Symmetric karyotype has more metacentric chromosomes. DNA - DNA stands for deoxyribose nucleic acid. These very unusual chromosomes are called 'lampbrush chromosomes' due to their resemblance to the brushes used in earlier times to clean kerosene lamps. Explain why materials with high mmm values, such as hot glass and Silly Putty { }^{\circledR}, when stretched slowly, undergo large elongations before failure. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Treatment of DNA filaments by protease failed to break up the filaments. The next largest unit of the chromosome is the quarter chromatid. How do DNA genes chromosomes and genomes relate to one another. Now chromosomes are going to be housed within the nucleus. haploid chromosome length, C: chromosome length, R: ratio between the largest and the smallest chromosomes in the complement, r: arm ratio , A 1 and A 2 : intra- and interchromosomic asymmetry . The first chromosome, one, is the largest chromosome, while the 22nd chromosome is the smallest.
