Что (кто) такое homologous$35713$ - определение

SET OF ONE MATERNAL AND ONE PATERNAL CHROMOSOME THAT PAIR UP WITH EACH OTHER INSIDE A CELL DURING MEIOSIS. HOMOLOGS HAVE THE SAME GENES IN THE SAME LOCI
Homologous Chromosomes; Homologous chromosomes; Homologs
  •  During the process of meiosis, homologous chromosomes can recombine and produce new combinations of genes in the daughter cells.
  • Diagram of the general process for double-stranded break repair as well as synthesis-dependent strand annealing.
  • Karyotype}}
  •  Sorting of homologous chromosomes during meiosis.
  • 1. Meiosis I 2. Meiosis II 3. Fertilization 4. Zygote
Nondisjunction is when chromosomes fail to separate normally resulting in a gain or loss of chromosomes. In the left image the blue arrow indicates nondisjunction taking place during meiosis II. In the right image the green arrow is indicating nondisjunction taking place during meiosis I.

Homologous chromosome         
A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during fertilization. Homologs have the same genes in the same loci where they provide points along each chromosome which enable a pair of chromosomes to align correctly with each other before separating during meiosis. This is the basis for Mendelian inheritance which characterizes inheritance patterns of genetic material from an organism to its offspring parent developmental cell at the given time and area.
Homologous series         
  • Normal boiling points of straight chain alkanes
SERIES OF CHEMICAL SUBSTANCES WITH THE SAME GENERAL FORMULA, VARYING BY A SINGLE PARAMETER
Homologous Series
In organic chemistry, a homologous series is a sequence of compounds with the same functional group and similar chemical properties in which the members of the series can be branched or unbranched, or differ by molecular formula of and molecular mass of 14u. This can be the length of a carbon chain, for example in the straight-chained alkanes (paraffins), or it could be the number of monomers in a homopolymer such as amylose.
Homologous recombination         
DNA RECOMBINATION PROCESS
Homolog recombination; Legitimate recombination; Recombinational repair; General recombination; Recombination repair; Homologous recombinational; Homologous recombination deficiency; Strand Invasion; Homologous recombination repair
Homologous recombination is a type of genetic recombination in which genetic information is exchanged between two similar or identical molecules of double-stranded or single-stranded nucleic acids (usually DNA as in cellular organisms but may be also RNA in viruses). It is widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks (DSB), in a process called homologous recombinational repair (HRR).
