Elevated repetitive transcripts at stages with less condensed chromatin ultrastructure (a) TEM images showing nuclear periphery and cytoplasmic organelles at 2.7, 4.5 and 6.0 hpf. Scale bar equals 1 m. (b-e) Quantitative RT-PCR showing increasing levels of transcripts derived from repetitive elements following the onset of zygotic transcription. A decline in transcript levels at 6.0 hpf correlates with the onset of heterochromatin formation. All p-values were calculated using the students t-test, error bars indicate SEM.
