Q. 17.27 - 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. A A A A A A

b. GGGGGG

c. AGTCCAGGT

d. CTGTATACGTTA

Step-by-Step Solution

Answer

a. TTTTTT

b. CCCCCC

c. TCAGGTCCA

d. GACATATGCAAT

Part (a) Step 1: Given Information

The base sequence is- A A A A A A 

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 A A A A A A 

The base sequence in a complementary DNA segment is T T T T T T 

Part (b) Step 1: Given Information

The base sequence is GGGGGG  

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 GGGGGG 

The base sequence in a complementary DNA segment is CCCCCC 

Part (c) Step 1: Given Information

The base sequence is AGTCCAGGT 

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 AGTCCAGGT 

The base sequence in a complementary DNA segment is TCAGGTCCA 

Part (d) Step 1: Given Information

The base sequence is CTGTATACGTTA 

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 CTGTATACGTTA  

The base sequence in a complementary DNA segment is GACATATGCAAT
