Consider the two samples of DNA shown below. Single strands are shown for simplicity:
Sample #1
CAGTGATCTCGA ATTCGCTA GTA ACGTT
Sample #2
TCATGA ATTCCTGGA ATCAGCAAATGCA
If both samples are treated with a restriction enzyme (recognition sequence GAATTC) then indicate the number of fragments and the size of each fragment from each sample of DNA.
Sample # 1
# of fragments:_____
Sample # 2
# of fragments:_______
List fragment size in order: largest `to` smallest
Sample # 1
Sample # 2

Explanation

To solve the problem, we need to analyze both DNA samples and identify where the restriction enzyme (recognition sequence GAATTC) cuts each strand. Let's break down the steps:

### Step 1: Identify the recognition sequence in Sample #1
- Sample #1: CAGTGATCTCGA ATTCGCTA GTA ACGTT
- We need to find the sequence GAATTC in this sample.
- The sequence GAATTC is present in the DNA strand at the position "ATTCGCTA".

### Step 2: Cut the DNA at the recognition site in Sample #1
