To calculate the approximate length of a gene containing 250 DNA nucleotides in nanometers, you can multiply the length of one nucleotide by the number of nucleotides in the gene:
Length of one nucleotide = 3.3 × 10^-10 meters
Number of nucleotides in the gene = 250
Length of the gene = (3.3 × 10^-10 meters/nucleotide) * 250 nucleotides
Now, calculate the length:
Length of the gene = (3.3 × 10^-10 meters/nucleotide) * 250 nucleotides
Length of the gene = 8.25 × 10^-8 meters
To express this length in nanometers, you can convert meters to nanometers by multiplying by 10^9 since 1 meter = 10^9 nanometers:
Length of the gene in nanometers = (8.25 × 10^-8 meters) * (10^9 nanometers/meter)
Now, calculate the length in nanometers:
Length of the gene in nanometers = 8.25 × 10^1 nanometers
Length of the gene in nanometers = 82.5 nanometers
So, the approximate length of the gene containing 250 nucleotides is approximately 82.5 nanometers.
