Which of the following mutations could result in a truncated protein? Choose all that apply. Which of the following mutations could result in a truncated protein? Choose all that apply. A one base pair frameshift A two base pair frameshift A nonsense mutation that changes a cysteine to a stop codon A chromosomal-level insertion A missense mutation that changes a phenylalanine to a leucine A chromosomal-level deletion An in-frame removal of three base pairs

A truncated protein refers to a protein that gets shortened due to a mutation, which does not allow the process of translation to take place properly. The formation of a truncated protein can take place due to a frameshift mutation of one or two base pairs. In such kind of mutation, a single or two base pairs get withdrawn from the sequence resulting in the formation of a completely changed triplicate codon sequence, which may result in the generation of a truncated protein comprising a different set of amino acids.  

A nonsense mutation can also result in the formation of a truncated protein. A nonsense mutation generally codes for certain kinds of amino acid, however, post mutation can get converted into a stop codon. This transformation can result in the formation of a truncated protein.  

Deletion or insertion at the chromosomal level can also result in the formation of a truncated protein. As insertion and deletion of a certain concentration of DNA can probably lead to the formation of a novel codon that can either be a nonsense codon or a stop codon, which may eventually result in the formation of a truncated protein.  

Hence, the correct answers are statements 1st, 2nd, 3rd, 4th, and 6th  

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
