If the sequence of the 5'-3' strand is AATGCTAC, then the complementary sequence has the following sequence: a. 3'-AATGCTAC-5' b. 3'-CATCGTAA-5' c. 3'-TTACGATG-5' d. 3'-GTAGCATT-5'

Short Answer

Expert verified

Option c is correct.

Step by step solution

01

Step 1. Introduction

There are two types of nitrogenous bases in a nucleic acid that is pyrimidines and purines. Adenine is complementary to thymine and Guanine is complementary to cytosine.

02

Step 2. Explanation of the correct option

Option c is correct because complementary of 5'-AATGCTAC-3' is 3′-TTACGATG-5′

03

Step 3. Explanation of the incorrect options

Option a is incorrect because complementary of 5'-AATGCTAC-3' is 3′-TTACGATG-5′

Option b is incorrect because complementary of 5'-AATGCTAC-3' is 3′-TTACGATG-5′

Option d is incorrect because complementary of 5'-AATGCTAC-3' is 3′-TTACGATG-5′

Which of the following is not a true statement comparing prokaryotic and eukaryotic DNA replication? a. Both eukaryotic and prokaryotic DNA polymerases build off RNA primers made by primase. b. Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. c. DNA replication always occurs in the nucleus. d. Eukaryotic DNA replication involves more polymerases than prokaryotic replication.

Which prediction about the mutational load in the adult fruit flies is most likely to be correct? a. The adults with the DNA pol III mutation will have significantly more mutations than average. b. The adults with the DNA pol III mutation will have slightly more mutations than average. c. The adults with the DNA pol III mutation will have the same number of mutations as average. d. The adults with the DNA pol III mutation will have fewer mutations than average.
