Where are the instructions for assembling proteins contained?
Proteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein . The genetic code is a set of three …
Protein folding is the physical process by which a protein chain is translated to its native three-dimensional structure typically a "folded" conformation by which the protein becomes biologically functional. Via an expeditious and reproducible process a polypeptide folds into its characteristic three-dimensional structure from a random coil. Each protein exists first as an unfolded ...
They are assembled by the chromatin assembly factor-1 (CAF-1) complex which consists of three subunits (p150 p60 and p48). Newly synthesized H3 and H4 are assembled by the replication coupling assembly factor (RCAF). RCAF contains the subunit Asf1 which binds to newly synthesized H3 and H4 proteins .
Protein primary structure is the linear sequence of amino acids in a peptide or protein . By convention the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end. Protein biosynthesis is most commonly performed by ribosomes in cells. Peptides can also be synthesized in the laboratory. Protein primary structures can be directly ...
DNA sequences that carry the instructions to make proteins are referred to as coding sequences. The proportion of the genome occupied by coding sequences varies widely. A larger genome does not necessarily contain more genes and the proportion of non-repetitive DNA decreases along with increasing genome size in complex eukaryotes.
In molecular biology messenger RNA (mRNA) is a single-stranded molecule of RNA that corresponds to...
