7 Molecular Genetics: From DNA to Proteins
... DNA is found in chromosomes. In eukaryotic cells, chromosomes always remain in the nucleus, but proteins are made at ribosomes in the cytoplasm. How do the instructions in DNA get to the site of protein synthesis outside the nucleus? Another type of nucleic acid is responsible. This nucleic acid is ...

Diseases with complex inheritance often demonstrate familial aggregation because relatives of an affected individual are more like ...
