The following represent deoxyribonucleotide sequences in the template strand of DNA: Sequence 1: 5′-CTTTTTTGCCAT-3′ Sequence 2: 5′-ACATCAATAACT-3′ Sequence 3: 5′-TACAAGGGTTCT-3′ (a) For each strand, determine the mRNA sequence that would be derived from transcription. (b) Using Figure 12–7, determine the amino acid sequence that is encoded by these mRNAs. (c) For Sequence 1, what is the sequence of the partner 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.
The following represent deoxyribonucleotide sequences in the template strand of DNA:
Sequence 1: 5′-CTTTTTTGCCAT-3′
Sequence 2: 5′-ACATCAATAACT-3′
Sequence 3: 5′-TACAAGGGTTCT-3′
(a) For each strand, determine the mRNA sequence that would be derived from transcription.
(b) Using Figure 12–7, determine the amino acid sequence that is encoded by these mRNAs.
(c) For Sequence 1, what is the sequence of the partner DNA strand?
