Usage: technical; biology; genetics

Examples

• Under the microscope, the chromomeres appeared as distinct dark bands along the length of the chromosome.
• During meiosis, chromomeres become more visible as the chromatin condenses.
• The arrangement of chromomeres along a chromosome can help scientists identify specific genetic regions.
• Cytologists use chromomere patterns to map genes on chromosomes.
• Each chromomere represents a localized coiling of the DNA double helix.
