- functions of protein in a eukaryotic cell.arrow_forwardThe relationship between the nucleotide sequence of an mRNA and the DNA strand from which it is transcribed. Messenger RNAs are synthesized by RNA polymerases that read along a DNA template strand in the 3'→5' direction, polymerizing ribonucleotides in the 5'→3' direction. Give the nucleotide sequence (5'→3') of the DNA template strand from which the following mRNA segment was transcribed: 5'-UAG UGA CAG UUG CGAU-3’arrow_forwardProtein Synthesis- Transcription and Translation answersarrow_forward
