Introduction:
DNA is a double-stranded helical molecule that carries genetic information in all living organisms. The length of a DNA molecule is determined by the number of nucleotide base pairs that it contains.

Answer:
The given double-stranded DNA molecule is 50 base pairs long. The length of this DNA molecule will be more than 3.4 nm, which is the distance between two adjacent nucleotides in the DNA molecule. The actual length of the DNA molecule will depend on various factors such as the degree of coiling and packing of the DNA molecule.

Explanation:
The length of a DNA molecule is typically measured in nanometers (nm). The distance between two adjacent nucleotides in a DNA molecule is approximately 0.34 nm. Therefore, the length of a DNA molecule can be calculated by multiplying the number of nucleotide base pairs by 0.34 nm.

In the case of the given double-stranded DNA molecule, which is 50 base pairs long, the length can be calculated as follows:
Length = 50 x 0.34 nm = 17 nm

However, this calculation only gives the length of the DNA molecule if it is stretched out in a straight line. In reality, DNA molecules are highly coiled and packed to fit into the nucleus of a cell. The degree of coiling and packing can vary depending on the organism and the cell type. In some cases, the DNA molecule may be tightly coiled and packed, resulting in a much shorter length than the calculated value. In other cases, the DNA molecule may be less tightly coiled and packed, resulting in a longer length than the calculated value.

Conclusion:
In conclusion, the length of a DNA molecule is determined by the number of nucleotide base pairs that it contains and can vary depending on the degree of coiling and packing. The length of a 50 base pair DNA molecule will be more than 3.4 nm but the actual length will depend on various factors.

OK distance between two consecutive base pair of dna molecule is 0.34 nm#therefore Total length of DNA molecules is (0.34×50)nm =1.70nm
