Chromosome pairing
WebChromosomes are very long structures consisting of two DNA polymers, joined together by hydrogen bonds connecting complementary base pairs. A chromosome is divided into segments of double-stranded DNA called genes. Each gene is further divided into three nucleotide subsegments called codons WebChromosome pairing refers to the lengthwise alignment of homologous chromosomes at the prophase stage of meiosis. Most sexually reproducing organisms have two sets of chromosomes, one set inherited from each parent.
