Instead, the sample matched the Y chromosome
DNA of 11 men, who all came from a very small region of western Cameroon," Hammer said.
The UC Berkeley researchers demonstrated that if fewer males were the only cause of the low variability, it would mean that fewer than 1 in 4 males throughout history had passed on their Y chromosome
number change in most angiosperms proceeds by duplication of chromosomes
number changes in Carex are primarily by fission and fusion (Wahl, 1940; Davies, 1956; Hoshino, 1981).
By filling in all the gaps between the milestones, the full DNA sequence of the X chromosome
can be determined, giving a complete description of the human genetic blueprint in at least one of the 24 chromosomes
that make up the human genome.
slides pretreated with RNase I were denatured at 72[degrees]C for 2 min in 70% formamide; 2 x SSC; dehydrated in a 70%, 85%, and 100% ethanol series for 5 min each at 4[degrees]C; and incubated with the hybridization mixture for 14-18 h at 37[degrees]C in a moist chamber.

Bcg is inherited as a simple autosomal dominant Mendelian trait in crosses between classical strains of laboratory mice; it was localized to mouse chromosome

Each was then transfected with vesicular stomatitis virus (VSV) G protein and measurable virus was recovered from only the hybrid-containing chromosome
The antibiotic-resistance genes are clustered in part of a 43-kb genomic island called Salmonella genomic island I (SGI1), between the thdf and int2 genes of the chromosome
In the December issue of Nature, the Human Genome Project published the genetic sequence of the first human chromosome
