Explanation:
A molecular clock determines evolutionary relatedness by examining how many mutations or random changes in DNA, there are between two organisms. When we map the relatedness of different organisms, we are creating a phylogenetic tree. At some point, all organisms that are alive today shared a common ancestor.
excretory system: removes waste from blood.
respiratory system: obtains oxygen so the energy in the nutrients can be extracted.
circulatory system: transports nutrients from small intestine to the othet tissues.
nervous system: regulates and controls digestive functioning.
( Am not completly sure, but i think this is the answer)
A. There are 4 codons
Idk B
The structural variations that can happen in a protein after translation to make it function appropriately are:
• Folding – In the cytoplasm it partakes chaperonin protein that will aid to fold the protein into a purposeful shape. The hydrogen bonds will form to create secondary protein and disulfide bonds will form tertiary structure and hydrogen bonds.
• Cleavage – The activation into a purposeful protein over cleavage of certain amino acid sequences in which the amino acid order can fold to form the secondary or tertiary structure.
• Chemical Modification – A method of chemically responding a protein or nucleic acid with chemical components.
• Elaboration – In particulars of folding, chaperones, kinds of bonds, the role of Golgi, combination into current molecular arrays. Etc.
