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.
![The image is a diagram related to the topic of DNA replication, titled "Power Notes" and from section 8.3.
### General Description:
There is a space provided for a general description of the DNA replication process.
### Diagram Details:
The diagram is centered on a DNA double helix structure, which is partially unwound. The diagram is labeled with various numbers corresponding to steps and structures in the replication process.
#### Process (Left Side):
There are four numbered boxes (1 to 4) left blank for describing the steps involved in the DNA replication process.
- **1.**
- **2.**
- **3.**
- **4.**
At the bottom, there's an "End result" oval shape left blank, which likely refers to the goal or outcome of the replication process.
#### Identify the Structures (Right Side):
The right side of the diagram includes labels pointing to specific parts of the DNA structure. These parts are left blank for identification.
- **1.**
- **2.**
- **3.**
- **4.**
### Visual Elements:
The diagram includes arrows indicating the direction of replication or interaction between the structures, highlighting key moments in the replication process. Additionally, several smaller components, which appear to represent enzymes or other molecules, interact with the DNA.
### Graphs or Diagrams Explanation:
The main element is a simplified graphic of a DNA double helix being unwound, with visual indicators for labeling processes and structures involved in DNA replication.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4544c423-9ef5-4f1a-aedf-f0473ee49d75%2F3620161e-4f42-4bcb-895d-70aba7dc1985%2F4ai27rk_processed.png&w=3840&q=75)
