Biology on Instagram: "The transcription and translation of genetic information are the two main steps of gene expression. During transcription, the enzyme RNA polymerase copies a gene’s DNA sequence into messenger RNA (mRNA) by pairing complementary RNA nucleotides with the DNA template strand, replacing thymine (T) with uracil (U). Next, during translation, the mRNA travels to the ribosome, where transfer RNA (tRNA) molecules read the mRNA codons and bring the corresponding amino acids. These
