### Sequence Data of SARS-CoV-2 Spike Protein

Scientists have sequenced SARS-CoV-2 genomes from various states to understand genetic variation. Table 1 provides sequence data for the spike protein gene from SARS-CoV-2 viruses collected in different states.

#### Table 1: SARS-CoV-2 Spike Protein Sequence Variations

| State      | 1059 | 3037 | 14408 | 18060 | 23403 | 25563 | 28144 | Number of Differences |
|------------|------|------|-------|-------|-------|-------|-------|-----------------------|
| Washington | C    | C    | C     | T     | A     | G     | C     | –                     |
| Utah       | C    | T    | T     | C     | G     | T     | T     |                       |
| Colorado   | C    | C    | C     | C     | A     | G     | T     |                       |
| Kansas     | C    | T    | T     | C     | G     | G     | T     |                       |
| California | T    | T    | T     | C     | G     | T     | T     |                       |

**Explanation:** 
- The table lists nucleotide sequences at different positions for samples from several states.
- The sequence from Washington acts as a reference.
- Nucleotides at specific positions show mutations that vary from the Washington sequence.
- The “Number of Differences” column is designed to note differences from the Washington sequence.

**Question 3:**  
Which of the following types of mutations is represented in Table 1?  
a. substitutions  
b. insertions  
c. deletions  

*Answer to Question 3:* The table primarily shows **substitutions**, where one nucleotide is replaced by another at specific positions.

Expert Solution
Introduction:

Mutations in the DNA happen at random and are not directed in any way to bring about a positive or negative change in the protein being coded by those segments of DNA.
