Meiosis reduces the chromosome number, starts out with 46, then 23, then 23 and then 46 again. because 23+23 is 46
Answer:
30 protein molecules per mRNA molecule
Explanation:
In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.
The warmer the star, the bluer it will appear. The cooler a star, the more red it will appear.
Proxima Centauri Red Dwarf Stars for example have significantly less heat, therefore their red color.
The "rungs" of the DNA strand are made up of nitrogenous bases.
The type of ion channels responsible for the depolarization phase of an action potential are Na+ (sodium)
channels. Sodium ions flow inward through the sodium channels and cause an
increase in the concentration of positively charged ions in the cell; this in
turn, leads to depolarization.
