Q. What is the storage of a genetic code?
Genetic Code. stored on one of the two strands of a DNA molecules as a linear, non-overlapping sequence of the nitrogenous bases Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). These are the “alphabet” of letters that are used to write the “code words”.
Q. Where is DNA hereditary stored?
chromosomes
Q. How many grams of DNA is in the human body?
Answer. DNA content of a typical human cell is about 6 x 10^-12 grams. Then all we need is the number of cells — as was mentioned above, estimates vary widely, but its between 1 and 100 trillion cells (1e12 to 100e12) for the human body. Thus we have between 6and 60 grams for an avg adult human.
Q. Which cells do not contain DNA?
Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA.
Q. Do bananas contain DNA?
If we could zoom in on a single, tiny cell, we could see an even teenier “container” inside called a nucleus. It holds a stringy substance called DNA, which is like a set of blueprints, or instructions. Just like us, banana plants have genes and DNA in their cells, and just like us, their DNA determines their traits.
Q. Why red blood cell have no nucleus?
Red blood cells have adapted this characteristic (no nucleus) for several reasons. It simply allows the red blood cell to have more hemoglobin. Therefore, it allows RBC to transfer more oxygen. Lack of nucleus in RBC also allows the cell to have an unique bi concave shape that helps with diffusion.
Q. Can a cell have more than one nucleus?
Multinucleate cells (multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm. For example, slime molds have a vegetative, multinucleate life stage called a plasmodium.
