If the warm, rising air was carrying enough water vapor, those clouds can grow into rainclouds.
 
        
             
        
        
        
Answer:
Transcription and DNA replication are cellular processes in which chromosomes must be decondensed.  
Explanation:
In transcription, the transcription factors need to interact with promoter sequences and for this purpose they require DNA accessibility. Similarly, the DNA replication is another cellular process that also need accessibility for binding DNA polymerases
