Question

Complete this exercise and answer the questions that follow. You will use the DNA strand (A G C A A T C C G T C T T G G) from Exercise 8 on p. 48 of your lab manual to make the protein for which it codes. Follow steps 1-6 on pp. 50-51 of your lab manual for this exercise. What is the amino acid sequence for the mRNA strand that you drew in step 6

Answer 1

Answer:

Amino acid sequence:

Serine (Ser)- Leucine (Leu)- Glycine (Gly)- Arginine (Arg)- Threonine (The)

Explanation:

This question is related to gene expression, which involves the transcription of DNA sequence into mRNA, and the subsequent translation of mRNA into amino acid sequence (protein).

- The transcription of a DNA sequence into mRNA is based on complementary base pairing rule i.e. A-T, G-C. Based on this pairing rule, the DNA sequence (AGC AAT CCG TCT TGG) will be transcribed into UCG UUA GGC AGA ACC.

- Using the genetic code which contains codons that encode amino acids, the mRNA sequence (UCG UUA GGC AGA ACC) will be translated into the amino acid sequence as follows: Serine (Ser)- Leucine (Leu)- Glycine (Gly)- Arginine (Arg)- Threonine (The).
