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

Short answer

a. TTTTTT

b. CCCCCC

c. TCAGGTCCA

d. GACATATGCAAT

Step-by-step solution

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
