Label the steps of transcription in order, beginning with step one. Free RNA nucleotides pair with the complementary DNA nucleotides on one strand of DNA. The mRNA molecule breaks away as the DNA strands rejoin. RNA polymerase unzips the DNA molecule.
is a single-stranded nucleic acid that moves the DNA code for from the to the .
What begins the process of transcription?
Label the steps of translation that led to gene expression. A peptide bond is created between the first two amino acids formed. Once a protein is formed, the gene for a particular trait is expressed. A chain of amino acids is formed, creating a protein. The first codon of mRNA attaches to a the anticodon of tRNA to form a chain of amino acids.
The nucleic acid contains the genetic information for all of the structures and functions of an organism.
Identify the three main stages of translation. Check all that apply.
