Document Summary
In a trna molecule, the nucleotide triplet that binds to its complementary codon triplet in an mrna molecule. Not a sex chromosome, autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell. Unique staining pattern, only centromere part of the chromosome absorbed the colour. The specialized heterochromatic chromosomal region at which sister chromatids remain attached after replication, and the site to which spindle fibers attach to the chromosome during cell division. The crossed strands of non-sister chromatids seen in diplotene of the first meiotic division. Regarded as the cytological evidence for exchange of chromosomal material, or crossing over. One of the longitudinal subunits of a replicated chromosome. Crossing-overs organism"s genome; in eukaryotes, a dna molecule complexed with rna and proteins to form a threadlike structure containing genetic information arranged in a linear sequence; a structure that is visible during mitosis and meiosis.
