ChromosomeandDNA h 1 第一节概述 一、染色体与DNA的关系 1、染色体的发现：1848年，Hofmeister在鸭跖草的小孢子母细胞中发现染色体 2、遗传的染色体学说：1902W.Sutton(美)&T.Boveri(德)基因是染色体的一部分 h 2 3、染色体学说的直接证据布里吉斯（Bridges,C）发现X染色体的不分离现象将基因定位在X染色体上4、...
The very long strand of DNA which further contains many genes (hundreds to thousands) makes up a chromosome. The genes are arranged in a particular sequence and have a particular location on the chromosome (called its locus). In addition to DNA, chromosomes also contain many ...
Sex chromosome, either of a pair of chromosomes that determine whether an individual is male or female. The sex chromosomes of human beings and other mammals are designated by scientists as X and Y. In humans the sex chromosomes consist of one pair of th

The structure and location of chromosomes are among the chief differences between viruses,prokaryotes, andeukaryotes. The nonliving viruses have chromosomes consisting of eitherDNA(deoxyribonucleic acid) orRNA(ribonucleic acid); this material is very tightly packed into the viral head. Among organisms wit...
Erratum: The DNA sequence of human chromosome 21: The chromosome 21 mapping and sequencing consortium (Nature (2000) 405 (311-319)) Genome mapping data have been compiled into GDB (Genome Data Base) with international collaborative efforts. The GDB has become an indispensable internatio... M ...
The structure, abundance and location of repetitive DNA sequences on chromosomes can characterize the nature of higher plant genomes. Here we report on three new repeat DNA families isolated from Anemone hortensis L.; (i) AhTR1, a family of satellite DNA (stDNA) composed of a 554–561bp lo...
Phylogenetic trees of DNA sequences along LG1 are consistent with occasional X-Y recombination in all species where LG1 is sex linked. These patterns argue against one of the main potential causes for turnovers, namely the accumulation of deleterious mutations on nonrecombining chromosomes. Sibship...
