Sure! Let's fill in the blanks in your text related to DNA transcription and translation:
DNA carries the cell's genetic information; however, it cannot leave the nucleus. Because of this, it copies part of its nucleotide sequence into a complementary copy of RNA during the process called transcription. During this process, the enzyme, RNA polymerase, separates the DNA strands. One strand of DNA acts as the template strand from which nucleotides are assembled into a strand of RNA. Each three-letter sequence on the mRNA is called a codon. The start codon is AUG and the three stop codons are UAA, UAG, and UGA. Once the mRNA leaves the nucleus, it goes to the ribosome to prepare for protein synthesis, which is called translation. During this process, a tRNA (transfer RNA) molecule brings the amino acids to the ribosome. The amino acids are hooked together by peptide bonds. The tRNA is able to match up to the mRNA by the anticodon. When the stop codon is reached, the polypeptide chain is released into the cytoplasm.
