Q.17.28 - An Introduction to General, Organic, and Biological Chemistry

Question

Write the base sequence in a complementary DNA segment if each original segment has the following base sequence:

a. T T T T T T

b. CCCCCCCCC

c. ATGGCA

d. ATATGCGCTAAA

Step-by-Step Solution

Answer

a. AAAAAA

b. GGGGGGGGG

c. TACCGT

d. TATACGCGATTT

Part (a) Step 1: Given Information

The base sequence is- T T T T T T 

Part (a) Step 2: Explanation

Complementary bases can attach to one another. Adenine (A) can attach to Thymine (T) and Guanine (G) bonds just to Cytosine (C). Hence we have the complementary bases - A-T and G-C.

For the following base sequence T T T T T T 

The base sequence in a complementary DNA segment is AAAAAA 

Part (b) Step 1: Given Information

The base sequence is CCCCCCCCC 

Part (b) Step 2: Explanation

Complementary bases can attach to one another. Adenine (A) can attach to Thymine (T) and Guanine (G) bonds just to Cytosine (C). Hence we have the complementary bases - A-T and G-C.
For the following base sequence CCCCCCCCC 

The base sequence in a complementary DNA segment is GGGGGGGGG 

Part (c) Step 1: Given Information

The base sequence is ATGGCA 

Part (c) Step 2: Explanation

Complementary bases can attach to one another. Adenine (A) can attach to Thymine (T) and Guanine (G) bonds just to Cytosine (C). Hence we have the complementary bases - A-T and G-C.
For the following base sequence ATGGCA 

The base sequence in a complementary DNA segment is TACCGT 

Part (d) Step 1: Given Information

The base sequence is TATACGCGATTT 

Part (d) Step 2: Explanation

Complementary bases can attach to one another. Adenine (A) can attach to Thymine (T) and Guanine (G) bonds just to Cytosine (C). Hence we have the complementary bases - A-T and G-C.
For the following base sequence TATACGCGATTT 

The base sequence in a complementary DNA segment is TATACGCGATTT
