin are inserted into these vectors. Bacterial plasmids are circular DNA molecules that self-replicate extrachromosomally in bacteria. The genes encoded in these plasmids are under the control of promoters, almost always of viral origin. When a plasmid is introduced into the cell it translocates to the nucleus, where transcription of the transgene begins; the transcripts are then taken to the cytoplasm and translated there. The newly synthesized proteins are degraded in the proteasome to 8-10 amino acid peptides, which are transported to the endoplasmic reticulum. Peptides of high affinity with their respective MHC I molecule stabilize and enter the secretory pathway, thus reaching the cell surface, where they are coupled with the T-lymphocyte receptor (TcR) present on the surface of T lymphocytes cytotoxic drugs (CD8 +) to induce their activation.
Answer:
when the man and the woman really produce the baby from a woman that haves the baby.
Explanation:
Answer:
The circle of life, in which energy flows into the world from the sun, giving plants that energy to live. All of the organisms in an ecosystem are chemical machines driven by the energy captured in photosynthesis. The organisms that first capture energy, the producers, include plants, some kinds of bacteria, and algae. All other organisms in an ecosystem are consumers.
The plants energy will then be transferred to a small animal, most likely a rabbit or maybe a mouse; depending on the plant. The small animal will then be eaten by a bigger more dominating animal like an eagle or a snake. It just goes on and on. The eagle or the snake will get eaten by a bigger animal or will decompose into the earth giving the soil and plants around it that same energy.
