Question

brainly, 200 points I will give you the question to get the other 100 points

A gene has the base sequence that starts with gac tga cga tta.what would be the complementary dna strand formed from this DNA?

i already know this question It would be ctg act gct aat. please tell me if im wrong

What would be the mRNA base sequence formed from this DNA sequence?

Use the codon table below to find the first three amino acids in the protein formed from this gene.

The gene has a mutation and is changed to the sequence below.
GAC GGA CGA TTA
What kind of mutation is this?

What is the new mRNA strand produced by this mutated gene?

Does this mutation affect the protein produced? Explain.

Answer 1

1) ctg act gct aat (you are correct)

2) GAC UGA CGA UUA
* remember for mRNA, a pairs with u

3) Aspartic Acid (Asp), Arginine (Arg), Leucine (Leu)

4) substitution (t changed to g)

Explanation: from GAC TGA CGA TTA
to GAC GGA CGA TTA

5) new mRNA strand: CUG CCU GCU AAU

6) yes, because the amino acids changed, which will code for different proteins.


Hope that helped! And your teacher did a really bad job forming this question, like how there is no starting codon and (no clarity) you don’t know which DNA sequences to use.
