Explain how genes encode proteins?
A gene is a section of DNA containing bases AT/GC which encodes for a protein. The genes are present in the nucleosome of the nucleolus. When a gene is needed for transcription RNA polymerase will be recruited to the gene, transcribing mRNA (uracil instead of Thymine) which transports out of the nuclear pores to the ribosomes on the RER (rough endoplasmic reticulum). Ribosomes carry out translation using the codon (three nucleic bases) to code for a complementary anti-codon. tRNA brings the correct amino acid to add to the growing primary sequence of the polypeptide.
