Answer and Explanation: Hi, Homologous chromosomes - aka a homologous pair, aka homologs - are the two same chromosomes from the two parents. Homologous pairs are chromosome pairs, where one chromosome comes from the mother and the other comes from the father. They are present in diploid c...
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 ...
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...
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?
(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 ...
When it comes to genetic traits, scientists look at genes and the locus where that gene or trait encodes on the chromosome. Since humans possess two copies of each chromosome, they also have two copies of each gene and locus on those chromosomes. Each of these trait-encoding genes (or loci...
8.(a) Compare between DNA replication and transcription.[6](b)Describe how differences in the structure and organization of prokaryotic and eukaryotic genomes affect their control of gene expression.[7](c) Outline the viral reproduction cycle of HIV.[7][Total: 20] ...
performance comparison of laying hens segregating for the frizzle gene under thermoneutral and high ambient temperatures downloaded from 1476 downloaded from No significant difference was measured between heterozygous carriers and normally feathered hens, indicating that the incomplete dominant frizzle mutation ...
They focused on a subset of people with this rare condition, who also do not have the Y chromosome gene (SRY) which is usually needed for the creation of male reproductive organs. By analyzing the DNA of 78 children with this condition, they found that 9% had mutations affecting a specifi...
Genes associated with cell proliferation, immune response, and drug metabolism are differentially targeted by transcription factors between males and females in healthy lung tissue and lung adenocarcinoma samples. Gene regulatory differences between males and females are also affected by an individual’s hi...
