Figure 4From: Cytogenetic analysis of quinoa chromosomes using nanoscale imaging and spectroscopy techniquesCompositional maps of chromosomes. (A) DNA. (B) Protein. (C) Non-carbonaceous compounds. (D) Composite image. (E) Absorbance reference spectra of 1 nm of albumin and nucleic acid. The scale bars of (A) and (B) are in nanometers and (C) is in optical density. Two chromosomes are marked in red (1) and green (2) for comparison.Back to article page
