Another difference between the stages of mitosis and meiosis is that in meiosis, homologous chromosomes pair up during metaphase instead of chromatids. In a homologous pair, one chromosome comes from the mother, and one chromosome comes from the father. Homologous chromosomes are very similar, but...
Chromosomes are contained within the nucleus in eukaryotic cells, but can also be found in some of the other organelles such as mitochondria (where DNA is packed into a small circular chromosome). In prokaryotes (e.g. bacteria), on the other hand, chromosomes form the nucleoid that is ...
What are Chromosomes? Chromosomes are threadlike structures and they exist to carry genomic information from cell to cell. They are made of protein and a single molecule of DNA. http://Females have two X chromosomes in their cells, and males have one X chromosome and one Y chromosome. Cel...
（1）一个正方体的棱长是3厘米，求它的体积 （2）一种长方体木料，体积是2100立方分米．长是20分米，宽是15分米，高是多少分米？（3）一块方钢，长2米，横截面是一个边长为4厘米的正方形．如果1立方厘米钢重7.8克，这块方钢有多重？（4）一个长方体的底面积是0.85平方米，高是0.9米，体积是多少？
Which chromosomes are autosomes and which are sex chromosomes? What chromosomes are in autosomal cells? What are the x and y chromosomes called? What kind of cells have 46 chromosomes with 23 pairs? What types of cells have chromosomes?
Chromosome banding is transverse bands that appear on chromosomes when they're exposed to different stains. Researchers often use...
During interphase, the chromosomes are not visible using a light microscope. Why would this be important for a cell? What is the significance of meiosis in terms of the genetic content of the cells produced? How do chromatin and chromosomes compare to one another?
Sex Differences in Alcohol Use: Is It All About Hormones? Risky alcohol use and alcohol use disorders (AUD) are a rising problem in women, yet a major disparity in our understanding of what drives alcohol consumpt... XJ Maddern,LT Ursich,B Grace,... - 《Endocrinology》 被引量: 0发表...
Each sex chromosome is composed of two pseudoautosomal regions (PAR1 and PAR2), which are conserved homologous sequences on the X and Y chromosomes, in addition to a sex chromosome-specific region which contains a greatly increased amount of genetic material on the X chromosome relative to the...
The localization of AtTPS genes on all five chromosomes reflects the dynamics of the Arabidopsis genome; however, several AtTPS genes are clustered and ... S Aubourg,A Lecharny,J Bohlmann - 《Molecular Genetics & Genomics》 被引量: 694发表: 2002年 Stochastic genome-nuclear lamina interactions ...
