DNA Rap For Honors Biology

DNA Rap For Honors Biology

lyrics:Here's a rap about DNA Try to understand what I'm 'bout to say DNA is what makes us us So hear me rap about the processes Replication, transcription, and translation Rappin' to this is better than vacation It all starts off with replication When a cell copies its DNA information The enzyme polymerase unzips DNA So the hydrogen bonds between the base pairs breaks This process follows the rules of base pairing- The principle that bonds do certain sharing Chargaff's rule A=T and G=C Shows the nitrogenous bases' special links Adenine and thymine, guanine and cytosine Are the bases linked by hydrogen bonds in between DNA strands unwind when hydrogen bonds break Each strand is now a double helix template Complementary bases attach to make a copy DNA polymerase proofreads to make sure it's not sloppy Transcription is copying DNA to RNA In this process is RNA polymerase It binds to DNA at a promoter Which tells RNA polymerase to "go here" Then RNA polymerase separates strands of DNA And uses one strand as a kind of template Adenine links to uricil, and guanine to cytosine And that's how strands of RNA are made Translation is the process that comes next It decodes mRNA like reading a text In the mRNA is a codon that is read It's made of three nucleotides that specify an amino acid The instructions from mRNA show the order In which amino acids should be joined together Cells use mRNA to produce proteins So cells can carry out processes in our bodies A ribosome is made of rRNA Which is where mRNA attaches to begin this phase As each codon moves through the ribosome space The right amino acid is attached to the polypeptide chain tRNA knows which amino acid for a codon to go on because its bases match mRNA codons ribosomes work like an assembly line making and breaking peptide bonds at the same time this process keeps going until a "stop" codon The protein is made and it's all done.
