Welcome to the Molecular and Cell Biology taskforce of WikiProject Molecular Biology. If you have any questions about articles or are generally seeking advice, you're encouraged to ask at the talkpage of WikiProject Molecular Biology , the centralized point for discussion, thank you .
Molecular biology is the study of the molecular underpinnings of the biological phenomena, focusing on molecular synthesis, modification, mechanisms and interactions. Biochemistry is the study of the chemical substances and vital processes occurring in living organisms .
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Biomolecules are an important element of living organisms. They are often endogenous, [2] i.e. produced within the organism, [3] but organisms usually also need exogenous biomolecules, for example certain nutrients, to survive. Biomolecules and their reactions are studied in biology and its subfields of biochemistry and molecular biology.
Molecular Biology of the Cell has been described as "the most influential cell biology textbook of its time". [2] The sixth edition is dedicated to the memory of co-author Julian Lewis, who died in early 2014. The book was the first to position cell biology as a central discipline for biology and medicine, and immediately became a landmark ...
What was the molecular mechanism that allows the association of the amino acids with their triplet codons? [1] What were the biochemical paths from individual bio-building blocks like amino acids or nucleic acids to functional polymers such as proteins and DNA?
The central dogma of molecular biology deals with the flow of genetic information within a biological system. It is often stated as "DNA makes RNA, and RNA makes protein", [1] although this is not its original meaning. It was first stated by Francis Crick in 1957, [2] [3] then published in 1958: [4] [5] The Central Dogma.
The polypeptide later folds into an active protein and performs its functions in the cell. The polypeptide can also start folding during protein synthesis. [1] The ribosome facilitates decoding by inducing the binding of complementary transfer RNA (tRNA) anticodon sequences to mRNA codons. The tRNAs carry specific amino acids that are chained ...
