Changing one base in a gene could have the
most direct effect on the
(1) function of the membrane of a cell
(2) sequence of building blocks of a protein
found in a cell
(3) number of mitochondria in a cell
(4) type of carbohydrates synthesized by a cell

2) sequence of building blocks of a protein found in a cell.

Just random FYI:

- it is a mutation, that is generally not looked upon as being severe or detrimental to the person

-by changing the base by either adding or deleting from a protein strand will cause the protein to be useless

-frameshift mutation deals with DNA sequence being shifted. For example: a DNA strand looks like a ladder. If one of the rungs on the ladders gets skipped and the next ladder rung gets the code that the previous rung should have gotten, then that is what a frameshift mutation is. Hopefully that makes sense. It's easier to explain if there was a picture.

there are other types of mutation but I won't get into them.

Hopefully this helped and good luck.

the answer is :
