Solution
- To make a template strand, we need to replace each base with its complementary base. In this case, the template strand would be 3’-----TACCCCGAGTCGCT-----5’.
To transcribe the template strand to mRNA, we need to replace each base with its complementary base, except for thymine (T) which is replaced with uracil (U). The mRNA strand would be 5’-----AUGGGGCUAGCGAC-----3’.
To translate the mRNA into a protein, we need to use the genetic code. Each set of three bases (codon) corresponds to an amino acid. Starting from the 5’ end, the codons in the mRNA strand would be AUG, GGG, CUA, GCG, AC. Using the genetic code, the corresponding amino acids would be methionine (Met), glycine (Gly), leucine (Leu), alanine (Ala), and threonine (Thr).
The protein would be represented as Met-Gly-Leu-Ala-Thr, with the amino terminal (N-terminus) at the methionine and the carboxyl terminal (C-terminus) at the threonine.
- The direction of transcription is indicated by the arrow, which is from 3’ to 5’. To transcribe the given sequence, we need to replace each base with its complementary base, except for thymine (T) which is replaced with uracil (U). The mRNA produced would be 5’-----GCGGCGACGCGC-----3’.
The correct answer is B. 5’-----GCGCGUCGCCGC-----3’.
- The base sequence of codons 57-58 in the cytochrome Beta-5 reductase gene is CAGCGC. To transcribe this gene, we need to replace each base with its complementary base, except for thymine (T) which is replaced with uracil (U). The mRNA produced would contain the sequence 5’-----GUCGCG-----3’.
The correct answer is E. GUCGCG.

The trait in the pedigree appears to be dominant because it is present in every generation. Dominant traits are expressed even if only one copy of the gene is inherited.
The trait appears to be autosomal because it is present in both males and females. Autosomal traits are located on non-sex chromosomes.
Examples of diseases that exhibit dominant inheritance include Huntington's disease and Marfan syndrome.
- A three-generation pedigree showing mitochondrial inheritance would have the trait passed down through the maternal lineage. The trait would be present in all offspring of affected mothers, regardless of their gender.
Examples of diseases that exhibit mitochondrial inheritance include Leber's hereditary optic neuropathy and mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS).
