Answer:
1. Iron (ferrous)
2. Zinc
Explanation:
Iron is a major component of hemoglobin which is responsible for the transportation of oxygen from lungs to all cells of the body, while excess iron has also negative effects on our body such as it causes liver disease (cirrhosis, cancer), heart attack, diabetes and sometimes it causes death. Zinc also plays a vital role in our body because it is a main component of all cells and also provide protection against microbes. It also needed for the production of DNA and protein. Zinc in excess amount causes copper deficiency, Nausea Stomach Pain and Diarrhea.
Answer:
The appropriate order for the basic steps of protein synthesis are listed below
Explanation:
First step D The large ribosomal subunit joins the initiation complex preparing it for elongation stage.
Second step C Binding of mRNA by small Sub unit followed by association of a particular initiator aminoacyl tRNA that recognizes the first codon.
Third step B The P site is occupied by peptidyl tRNA carrying the growing polypeptide chain.
Fourth step A The elongation reaction transfers the peptide chain from the peptidyl tRNA in the p site to the aminoacyl tRNA in the A site.
Fifth step E The new longer Peptidyl tRNA moves from A site into the p site as the ribosome moves one codon further along the mRNA.
