Put your pinkies in the air!

I want to do the Alpha Kappa Alphas of Tumblr rollcall. Gotta meet and follow more sorors.

Rep your chapter and region! Or just reblog so we can create our own little Tumblr community.

Bringing this back…

Hey Pham…!

Hey, PHam!! Y’all can rep your chapters/regions, too. #ThirstPham lmaaaaoooo

you ain’t got to tell my black and gold self twice. Fall 2012 initiate of THee (Raw) Tau Eta Chapter of Alpha Phi Alpha Fraternity Inc. seated at The College of Charleston, Charleston SC under the umbrella of the Southern Region

In the process of transcription, an enzyme called RNA polymerase painstakingly copies a strand of DNA, and sends the freshly copied messenger out into the world, ready to tell ribosomes how to synthesise proteins.

Before we get onto how this is done, let’s take a look at what ribosomes are. The ribosome is a protein-making machine that’s actually made of RNA. It has two parts or subunits that bind on either side of the incoming mRNA: the small subunit reads the RNA, and the large subunit joins amino acids together to form a polypeptide chain.

But there’s a catch. Ribosomes don’t speak the same language as DNA does. If they were given the raw blueprints, it’d be like you opening up a box from IKEA and finding an instruction booklet written entirely in Swedish, without any pictures to stop you from attaching table legs upside down. Of course, if you were in that situation, you’d go to Google Translate to help get the information across—and ribosomes actually do the same thing. Well, almost.

The cell has to somehow interpret the genetic message from the sequences of nucleotides from the mRNA, and translate them into the amino acid sequence of a polypeptide. Our interpreter—the cell’s equivalent of Google Translate—is another handy RNA molecule called Transfer RNA (tRNA), which floats around in the cytoplasm. In basic terms, its function is to read the message on the mRNA molecule, then goes and fetches the right amino acids and gives them to the ribosome to attach into a polypeptide chain. It does this with the help of an enzyme called amino acetyl tRNA synthase, which helps match up the amino acid to the tRNA. There are twenty different types of synthase, one for each amino acid.

Basically, it turns the language of nucleic acids into the language of proteins.

But how does the tRNA know how to read the mRNA molecule?

Well, the sequence of bases on an mRNA molecule are arranged in a specific way—in a series of non-overlapping codons. A codon is a group of three nitrogenous bases that code for a specific amino acid. The code CUU (cytosine-uracil-uracil), for example, codes for the amino acid leucine.

There are different kinds of tRNA that bind to a specific amino acid. Each one has a specific three-nucleotide sequence called an anti-codon that matches up with the complementary mRNA codon.

Some codons don’t code for an amino acid but rather act as a stop or go signal. See, if you’ve got a bunch of bases that have to be read in particular groups, you want to make sure that your tRNA starts at the right spot. Otherwise, the reading frame gets shifted one or two bases over, and suddenly your tRNA is fetching the wrong amino acids and your protein is a complete disaster. There are three different “stop” codons (UAA, UAG, and UGA) and one “start” codon (AUG). These tell the tRNA where to start reading and where to stop reading.

However, as you may have noticed from the table above, there isn’t just one codon for each amino acid. There are 61 different ways you can arrange four nucleotides into groups of three, so there are 61 codons. This means that some codons code for more than one amino acid. As you may also have noticed, the codons that code for the same amino acid all have the same first two nucleotides—it’s only the third nucleotide that changes.

This is a really important point. It means that the third nucleotide in a codon isn’t really that important. Most of the time, you could change that nucleotide and the same amino acid will still be produced. If any of the other nucleotides were changed, this could fundamentally alter what the codon codes for—another, incorrect amino acid would then be added to the polypeptide chain, and it could have a huge effect on the function of the chain. This is a mutation. But if the mutation occurs in the third nucleotide, chances are, everything will be fine.

On that note, another important thing—there isn’t one tRNA molecule for each codon. There are only 45 different tRNAs, and some can bind to more than one codon. Again, this is because the third nucleotide is the most flexible, and less important.

Next: a look at the steps of protein synthesis.

get out your VCR’s it’s time to watch The Prince of Egypt. or you can watch it here.

please don’t watch exodus: gods and kings because it’s icky and racist. you deserve better. you deserve the prince of egypt.

When

was telling me about this I used this exact comparison. I’m glad other people feel the same.
