Cell Structure Quotes

There are many cells you could look at forever in 3D.

You'd need a very specialized electron microscope to get down to the level to actually see a single strand of DNA.

Protoplasm, simple or nucleated, is the formal basis of all life. It is the clay of the potter: which, bake it and paint it as hewill, remains clay, separated by artifice, and not by nature from the commonest brick or sun-dried clod.

I like biology a lot.

I became aware of the very complex internal organization in a cell from the basic science classes, and it made me think about how all that could work. It seemed like a great mystery, especially how organelles in the cell can be arranged in three dimensions, and how thousands of proteins could find their way to the right location in the cells.

Until 1930 or thereabout biologists [using microscopes], in the situation of Astronomers and Astrophysicists, were permitted to see the objects of their interest, but not to touch them; the cell was as distant from us, as the stars and galaxies were from them.

Although a biologist, I must confess I do not understand how life came about... I consider that life only starts at the level of a functional cell. The most primitive cells may require at least several hundred different specific biological macro-molecules. How such already quite complex structures may have come together, remains a mystery to me. The possibility of the existence of a Creator, of God, represents to me a satisfactory solution to this problem.

In the early 1950s, during the near avalanche of discoveries, rediscoveries, and redefinitions of subcellular components made possible by electron microscopy, those prospecting in this newly opened field were faced with the problem of what to do with their newly acquired wealth.

Epigenetics doesn't change the genetic code, it changes how that's read. Perfectly normal genes can result in cancer or death. Vice-versa, in the right environment, mutant genes won't be expressed. Genes are equivalent to blueprints; epigenetics is the contractor. They change the assembly, the structure.

A cell is regarded as the true biological atom.

A cell is a complex structure, with its investing membrane, nucleus, and nucleolus.

We are seeing the cells of plants and animals more and more clearly as chemical factories, where the various products are manufactured in separate workshops.

A living cell requires energy not only for all its functions, but also for the maintenance of its structure.

Quantum physics has found that there is no empty space in the human cell, but it is a teeming, electric-magnet ic field of possibility or potential

Every cell in our body is primarily water. But the water doesn't just sit in the cell, it moves through it in a very organized way. The process occurs rapidly in tissues that have these aquaporins or water channels.

We finally understand in general terms how a cell is organized, how its specialized organs function in a well integrated manner to insure its survival and replication.

Small bodies, about half a micron in diameter, and later referred to under the name of 'mitochondria' were detected under the light microscope as early as 1894.

There are over 7,000 different types of proteins in typical eukaryotic cells; the total number depends on the cell class and function.

I was driven completely by a desire to understand how cells worked.

Like Honeycrisp, SweeTango has much larger cells than other apples, and when you bite into it, the cells shatter rather than cleaving along the cell walls, as is the case with most popular apples. The bursting of the cells fills your mouth with juice. Chunks of SweeTango snap off in your mouth with a loud cracking sound.

If you salt a chicken the day before cooking, it starts to break down the cell structure of the meat and allows it to take on more flavor and actually helps it to stay more moist. Same goes for a steak, a pork chop. A lot of people brine; we preseason.

Life needs a membrane to contain itself so it can replicate and mutate.

Proteins are the machinery of living tissue that builds the structures and carries out the chemical reactions necessary for life.

The genome was once thought to be just the blueprint for a living organism, like a combination of the architect's plan for a building and the builder's list of supplies. It specified the parts, the building blocks, and, somehow, the design of the whole, the way in which they are to be put together.

If you wanted to dissect the structure of living cells, genetic analysis was an extremely powerful method, so my interest turned to that.
