The process of forming a protein begins with transcription in the nucleus, where RNA polymerase binds to a promoter, synthesizing mRNA through complementary base pairing, replacing thymine (T) with uracil (U), and ends with a termination sequence followed by mRNA modification. The mRNA then exits the nucleus and enters the cytoplasm, where translation occurs on ribosomes; mRNA codons are read by tRNA anticodons to assemble amino acids into a polypeptide chain. This sequence continues until a stop codon is reached, resulting in a new protein.

- 1. summarize the process of forming a protein from a base sequence in DNA. use the following key points and terms: Transcription (location in the cell, promoter, RNA polymerase, mRNA, complementary base pairing with U substituted for T, termination sequence, modification of mRNA before leaving nucleus) and translation (location in cell, ribosomes, mRNA, codon, genetic code, tRNA, anticodon, amino acid, peptide bonds, stop codon, new polypeptide)
