15. Which of the processes has more than one type of RNA involved?
erastova [34]

Answer:

Translation

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

People with diseases that result in the malabsorption of which nutrient are at risk for a vitamin d deficiency?
grigory [225]

Inadequate dietary vitamin D or its deficiency leads to malabsorption of calcium. Nutritional disorder leads to the rare disease rickets, which causes bones to become soft and bend in children. In adults, vitamin D deficiency leads to osteomalacia, which causes weak bones, bone pain and muscle weakness.

The body needs vitamin D to properly absorb calcium and phosphorus from the diet. However, keeping the right quantities of calcium and phosphorus in bones is challenging when vitamin D levels are low.

The two sources of vitamin D are-

  • Natural sunlight
  • Foods such as fish oil, Egg yolk and fatty fishes like salmon and mackerel

There are other disease conditions which lead to poor absorption of vitamin D-

  • Inflammatory bowel disease
  • Celiac diseases
  • Kidney problems
