It seems that you have missed the necessary options for us to answer this question, but anyway, here is the answer. The statue of Leshan giant Buddha in Sichuan, China, is carved directly into the mountainside, and the <span>color and texture of the statue are constantly changing due to the pollutants from vehicles and industries nearby. The two main causes of the changes to the statue are RAINFALL AND CHEMICAL REACTION.</span>
They both Break down characteristics of organisms, this is a general statement, it can apply to anything as well
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.
<span>Vitamin D.
Vitamin D is made from 7-dehydrocholesterol and needs UV light in order to be activated. Because the children are not exposed to sunlight, they are receiving insufficient UV light.</span>
