The following is the base sequence of an exon portion of a template strand of a DNA molecule: 5' GCC-ATT-CGA-ACT 3' a. What is the base sequence of the hnRNA strand synthesized from the DNA template strand? 3' 5' b. What is the base sequence of the MRNA strand synthesized from the hnRNA strand? 3' 5' c. What codons are present in the mRNA strand produced from the DNA template strand? d. What tRNA molecule anticodons are needed to interact with the codons present in the mRNA strand produced from the template DNA strand?
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.

![## Codon Table and tRNA Anticodon Questions
### Codon Table
The image presents a codon table with four primary sections, each defined by the first letter of the codon (A or G) listed vertically on the left side. The third letter is vertically listed on the right side (U, C, A, G). Each box within the table corresponds to one specific amino acid, specified by a three-letter code. These can be broken down as follows:
- **AUG**: Methionine (Met) [Initiation codon]
- **AAU, AAC**: Asparagine (Asn)
- **AAA, AAG**: Lysine (Lys)
- **AGU, AGC**: Serine (Ser)
- **AGA, AGG**: Arginine (Arg)
- **GUU, GUC, GUA, GUG**: Valine (Val)
- **GCU, GCC, GCA, GCG**: Alanine (Ala)
- **GAU, GAC**: Aspartic acid (Asp)
- **GAA, GAG**: Glutamic acid (Glu)
- **GGU, GGC, GGA, GGG**: Glycine (Gly)
### Questions
**(a) What amino acid will a tRNA be carrying if its anticodon is GGG?**
- Enter its 3-letter code: ___
**(b) What amino acid will a tRNA be carrying if its anticodon is UCC?**
- Enter its 3-letter code: ___
**(c) What amino acid will a tRNA be carrying if its anticodon is UAU?**
- Enter its 3-letter code: ___
To find answers, match the anticodon with the complementary codon in the table and identify the associated amino acid. Remember that the anticodon will pair with the codon in an antiparallel fashion (A-U, G-C).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc61a5b44-8a97-4e5a-b99c-8b446b273729%2F472ebcb3-7f8b-4433-83c1-dda92aeaa249%2Fe12x0v_processed.png&w=3840&q=75)
