AGO4 regulates entry into meiosis and influences silencing of sex chromosomes in the male mouse germline The four mammalian Argonaute family members are thought to share redundant functions in the microRNA pathway, yet only AGO2 possesses the catalytic "slicer" function required for RNAi. Whether ...
Where is DNA housed in the prokaryote cell? What are the main organelles in a eukaryotic cell? Is the nucleolus a plant cell or a animal cell? What are organelles? Why would a pancreatic cell have many ribosomes? Why does a pancreatic cell have many ribosomes?
Answer and Explanation:1 Fertilization of an egg, in a female human for instance, usually occurs en route to the uterus via the fallopian tube. After ovulation, as the egg... Learn more about this topic: Fertilization | Definition & Process ...

What is the ploidy of a human sperm? Ploidy is the number of homologous sets of chromosomes in a biological cell. The ploidy of cells can vary within an organism. In humans, most cells are diploid (containing one set of chromosomes from each parent), but sex cells (sperm and egg) are...
Where is DNA located in the prokaryotic cells?Prokaryotic Cells:Prokaryotic cells form unicellular organisms, unlike eukaryotic cells, which form multicellular organisms. Prokaryotes have less DNA compared to eukaryotes and contain circular DNA instead of compact chromosomes. Examples of prokaryotes include ...
that most females have two X chromosomes and most males have one X and one Y chromosome. But in every thousand humans, there are typicallya few whose biological sex doesn't match their sex chromosomes, such as XX males and XY females, or whose sex chromosome combinations are not even XX ...
A test to assess the presence of an abnormal number of chromosomes (aneuploidy and diploidy) in sperm using fluorescence in situ hybridization. The test scores the percentage of spermatozoa with chromosomal abnormalities in a sperm sample. Typically, the analysis is performed on the chromosomes most...
aThe objective of clustering was to minimize MDL using GAs where chromosomes are formulated to represent components combinations in clusters generations. The number of clusters is determined a priori based on the DSM structure. 宗旨成群将使用气体使MDL减到最小,染色体在群世代被公式化代表组分组合。 群...
During mitosis in vertebrate cells, however, the most prominent landmarks of nuclear structure, the nuclear envelope and the nucleolus, are broken down. Chromosomes condense and congress to a flat metaphase plate which lacks the obvious three-dimensional spatial organisation of the nucleus. A key ...
