Keep a finger on the pulse of science by keeping up with some of the latest science discoveries and inventions.  Times they are a changing - and science is the engine of that change.

Science News pages contain a great deal of information about RNA and its role in cell biology for classroom and homeschool teachers, parents, and students of all ages.  This page is designed to serve as a hub in all of the information to direct you to your area of specific interest.

Ribonucleic Acid (RNA) plays a pivotal role in 'one gene - one protein' theorem central to biology.  Messenger RNA (mRNA) is synthesized as a sort of portable version of the gene encoded in the DNA.  In eukaryotic cells it travels from the nucleus, where the DNA is located, into the cytoplasm, where the ribosomes or protein-making machinery is located.  In both eukaryotes and prokaryotes mRNA is the gene copy used by the ribosomes in the synthesis of the protein itself.

A second form of ribonucleic acid is also pivotal in protein synthesis and that is transfer RNA (tRNA).  There is one tRNA for each of the triplet codons that are the 'codes' for translating a string of nucleotides into the string of amino acids.  tRNAs are synthesized as copies of specific areas of the DNA.  Once in the cytoplasm, enzymes hook specific amino acids to the proper tRNAs.  These 'charged tRNAs' then attach to the mRNA/ribosome complex in the protein synthesizing process.

Check out the questions that students, parents, teachers and life-long learners have sent into Dr. Pat regarding RNA and the answers.  You'll find things like: DNA can be compared to a book in a library.  This book is full of instructions on how to make all sorts of useful things.  mRNA can be compared to a copy of one page of the DNA book that tells you how to make a great 'whatizit'.  The mRNA copy is then taken from the library to the workshop where the instructions are faithfully followed to produce the 'whatizit'.

These pages are constantly being updated with the latest breakthroughs and discoveries in biology, medicine, archaeology, astronomy, marine biology or about endangered species or our planet earth.  This can be useful information for term papers, lesson plans, or to simply keep up on the fascinating world around us.
