I need help with Biology question

OpenStudy (thesmartestderpalive):

I'm confused....

OpenStudy (anonymous):

i got this, hold on

OpenStudy (unbelievabledreams):

Same. I am filling the boxes of which statement is match. It kept saying incorrect. No more how I read the textbook, it won't tell.

OpenStudy (anonymous):

rRNA: Ribosomal RNA, a molecular component of a ribosome, the cell's essential protein factory. Strictly speaking, ribosomal RNA (rRNA) does not make proteins. It makes polypeptides (assemblies of amino acids) that go to make up proteins.

OpenStudy (anonymous):

mRna okay, do you see that box? which one of those three belongs to rRna

OpenStudy (anonymous):

what do you think? I will tell you which one is right and wrong

OpenStudy (unbelievabledreams):

The last one?

OpenStudy (anonymous):

Try the middle, im thinking that one take ;¨deliver amino acids..¨ and put it in the rRNH box

OpenStudy (anonymous):

Which one is it saying its wrong?

OpenStudy (unbelievabledreams):

I have no idea. It kept saying innocent. I read the textbook and looked for clues. Always same thing.

OpenStudy (anonymous):

Im going to look at it again hun okay?

OpenStudy (unbelievabledreams):

Thank you C:

OpenStudy (anonymous):

No problem, i had biology last year and i have my text book with me, so let me look in my book

OpenStudy (anonymous):

its alot of typing, so brace yourself girly

Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies a particular amino acid. 2. Transfer RNA (tRNA) is the key to deciphering the code words in mRNA. Each type of amino acid has its own type of tRNA, which binds it and carries it to the growing end of a polypeptide chain if the next code word on mRNA calls for it. The correct tRNA with its attached amino acid is selected at each step because each specific tRNA molecule contains a three-base sequence that can base-pair with its complementary code word in the mRNA. 3. Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis. Ribosomes are composed of a large and small subunit, each of which contains its own rRNA molecule or molecules. Translation is the whole process by which the base sequence of an mRNA is used to order and to join the amino acids in a protein. The three types of RNA participate in this essential protein-synthesizing pathway in all cells; in fact, the development of the three distinct functions of RNA was probably the molecular key to the origin of life. How each RNA carries out its specific task is discussed in this section, while the biochemical events in protein synthesis and the required protein factors are described in the final section of the chapter.

Copied it from my textbook, that information should help you. Tell me if you get more confused and i will break it down
