(a) Explain ATP synthesis. (b) Describe the electron transport chain process of ATP synthesis. (c) What is an electron transport chain? The sites of protein synthesis in the cells are: A. Mitochondria B. Lysosomes C. Ribosomes D. Nucleus ...
Ribosome The complex ofRNAand proteins where proteins are synthesized. To correctly initiateprotein synthesisribosomes need to bind to a specific ribosome binding site on the mRNA. The ribosome is composed of many proteins and a few, mostly large,ribosomal RNAmolecules. ...
Where are all of the NADH and FADH produced and where are they used to make ATP? Cytoskeletal filament found in cilia and flagella are: a. smooth ER b. ribosomes c. nucleolus d. microtubule Centrioles forming the bases of cilia and flagella are commonly referred to as what?
Host cell DNA is found in some papovavirus particles, and cellular ribosomes are incorporated in arenaviruses. Several copies of the complete viral genome may be enclosed within a single particle, or viral particles may be formed that contain no nucleic acid (empty particles) or that have an...
A new internal-ribosome-entry-site motif potentiates XIAP-mediated cytoprotection. Nat Cell Biol 1999; 1: 190–2. 7 Martinez-Salas E, Ramos R, Lafuente E, Lopez de Quinto S. Functional interactions in internal translation initiation directed by viral and cellular IRES elements. J Gen Virol ...
with a single P1-P2 dimer, suggesting that only one CTD is sufficient for the interaction with RTA. These results are consistent with previous studies, which showed that RTA interacts with yeast ribosomes via fast and slow interactions, where the fast interactions occur with the stalk P-...
(a) Are the stomata of the leaf open or closed? Explain. (b) Describe the functions of guard cells.What is unusual about cells in the Xylem? a. They have more ribosomes than other cells. b. They are an additional nucleus ( they have multinuclear). c. The...
However, the ubiquitin ligases, biochemical consequences, and physiologic pathways linked to these modifications are not known. Here, we show in mammalian cells that the ubiquitin ligase ZNF598 is required for ribosomes to terminally stall during translation of poly(A) sequences. ZNF598-mediated ...
This is not the result of any difference in affinity of the two operator RNAs for coat protein, since their binding behaviors in vitro are indistinguishable (Fig. 2). Do these observations imply that the extra AUGs are bound by ribosomes? N-terminal sequence analysis of the replicase protein...
This requires presence of a structured RNA element, known as, Internal Ribosome Entry Site (IRES) in their 5′ untranslated regions (UTRs). Experimental demonstration of IRES in UTR remains a challenging task. Computational prediction of IRES merely based on sequence and structure conservation is ...
