19. FALSE. DNA polymerase (an enzyme) catalyzes the formation of new DNA strand, not "makes".
20. All of the Adenine (A) in DNA strand is transcribed into U (Uracil) in mRNA. So the answer should be AGGAUCUGA. (Notes : T,G,C are transcribed same as the complementary of the DNA strand. Only A is transcribed to U.
21. AUG in a mRNA encodes for start codon for translation of a protein, so the answer should be either the second 1 or the forth 1. I don't have the table to determine the amino acids encoded by triplets (codons in mRNA) now. So, check it yourself.
22. The stop codons are either UAA, UGA, or UAG. TGC at the end will be transcribed in to ACG, so it's not a stop codon. Answer is either 3rd or 4th.
23. mRNA (m is for messenger, remember?)
24. tRNA (t is for transfer, remember?)
25. rRNA (r is for ribosomal RNA, it's a part of the ribosomes that involve in translation.
Genetics are really quite easy. Don't give up, don't study for your parents and teachers, study and learn for yourself!
All the best for you....

A few more questions? Dude, that's your entire homework. You do know this is cheating, right? What happens when you have a test? Post it online and have us do it for you?
Here are some great biology notes from a student posted online, written in basically, high school English. Read them. Learn them. You will pass with flying colors.

Maybe you and tanbella could share a biology book or something.

SORRY I CANT HELP I HATE BIOLOGY I HAVE A TEST TOMMOROW AND I HAVE NO CLUE WUT IT IS ABOUT...AHH..BIOLOGY SUCKS...LOL..
BY THEY WAY I DONT KNOW IF U HAVE THE SAME BOOK AS ME BUT MINE HAS LIKE AN OWL ON IT
