Ordered arrangement of chromosomes
WebHow are chromosomes one to 22 ordered in a karyotype? (A) By increasing size and in matching pairs. (B) By decreasing size and in homologous pairs. (C) By decreasing size and in random pairs. Or (D) by the number of genes they contain and in matching pairs. A karyotype allows for a visualization of chromosomes from an organism. WebDNA, genes and chromosomes DNA - deoxyribonucleic acid. This molecule consists of two long chains of chemicals; nucleotides that twist around each other in a double helix. DNA can be copied or 'replicated' - each strand acts as a template for the generation of the complementary strand.
