HG 69.45-69.65

Dark brown sediment with clasts ranging from small to medium in size. The clast shape ranges from angular to sub-rounded. Lineations are abundant throughout the sample. Comet structures and grain crushing/stacking are also present in minor amounts.

HG 75.45-75.60

Dark brown sediment with clasts ranging from small to medium in size. The clast shape ranges from angular to sub-rounded. Lineations are commonly seen throughout the sample. Grain crushing/stacking can also be seen along with varying amounts of rotation structures and comet structures.

HG 77.35-77.45

Brown sediment with clasts ranging from small to medium in size. The clast shape ranges from angular to sub-rounded. Lineations are the most abundant in this sample, along with grain crushing. A few comet structures and rotation structures can also be seen throughout the sample.

HG 78.45-78.55

Coarse sediment with grains ranging from small to large . Clast shape ranges from sub-angular to sub-rounded. Grain crushing is common throughout the sample, with many grains being crushed into one another. A few lineations and rotation structures can also be seen throughout.

HG 115.30-115.45

Dark brown sediment with clasts ranging from small to medium. The clast shape ranges from angular to sub-rounded. Edge-to-edge grain crushing and grain stacking are abundant throughout this sample. Some lineations and rotation structures can also be seen in minor amounts.

HG 116.45-116.55

Light brown sediment with clasts ranging from small to large. The clast shape ranges from angular to rounded. Rotation structures are abundant in this sample. Some necking structures and comet structures can also be seen, along with a few lineations.

HG 174.30-174.45

Brown sediment with two different domains; one coarse grained, and one finer grained. In the coarse grained domain, clasts range from small to large in size. The clast shape ranges from sub-angular to rounded. Rotation structures and edge-to-edge grain crushing is commonly seen. In the finer grained domain, clasts are mainly small, with a few larger clasts, and there is an abundance of lineations.

HG 177.35-177.45

Dark brown sediment with organic matter. There are two main domains; a coarse grained domain, and a finer grained domain. The coarse grained domain contains grains ranging from small to medium in size, and angular to sub-rounded in shape. In the coarse grained domain, grain crushing/stacking is common, with a few lineations and rotation structures. In the finer grained domain, grains are small and range from sub-angular to sub-rounded in shape. Lineations are abundant in this domain.

Phosphorylation du CTD de l'ARN polymérase II et impact de l'histone H2A.Z sur le positionnement des nucléosomes chez S. cerevisiae

La phosphorylation du domaine C-terminal de l’ARN polymérase II permet à ce complexe protéique d’exécuter la transcription des gènes, en plus de coupler à la transcription des événements moléculaires comme la maturation des ARNm. Mes résultats montrent que même si cette phosphorylation suit un patron similaire à l’ensemble des gènes, il existe des exceptions pouvant être dues à des mécanismes alternatifs de phosphorylation du CTD. Le présent ouvrage s’intéresse également au rôle qu’occupe la variante d’histone H2A.Z dans l’organisation de la chromatine. Des études précédentes on montré que le positionnement de certains nucléosomes le long de l’ADN serait influencé par H2A.Z et aurait une influence sur la capacité de transcrire les gènes. Par une approche génomique utilisant les puces à ADN, j’ai cartographié l’impact de la délétion de H2A.Z sur la structure des nucléosomes. Enfin, des résultats intéressants sur la dynamique d’incorporation de H2A.Z à la chromatine ont été obtenus.
