The reason for why a double-strand break in a DNA double helix cannot be repaired by a cell has to be explained. Concept Introduction: DNA and its nitrogen bases: • DNA is the abbreviation term of “ D eoxyribo n ucleic A cid”. It is a complex molecule found in all living things. • The primary function of DNA is to store and transmit genetic information. • A base is nitrogen containing heterocyclic compound which is found in DNA • There are mainly four nitrogen bases in DNA which are listed as follows: 1. Adenine 2. Guanine 3. Cytosine 4. Thymine Complementary bases: • Adenine is the complementary base of Thymine • Cytosine is the complementary base of Guanine. • In DNA, Adenine always makes a double bond with thymine ( A = T ) and cytosine always makes triple bond with guanine ( G ≡ C )

Interpretation Introduction

Interpretation:

The reason for why a double-strand break in a DNA double helix cannot be repaired by a cell has to be explained.

Concept Introduction:

DNA and its nitrogen bases:

• DNA is the abbreviation term of “Deoxyribonucleic Acid”. It is a complex molecule found in all living things.

• The primary function of DNA is to store and transmit genetic information.

• A base is nitrogen containing heterocyclic compound which is found in DNA

• There are mainly four nitrogen bases in DNA which are listed as follows:

1. Adenine

2. Guanine

3. Cytosine

4. Thymine

Complementary bases:

• Adenine is the complementary base of Thymine

• Cytosine is the complementary base of Guanine.

• In DNA, Adenine always makes a double bond with thymine (A=T) and cytosine always makes triple bond with guanine (G≡C)

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of NOCI tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it.
