Nexia biotechnologies spliced spider genes into the cells of lactating

Options

A. Cow
B. Sheep
C. Goat
D. Buffalo

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about Nexia Biotechnologies, which spliced spider genes into the cells of a lactating animal. We need to identify which animal it is from the given options: cow, sheep, goat, or buffalo.

2. **Identifying the Product**: Nexia Biotechnologies is known for creating a product called BioSteel, which is a high-strength fiber material. This material is derived from a recombinant spider silk-like protein.

3. **Source of the Protein**: The recombinant spider silk-like protein is extracted from the milk of transgenic goats. This indicates that the spider genes were inserted into the genetic material of goats.

4. **Gene Source**: The genes that were spliced into the goats are derived from a species of spider known as Nephila clavipes. These genes encode for the spider silk-like protein.

5. **Conclusion**: Since the spider genes were spliced into the cells of lactating goats, the correct answer to the question is "goat."

**Final Answer**: Goat
