Abstract:
The gene coding for rat heart fatty acid-binding protein (FABP), along with 1.2 kb of its 5'-untranscribed region, was amplified by PCR, cloned and sequenced. As in other FABP genes, the coding sequence is interrupted by three introns of 3.4, 1.4 and 1.1 kb, respectively. Fluorescence in situ hybridization mapping revealed that the gene is located on chromosome 5q36. Using intron-specific primers flanking exon 2, unspliced primary transcript RNA of the FABP gene was detected in a preparation of total RNA isolated from rat heart, proving that the cloned gene is expressed in adult cardiac tissue.

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
