Assume that the average protein in E.coli consists of a chain of 400 amino acids. Now, a single amino acid present in the protein requires a codon to code for it. A codon consists of 3 nucleotides. This shows that a protein of length 400 amino acids will require, 400 codons to code for it, that is, 1200 (3 x 400) nucleotides are required. We know that the length of the E.coli genome on average is 5 x 
base pairs.
1200 nucleotides = 1 protein
5 x nucleotides = X no. of proteins
X = 
= 4167
The answer is 4167 proteins.

Probably molecular biology. Scientists have been able to look at organisms and compare them visually for rather a long time, but only recently have we been able to sequence genomes and compare organisms at the molecular level.
Answer:
If Red blood cell is placed in a hypotonic solution, the water moves into the cell. The cell swells and become turgid.
Explanation:
This is a type of osmosis. here plasma membrane of RBC works as semipermeable(only solute can move) osmotic membrane.
We all know that, osmosis is a process where liquid moves across semipermeable membrane from less concentration gradient to high concentration gradient.
There are three types of solution in respect of the concentration of cell's cytoplasm. These are
- Hypotionic (when the solution is dilute than the conc. of cytoplasm). In this condition water moves into the cell and the cell become turgid. this is known as deplasmolysis
- Hypertonic ( when the solution is concentrated than cytoplasm), In this condition water moves out from the cell and the cell become flaccid. This is known as plasmolysis.
- Isotonic (when both the conc. of cell and solution are same). No osmosis takes place.
Answer:
Esto es cierto porque una célula se define como la unidad básica, estructural y funcional de todas las formas de vida. La célula podría ser simple o compleja y contiene la información más importante sobre el individuo conocido como su ácido nucleico. El DNA controla la composición genética y física del individuo, coordina su comportamiento y garantiza que se adapte a lo largo de su vida. Esto hace que la célula sea crucial para la vida de un individuo. Los atributos físicos en el individuo, como la altura y el color de la piel, son controlados por la célula, mientras que también controlan los atributos genéticos, como el genotipo y el grupo sanguíneo.
