DNA doen't leave the nucleus but a copy of the segment (called mRNA) that codes for the protein leaves the cell and meets up with a ribosome. The ribosome will translate the copy of the DNA into a specific protein.

No, the B-subunit of hemoglobin A is a protein subunit, not a DNA molecule. Hemoglobin is composed of four protein subunits (two alpha and two beta) that come together to form the hemoglobin molecule, which carries oxygen in red blood cells. The instructions for making these protein subunits are found in the DNA of our cells.
Protein
DNA and protein
During protein synthesis, the molecule that remains in the nucleus is DNA. DNA serves as the template for the synthesis of messenger RNA (mRNA) in the process of transcription, which takes place in the nucleus. Once the mRNA molecule is synthesized, it leaves the nucleus and enters the cytoplasm where translation occurs to build the protein.
A region of the DNA molecule that stores instructions for a protein is called a gene. Genes are the basic unit of heredity and provide the code for creating proteins through a process called transcription and translation.
DNA
The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule - that's how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.
The stage at which a DNA molecule is split down the middle is replication. The first step in making a protein is RNA copying DNA.
The DNA molecule comes together and make protein. This is formed in our bodies.
No, a gene is not a distinct region of a long protein molecule. A gene is a specific sequence of DNA that contains the instructions for making a particular protein or RNA molecule. Genes are segments of DNA that are transcribed into RNA and translated into proteins. Proteins are made up of a chain of amino acids, which are encoded by the sequence of nucleotides in a gene.
