Question

Essay Question (8 points) Answer should be approximately 1 to 2 paragraphs and use the relevant biochemical vocabulary to provide an answer. Transcription produces an mRNA transcript by copying a coding segment of DNA. The image shows three different strands A GCT GA C CTAGC GGA CA A 5 3" A GCUGACCUAGCGGACA A 5 (a) Identify which strand is the mRNA transcript, which is the template strand and which one is the coding strand. (b) Explain the differences between template and coding strands. (c) Explain the outcome in protein synthesis if the template and coding strands switched roles.

Explanation / Answer

Ans..a...

Strand C is the mRNA transcript as because it is not paired that means it must have been formed by the transcription of the given double stranded strand.

Strand b is tht template strand because mRNA is complementary to this strand

Strand a is the coding strand.coding strand is a misnomer as it doesn't code fof anything.

Ans..b... template strand code for.the mRNA

Coding strand code for nothing

Template strand is in 3 to 5 direction

Coding strand is in 5 to 3 direction

Base pair of mRNA are similar to the coding strand and are complementary to template strand

Ans...c...if the switch role then base pairs are according to new template strand so codons will be different so different amino acids will be formed which further form diffrent protein.
