Which of these statements about amino acids is entirely true? there are four main types.
00:06
There are the biomolecules that acidify the cell to allow themselves to be broken down and recycled by the body.
00:12
They make up the double helix of dna, or they are typically found in cytoplasm, where ribosomes incorporate them into protein chains.
00:19
Okay, so the correct answer for this one is d.
00:23
Let's go through these answers.
00:25
First of all, a, there aren't four main types, there are 20.
00:29
There are 20 varieties of amino acid that we use to make our proteins.
00:33
There are four nucleotides, which is likely what this is talking about, because if we look at c, again, the double helix of dna is made up of nucleotides, which are adenine, thymine, cytosin, and guam.
00:46
Amino acids are the building blocks of proteins.
00:50
Okay, as for b, acidifying the cell to allow the cells to be broken down and recycled by the body.
00:57
So if a cell has to be taken care of, this is a process called apoptosis...
