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:
most forms of cancer are caused by somatic mutations
Explanation:
BB and Bb would be blue because they are both dominant and bb would be green because it is recessive
The correct answer is false and here is why:
Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.
Controlled burns have a completely different affect. They burn the under brush to help keep the soil rich with nutrients, plus they also help to prevent large crown fires that burn down whole forests from happening.
Clear cutting is a bad thing and controlled burns are a good limiter for a forest.
