Transcription and Translation
... RNA = three different functions: • Ribosomal RNAs – (rRNA) makes us the ribosome. Each ribosome consists of about 60% ribosomal RNA and 40% protein. • Messenger RNAs – (mRNA) "record" information from DNA in the cell nucleus and carry it to the ribosomes. • Transfer RNAs- (tRNA) delivers amino acids ...

Eukaryotic Gene Regulation
... Genes are regulated in a variety of ways by enhancer sequences located before the point at which transcription begins. An enormous number of proteins can bind to different enhancer sequences, which is why eukaryotic gene regulation is so complex. Some of these DNA-binding proteins enhance transcript ...
