Which is more likely to be deleterious-a 3-nucleotide deletion in the gene seque

Question

Which is more likely to be deleterious-a 3-nucleotide deletion in the gene sequence that corresponds to the active sites of an enzyme, or a 3-nucleotide deletion located somewhere else in the gene for that enzyme? Explain. As trees age, the wood at the center of the stem eventually begins to rot. How can an old tree survive with its central wood rotted? Would you expect to find heavy metal ions (i.e. a non-nutrient ion) like aluminum in the leaf Why or why not? Why are all mesophyll cells located very close to leaf veins? Which is the only level of protein folding that does not depend on bonding among R groups What did every single branch on a tree (except the main trunk) begin as?

Explanation / Answer

2. An old tree survives with the help of epicormic branches which exist as a knot on the branches providing extra support to the tree.

3. Heavy metal ions like aluminium are present on the leaf which is due to increased industrial pollution and anthrogenic pressure on the plant life.

4. palisade mesophyll cells due to change in water pressure enables opening or closing of stomata. Therefore, they lie close to the leaf as they also enable exchange of gases from leaves to the atmosphere.

5. The only level of protein folding that does not depend on bonding among R groups is the primary protein.
