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
![**Understanding mRNA and Amino Acids**
This image represents a handwritten question related to molecular biology and genetics. Below is the transcription of the text that will help you understand the educational content:
---
**DNA to Protein Synthesis: Decoding mRNA Sequences**
**mRNA Sequence:**
```
GAC UAU GCG GGA GGU AAG CCA UGA
```
**Question:**
What is the amino acid that would result from this mRNA sequence?
---
**Explanation:**
Messenger RNA (mRNA) is a type of RNA that conveys genetic information from DNA to the ribosome, where it specifies the amino acid sequence of the protein products of gene expression. The mRNA sequence is read in sets of three nucleotides, known as codons, each codon corresponds to a specific amino acid.
To determine the amino acid sequence encoded by the given mRNA, we use the genetic code, which translates codons into amino acids.
The mRNA sequence provided is:
```
GAC UAU GCG GGA GGU AAG CCA UGA
```
We will now decode each codon:
1. **GAC** - Aspartic Acid (Asp)
2. **UAU** - Tyrosine (Tyr)
3. **GCG** - Alanine (Ala)
4. **GGA** - Glycine (Gly)
5. **GGU** - Glycine (Gly)
6. **AAG** - Lysine (Lys)
7. **CCA** - Proline (Pro)
8. **UGA** - Stop Codon (ends translation)
**Resulting Amino Acid Sequence:**
Asp - Tyr - Ala - Gly - Gly - Lys - Pro
The last codon, UGA, is a stop codon which signals the end of translation and does not code for an amino acid.
This specific mRNA sequence translates into a chain of amino acids that constitutes part of a protein.
**Conclusion:**
This exercise helps in understanding the translation process and how genetic information is converted into functional proteins. Knowing how to decode mRNA sequences is fundamental in the fields of genetics and molecular biology.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb9adcd2a-782c-4aec-98d2-41735c0afa7a%2Ff31d1a67-494d-4128-b29f-943b2ea82e6c%2Fo1hi19t.jpeg&w=3840&q=75)
