Answer:
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.
The correct answer is: b. the removal of introns and alternative splicing of exons
Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail, RNA editing.
RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).
Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.
You can reduce the risks of radiation exposure by:
1. Eating foods that contain chlorophyll. Foods that contain this substance detoxify the blood, helping to remove all kinds of nasty toxins including radiation.
2. Ingest sea vegetables. Kelp, dulse, and agar contain natural iodine, which protects against radioactive iodine found in foods like dairy products.
3. Supplement with bee pollen. It can protect your body against x-ray induced radiation sickness.
4. Limit daily exposure to nonionizing radiation.
