this liquid environment is packed full of cellular machinery and structural elements. In fact, the concentrations of proteins inside a cell far outnumber those on the outside — whether the outside is ocean water (as in the case of a single-celled alga) or blood serum (as in the case of...

Kingdom Plantae is a taxonomic group that includes ferns, algae, liverworts, and green plants. They are mostly eukaryotic and multicellular, with a few exceptions. At the cellular level, they have cell walls make of cellulose and a specialized organelle called a chloroplast, which allows them t...
The nucleus is a big organelle. It controls the activities of the cell. The nucleus contains chemical instructions in the form ofDNA. DNA Strands Cytoplasm The cytoplasm is a jelly-like liquid that fills the cell. It contains enzymes that accelerate the chemical reactions that take place within...
True or false? During interphase, a cell is metabolically active. Mitochondria, a eukaryotic cellular organelle, most likely originated from prokaryotic proteobacteria. Is the statement true or false? Translation occurs within the cytoplasm of...
lies laterad to the nucleus and embrances it partially.There is a pentalaminar organelle in the neck of the spermatozoon.Axoneme is typical 9+9+2 pattern.The two mitochondrial derivatives are partially crystallized.The sperm length of G.sedakovii is shorter than that of G.gratiosa.The cross...
The thylakoid transit peptide of tobacco oxygen-evolving enhancer protein contains a minimal ten amino acid sequences for thylakoid lumen transports. This
Active TNK1 induces growth factor-independent proliferation of lymphoid cells in cell culture and mouse models. One unusual feature of TNK1 is a ubiquitin-association domain (UBA) on its C-terminus. Here, we characterize the TNK1 UBA, which has high affinity for poly-ubiquitin. Point mutations...

2E). No observable changes in the morphology or growth rate of intracellularly replicating parasites were observed (see Fig. S1A in the supplemental material). TgFER2 therefore does not function in cell division or replication but is essential for completion of Toxoplasma’s lytic cycle. Download...
