# Dna Weight Calculator

Result:

The DNA Weight Calculator is a handy tool for scientists and researchers to determine the molecular weight of a given DNA sequence. DNA, the building block of life, is composed of four nucleotide bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Each of these bases has a specific molecular weight. This calculator simplifies the process of calculating the combined weight of these bases in a given DNA sequence.

Formula

The molecular weight of a DNA sequence is calculated by summing the individual weights of its constituent bases. The weights of the four bases are as follows:

• Thymine (T): 304.2 g/mol
• Guanine (G): 329.21 g/mol
• Cytosine (C): 289.18 g/mol

To calculate the weight of a DNA sequence, you add up the weights of all the bases within that sequence.

How to Use

Using the DNA Weight Calculator is simple:

1. Enter the DNA sequence in the input field. Use only capital letters (e.g., ATGC).
2. Click the "Calculate" button.
3. The calculator will display the molecular weight of the entered DNA sequence in grams per mole (g/mol).

Example

Let's say you have a DNA sequence: ATGCGTAC. Using the calculator, you can find its molecular weight:

• A: 313.21 g/mol
• T: 304.2 g/mol
• G: 329.21 g/mol
• C: 289.18 g/mol

Total weight = 313.21 + 304.2 + 329.21 + 289.18 + 329.21 + 289.18 + 304.2 + 313.21 = 2451.59 g/mol

The calculator will display: "Result: 2451.59 g/mol."

FAQs
