Question

Which of the following sequences includes a clear 8 base pair palindrome? O5' -- CCGATCGATCCC -- 3' O 5' -- CTGGGGTTTTGG -- 3' O 5' -- CCGGGGAAAATT -- 3' 5' -- CTGATCCTAGCT -- 3' 05' -- AAAACCAACCAA -- 3' Question 13 (1 point) A normal 8-base restriction site starts with CGAT. What are the next four base pairs? O ATCG O TAGC OGCTA o CGAT

Answer 1

QUESTION 12

Remember that a palindrome sequence is the nucleotide sequence that can be read forward or reverse in the same way. As you can see, in option A, if you read in direction 5’ to 3’ and 3’ to 5’, the sequence will be the same. So, the correct answer is 5’CCGATCGATCCC-3’

QUESTION 13

In this case, you need to choose the complementary strand of the sequence but in the reverse direction. CGAT - ATCG

So, to correct answer is ATCG
