Question

directions: type your answer in the box. you may use numerals or words. dna replication involves producing new copies of dna molecules. how many individual dna strands exist after one molecule of dna has been replicated?

Explanation:

Step1: Recall DNA structure

A DNA molecule is double - stranded.

Step2: Understand replication process

During replication, the two strands separate and new complementary strands are synthesized. So, 1 double - stranded DNA molecule gives 2 double - stranded DNA molecules after replication.

Step3: Calculate number of strands

Since each double - stranded DNA molecule has 2 strands, 2 double - stranded DNA molecules have $2\times2 = 4$ strands.

Answer:

4
