DNA in the Cell The Central Dogma DNA RNA Protein
RNA Ribonucleic Acid Like DNA it is composed of nucleotides Unlike DNA it is single stranded, has a different sugar (Ribose), and contains Uracil instead of Thymine There are three main types of RNA involved in protein synthesis, messenger RNA, ribosomal RNA, and transfer RNA.
Step I: Transcription Occurs in the nucleus. Transcription is the process of converting the permanent instruction of DNA into the temporary instruction in mRNA.
Gene A gene is a segment of DNA that codes the instructions for one protein.
Transcription DNA Helicase unzips the DNA RNA Polymerase adds complimentary RNA nucleotides to the DNA of the gene. DNAmRNA Adenine =Uracil Cytosine = Guanine Guanine = Cytosine Thymine = Adenine
