Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

Question

Transcribed Image Text:### Question 88
**How do DNA and RNA differ?**
- ○ DNA is double stranded while RNA is single stranded.
- ○ all statements are differences between DNA and RNA.
- ○ Thymine is present in DNA but not in RNA.
- ○ DNA has the sugar deoxyribose and Ribose is the sugar in RNA.
*Explanation:*
This question is designed to assess knowledge about the structural and functional differences between DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
1. **Double-Stranded vs. Single-Stranded:**
- DNA is typically double stranded, forming a double helix structure, while RNA is usually single stranded.
2. **Base Composition:**
- In DNA, the base thymine (T) pairs with adenine (A). In RNA, uracil (U) takes the place of thymine.
3. **Sugar Component:**
- DNA contains the sugar deoxyribose, whereas RNA contains the sugar ribose.
4. **Correct Answer:**
- The correct answer is likely, "all statements are differences between DNA and RNA," since each of the individual statements is true and differentiates DNA from RNA.
