To become a forensic biologist, you typically major in biology, forensic science, or a related field such as molecular biology or genetics. It is important to take courses in biology, chemistry, genetics, and forensic science to develop the necessary skills for this career. Internships or research opportunities in forensic labs can also be beneficial.
Some universities offer Forensic Science as a major. Since forensic science involves a lot of biological techniques, Biology, Molecular Biology, and Biochemistry are some possibilities. Just remember that picking the major is just the start of it - you need to make sure you get the right courses to prepare you. You'll need courses in population biology, biochemstry, molecular biology, genetics, and statistics.
A scientist who studies DNA double helix is called a molecular geneticist or a geneticist specializing in molecular biology.

A forensic scientist has more than three tasks or responsibilities. The main areas are drugs and toxicology, Biology, and chemistry.
Public Health. Cancer. Aging. Endocrinology. Cellular biology. Molecular biology. Pharmacology. Neuroscience. Genetics. Virology.
The title of "forensic scientist" is a more general label, while forensic biologists focus specifically on living forensics. I would guess that forensic biology falls under the umbrella of forensic science.
