DNA replication, Transcription and Translation problems

 

  1. It is S phase of the cell cycle, and time to replicate the cell’s DNA. Using the following strand of DNA as a template, create the complementary strand:

GCTCCTTACGGGCCCAATGACCTGAATGTACGAGATCCCATCCTT

  1. It is now time to make a protein. Using the same stand of DNA, transcribe it to mRNA, then translate to an amino acid sequence (use the codon table below).
