What are the primary, secondary, tertiary, and quaternary structures of proteins? What occurs during the primary, secondary, tertiary and quaternary structures of protein synthesis? What is the tertiary structure of a protein? What are the main types of ...
Ribosome profiling has the power to interrogate —in vivoand on a global scale — what is being translated, how this translation is regulated and where in the cell the translation of specific sets of proteins occurs. Ribosome profiling, which involves th
What occurs at the nucleolus? What is cell structure? What is cell theory? What cells contain a nucleus and membrane-bound organelles? What is the function of nucleus pulposus? Explain. What does cell theory apply to? What is the living part of a cell?
In addition to splicing, ribozymes catalyze the assembly of amino acids into proteins during the process of translation. Translation occurs when genetic information in messenger RNA (mRNA) is decoded into a sequence of amino acids through the activity of ribosomes. Ribosomal RNA (rRNA), a main ...

•Ribosomes:Found in the cytoplasm of all organisms and elsewhere in eukaryotes, these are the protein "factories" of cells, and consist of two subunits. They contain the sites upon wheretranslationoccurs. Eukaryoteshave more complex cells, containing _organelles, which are surrounded by the same...
Glycolysistakes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae). What's a ribosome in a cell?
For example, a possible mRNA sequence might be UUUAAAGGG, where each letter represents a nucleotide. The normal codons would thus be UUU, AAA, and GGG. If an error occurs in the mRNA, it may result in the sequence GUUUAAAGGG. The ribosome would read the codons as GUU, UAA, and AGG...
β-selection occurs in the thymic cortex, but the cell type(s) required for self-peptide presentation at this checkpoint are not known. cTECs and DCs are the main cortical antigen presenting cells, but, given their relatively low cellularity, there may be significant competition for DN cells ...
This action would explain the rapid inhibition of DNA replication (which occurs at a site on the membrane) that ensues when cells are exposed to concentrations of tetracycline in excess of that needed for protein inhibition. In addition, tetracyclines appear to inhibit adhesion of bacteria to ...
