Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the letters G, U, A, and C to denote the nitrogenous bases guanine, uracil, adenine, and cytosine) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.

Some RNA molecules play an active role within cells by catalyzing biological reactions, controlling gene expression, or sensing and communicating responses to cellular signals. One of these active processes is protein synthesis, a universal function where RNA molecules direct the assembly of proteins on ribosomes. This process uses transfer RNA (tRNA) molecules to deliver amino acids to the ribosome, where ribosomal RNA (rRNA) then links amino acids together to form proteins.

Like DNA, most biologically active RNAs, including mRNA, tRNA, rRNA, snRNAs, and other non-coding RNAs, contain self-complementary sequences that allow parts of the RNA to fold and pair with itself to form double helices. Analysis of these RNAs has revealed that they are highly structured. Unlike DNA, their structures do not consist of long double helices, but rather collections of short helices packed together into structures akin to proteins. In this fashion, RNAs can achieve chemical catalysis (like enzymes). For instance, determination of the structure of the ribosomean enzyme that catalyzes peptide bond formationrevealed that its active site is composed entirely of RNA.

New Jersey Gov. Chris Christie vetoed a bill Friday that would have banned crates that severely limit the mobility of pregnant pigs, a move that will win favor with Iowa farmers and spark more speculation about Christie's presidential aspirations but cause outrage among animal rights activists who pushed for the ban.

Critics consider the small metal crates a form of animal cruelty -- the pigs aren't able to turn around in the limited space -- but advocates say they prevent sows from accidentally lying down or stepping on piglets.

Despite its strong bipartisan support in the state legislature, the Republican governor vetoed a version of the bill in 2013. When a nearly identical version passed again in the Democratic-led legislature, Christie faced mounting pressure this fall from activists and celebrities, including Bill Maher, Danny DeVito, Martha Stewart and Edie Falco.

Jon Stewart gave the issue wider attention when he featured it in a segment on Comedy Central's "The Daily Show" this month. And Matthew Scully, a former speechwriter and adviser to President George W. Bush, wrote a lengthy essay for National Review Online, spelling out a case for banning the crates.

In a statement, Christie said the bill is a "solution in search of a problem" and a "political movement masquerading as substantive policy." Arguing that it's not a practice in New Jersey, Christie said it should be left to the state's Board of Agriculture, which currently doesn't outlaw the crates.

The move, announced by his office the day after Thanksgiving, places 2016 squarely in the spotlight. With more than 20 million pigs, Iowa is the nation's largest pork producer, and the state's governor, Terry Branstad, told The Associated Press that he urged Christie to veto the bill when a similar version came to the New Jersey governor's desk last year.

(CNN) -- Baseball's biggest stars are in New York for Tuesday's All-Star game, as the sport says goodbye to one of its most famous landmarks.

Joseph Cornacchia, left, used to play with Babe Ruth when he was a kid, his son Jim says.

It's the Yankees' final season at the "House that Ruth Built," and MLB.com reports that 40 Hall of Famers are expected to attend the historic event.

We asked CNN.com readers to share their baseball memories and to tell us about meeting their favorite players.

iReporter Jim Cornacchia of Rye, New York, says his grandmother taught Babe Ruth to "make a mean batch of chili."

He said the legendary slugger would come to Greenwood Lake, New York, during the off season and would visit with his family. iReport.com: Ever met your favorite player?

Cornacchia's father, Joseph, who just turned 76, would play wintertime games with "The Babe" as a child, and even built a snowman with him.

Patrick Palmer, 43, has been a Yankees fan since he was a kid, even though he grew up in Iowa.

"My father was a Yankees fan, and it was just handed down through the generations," he said.

Palmer has a baseball signed by about 20 Yankees players and other memorabilia, but said his biggest thrill was meeting relief pitchers Sparky Lyle and Rich "Goose" Gossage.

"It was also amazing to shake hands with one of the most feared pitchers of his day, Goose Gossage, and really see what a gentle person he could be," See what Palmer wrote on iReport.com.
