What is the difference between chromatin and chromatid? Chromosomes: A chromosome is a structure in the nucleus tightly packaged with DNA. The DNA is supported by histones around which it is coiled. The chromosomes are vital in ensuring that the replication and distribution of DNA in the cell ...
Does a homologous chromosome pair actually has four chromosomes? What is the difference between replication and duplication in chromosomes? What is the difference between autosomes and sex chromosomes? Does a 2n individual have homologous chromosomes or two copies of each chromosome?
each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent, namelymale parent and female parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known...
(Also known as loss of heterozygosity) is the reduced fitness of a certain population that results from breeding between close genetic relatives. Sex-determining region of the Y chromosome (SRY). The gene located on the Y chromosome that is responsible for male sex determination in almost all ...
What mechanism and immune cell in specific does the body use to eventually bring the HIV virus back down to low levels? Are two chromatids of a chromosome genetically identical with no difference of even bases? What is difference between tissue culturing and cloning?
Recent studies of mouse models such as the four core genotypes have begun to distinguish between the direct effects of sex chromosome complement (XX vs. XY) and hormonal effects. Several lines of evidence implicate epigenetic processes in the control of sex differences, although a great deal of ...
A Novel Mutation of PARK-2 Gene in a Patient with Early-onset Parkinson's Disease Between 3鈥 5% of all patients with Parkinson's disease (PD) have onset before the age of 40 years, which is likely related to genetic causes. Parkin gene m... T Alafifi,ARA Bakhsh,M Elbashari,......
The notion that the highly differentiated mammalian gametes would have gamete-specific genes that are important for their differentiation and function is almost self-evident. The structural components of these specialized cells, such as proteins in the a
receives the full diploid complement (and does not wind up with four copies). The process by which sperm and egg cells split chromosomal copies to become haploid (have one copy of each chromosome) is meiosis. These similar pairs homologous chromosomes, with copies of the gene from each parent...
1.With the aid of the two concepts of diversity between any two samp le s and total diversity martrix of orderd samples, diversity matrix method is pres ented for clustering orderd samples.借助于任意两个样品之间的差异度和有序样品的全差异矩阵的概念,提出有序样品聚类的全差异矩阵法。 2.Based...
