but rather how the alternation of generations life cycle is to be interpreted in the context of land plants. Therefore, the three- and four-sex models, based on the alternation of generations life cycle, have been presented for consideration, in the hope that they provide a more ...
Environmental exposure, estrogen and two X chromosomes are required for disease development in an epigenetic model of lupus. J Autoimmun 2012;38:J135-43.Strickland F, Hewagama A, Lu Q, Wu A, Hinderer R, Webb R, et al. Environmental exposure, estrogen and two X chromosomes are required...
What a piece of work is Man. And that goes double with mustard for woman. And when both are involved, hold up. Going on the assumption that we were created, by an Author or something else with some intelligence up to and including Fate (yes, I know it’s a big assumption for some ...
To analyse the similarities/differences between the twoFiglanucleotide sequences, a multiple sequence alignment was conducted by Clustal X. The 714-bp nucleotide sequences at the 3′-ends were nearly identical in the two transcripts, while the remaining sequences did not show much similarity (Figur...
To determine whether Fru is required for the binding of Bon, HP1a, and HDAC1 to Fru-target sites, immunostaining of polytene chromosomes with the respective antibodies was performed in fru mutants (Figure S4); higher resolution analysis at the distal portion of chromosome X showed that HP1a-,...
摘要: Sex determination in flies relies on the different ratio of X chromosomes to autosomes in XX females and XY males. Mammals have a male-determining Y-linked gene, but may retain dosage-related elements.DOI: 10.1016/S0960-9822(95)00012-1 被引量: 6 ...
Gender in plants: sex chromosomes are emerging from the fog. Although most plants have flowers with both male and female sex organs, there are several thousands of plant species where male or female flowers form on d... B Vyskot,R Hobza - 《Trends in Genetics》 被引量: 378发表: 2004年...
Sex Chromosomes Introduction Few people every wonder or care about their gender and why they are male or female.. Sex-determination system is a complex but fascinating progress‚ especially within reptiles‚ birds and insects. All living organisms begin with one eukaryotic cell; ins...
Hierarchical clustering of the samples was performed after removal of probes on the sex chromosomes and of probes with missing values using the 10% most variably methylated probes, as determined by standard deviation, with the Euclidean distance as the distance metric. Principal Components Analysis (...
During meiosis II: a. homologous chromosomes align and are joined through synapsis. b. non-sister chromatids of homologous chromosomes recombine. c. sister chromatids separate. d. both a and b. e. all of the above. During meiosis I: a. homologous chromosomes align and are j...
