Answer:
<h2>
Tetracycline affects the binding of tRNA to the ribosome.
</h2><h2>
Chloraamphenicol affect: growth of the protein chain.</h2>
Explanation:
1. Antibiotics block protein synthesis mostly in prokaryotes only as prokaryotes contain 70s ribosome.
2. Antibiotics are of various types, which have different targets in protein synthesis, some works on small sub-unit of ribosome and some on large sub-unit.
⇒Tetracycline would directly affect binding of tRNA to the A site on ribosome. tRNA brings amino acid to the ribosome which pairs with codon on mRNA.
⇒ Chloraamphenicol would directly affect growth of the protein chain because it block peptidyl transfer so the elongation of protein terminates.
It is theorized that all life begun by microorganisms being able to take advantage of underwater volcanic vents. Furthermore, it is theorized that all life (except plant life) came from the ocean. Variety in earth has come about from variation, where different species have different characteristics for their survival. Also note that gravity has led to the development differences between earth creatures and ocean creatures. Ocean creatures have more mass than land. Usually this is because of the pull of gravity.
