1. Describe how the DNA code is translated into messenger RNA.
The DNA code is translated into messenger RNA when the RNA polymerase
binds to it and makes the mRNA copy. The RNA polymerase reads each
nucleotide and brings in complementary nucleotides, and binds them
together, which makes the mRNA strand.
2. How is the RNA molecule a “script” for the protein production process?
The RNA molecule is a "script" for the protein production process because
the ribosomes in the cytoplasm read the RNA sequence, and they use it to
form an amino acid chain based on the sequence of nucleotides in the RNA.
3. What is the function of hemoglobin in the body?
Hemoglobin is exclusively found in red blood cells (RBCs). The major form
is hemoglobin A. Its main function is to transport oxygen from the lungs to
the capillaries of the tissues. Hemoglobin is a tetramer of two identical
dimers made of alpha and beta polypeptide chains.
