A) In a normal meiosis, chromosomes align precisely at the recombination site and crossovers do not change the number of genes in the recombinant chromosomes. B) The presence of duplicated sequences ...

Highly challenging to sequence and long overlooked, the human Y chromosome’s contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the complete ...

New insights into the Y chromosome, including its role in disease, should flow from the complete DNA sequencing data now achieved by two international research teams. Although it is commonly reported ...

Chromosomes are tiny, filamentous structures in the cell nuclei of living beings. They contain genes with genetic information, for example, related to the development or control of diseases. Every ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Higher yields, greater resilience to climatic changes or diseases – the demands on crop plants are constantly growing. To address these challenges, researchers of Karlsruhe Institute of Technology ...
