DNA Synthesis during Meiotic Prophase in Male Mice

Most of the structural genes are composed of single copy sequences in all examined organisms, and therefore this sequence is considered to be of greatest importance for coding proteins. Any correlation between minimum DNA content and complexity is unclear because there can be no obvious explanation to account for the reason why broad beans have nearly twice as much structural DNA as peas and four times as much structural DNA as mung beans, especially because they all belong to the same Leguminosae family. Therefore, it is believed that much of the single copy DNA is not required for mRNA synthesis. Only a small fraction of mRNA is hybridized to unique DNA under saturating DNA conditions. Indeed, typically 1-10% of the unique DNA is transcribed into mRNA. In addition, a significant portion of the single copy sequences in all higher plant genomes contain less than 2000 base pairs. In mung bean and cotton, sequences in excess of 1200-1800 base pairs constitute most of the single copy DNA and about 40-60% of the nuclear genome.

Evidence for a role for DNA polymerase β in …

It is interesting that we observe pol β foci at the ends of bivalents. It is known that there is a high frequency of recombination near the ends of chromosomes in male eutherian mammals (). Thus, the presence of pol β at the ends of bivalents might suggest a role for this enzyme in a recombination pathway (). Alternatively, pol β may participate in DNA synthesis or repair of terminal sequences in germ cells.

DNA synthesis during zygonema and the other interval is during pachynema and resembles repair synthesis.

36 P.M. DEY, M.D. BROWNLEADER AND J.B. HARBORNE threads and in fact consist of a pair of sister chromatids which are identical and held together by a centromere. In addition, a complex of RNA and protein associated with DNA called a lateral component or lateral element is deposited along the chromatids during leptonema. Lateral element synthesis is conducted by both sister chromatids. In addition to chromosome condensation and lateral element synthesis, the telomeres of the chromosomes begin to associate with a region of the nuclear envelope called the attachment site, which is devoid of nuclear pores and slightly thickened. This site may align homologous chromosomes.
