Eukaryotic DNA methylation
TLDR
The introduction of artificially methylated DNA sequences into individual eukaryotic cells by microinjection or transformation may provide the means to elucidate questions in the regulation of gene expression in these organisms.
Domains of DNA methylation in eukaryotes : studies on their structure and function
TLDR
Although the frequent occurrence of differentially methylated multisequence families precluded an assessment as to whether all transcribed sea urchin gene sequences reside in the unmethylated compartments, results obtained are consistent with this hypothesis.

Deoxyribonucleic acid methylation and chromatin organization in Tetrahymena thermophila
TLDR
Pulse-chase studies showed that labeled MeAde remains preferentially in linker DNA during subsequent rounds of DNA replication; i.e., there is little, if any, movement of nucleosomes during chromatin replication, implying that nucleosome may be phased with respect to DNA sequence.

Methylation of mouse ribosomal RNA genes.
TLDR
The rDNA methylation level might be correlated directly with the number of rDNA genes and there are discrete hypomethylation sites at similar sites for both Hpa II and Hha I and show a tissue-specific pattern.
5-Methylcytosine in eukaryotic DNA.
TLDR
Methylation of eukaryotic DNA has been proposed to function in many ways, including control of transcription, maintenance of chromosome structure, repair of DNA, establishment of preferred sites for mutation, oncogenic transformation, and, in certain systems, protection of DNA against enzymatic degradation.

Specific DNA methylation sites in the vicinity of the chicken β-globin genes
TLDR
This technique is used to provide a correlation between DNA methylation and the activity of the chicken β-globin genes and it is shown that the overall content of 5-methylcytosine in DNA does not vary significantly between different tissues of the same organism.
Rare Bases in Animal DNA
TLDR
This work has shown that 6-MeAde and certain N2-methylated derivatives of guanine have been recently discovered in appreciable amounts in bovine and human sperm DNA.
Methylation of DNA in developing sea urchin embryos.
Direct detection of methylated cytosine in DNA by use of the restriction enzyme MspI.
TLDR
The results reveal a symmetric methylation of both strands at this sequence in calf thymus DNA, in contrast to the CCGG sequence in other eukaryotic DNAs from organisms like Neurospora, Drosophila and Herpes virus, which proved to be undermethylated at this sequences.
X inactivation, differentiation, and DNA methylation.
TLDR
A model based on DNA methylation is proposed to explain the initiation and maintenance of mammalian X inactivation and certain aspects of other permanent events in eukaryotic cell differentiation using sequence-specific DNA methylases that methylate unmethylated sites with great difficulty but easily methylate half-methylated sites.
