Question

How can a cell make many different kinds of proteins out of only 20 amino acids? Of the myriad possibilities, how does the cell 'know' which proteins to make?

Accepted Answer

Hello everyone and welcome to today's video. So today we have the which of the following answer choices is responsible for the amino acid sequences of the prolactin hormone. And since it's made up of amino assets, this is going to be a protein. So what is responsible for the amino acid sequences of protein? Well, let's go back to what we call in biology. The central Dogma. Remember that everything starts with D. N. A. Or with genes. These genes are going to be transcribed into RNA. And this RNA is going to be translated into proteins which is what we have here. This prolactin hormone, it's a protein. So remember that the sequence of these genes is going to determine the sequence of amino assets and the sequence of amino assets is going to determine the protein. But eventually the primary determinant on what the protein is going to be is going to be the genes that transcribe or translate into these protein. So as a result, the correct answer choice for this question is going to be the sequence of the prolactin gene, nuclear types. So whatever order these genes have are going to determine the order of the amino acid sequence once they are eventually translated. That is the final answer to her question. And I really hope this video helped you
