If a section of DNA that was transcribe has the sequence:
A – T – C
What would be the corresponding:
a)codon on mRNA
b)anticodon on tRNA
I have a finish reading a chapter in my biology book, but I am still not sure how to answer this question. Can someone smart help me out here?

DNA is composed of 4 bases, A, C, T, G.
When DNA is transcribed into RNA, instead of T (thymine), U (uracil) is substituted at the equivalent position.
Thus, your answer to (a) would be GAU.
(b) the anticodon would be the reverse complement of that sequence.
the answer is AUC

When DNA is transcribed, Thymine becomes Uracil when you make it into RNA. Then you just copy the base to its complementary base.
Uracil to Adenine
Cytosine to Guanine
So for a, it should be U-A-G.
I dont think i have learned about anticodon yets. Or i just wasnt listening well.

Here's a hint:
Adenosine is opposite to Thymine on DNA and RNA
Cytosine is opposite to Guanine on DNA
Cytosine is opposite to Uracil on RNA

a)mRNA: U-A-G
b)tRNA: A-U-C
