Summary Introduction

To write:

The nucleotide sequence of RNA produced from the transcription of DNA with sequence CGATTACTTA.

Introduction:

A nucleotide is formed from three components “pentose sugar, a phosphate group, and nitrogenous bases”. Nucleic acids are complex molecules found in living organisms. They are formed from the interaction of many nucleotides. These are DNA and RNA. DNA stands for “deoxyribonucleic acid” and RNA stands for “ribonucleic acid”

Expert Solution & Answer

Explanation of Solution

The process of conversion of DNA into a form of RNA (mRNA) is termed as transcription. DNA and RNA contain the same type of nitrogenous bases. However, thymine is replaced by another nitrogenous base uracil (U) in RNA.

Therefore, the RNA transcript formed from DNA with sequence CGATTACTTA is GCUAAUGAAG.

Conclusion

GCUAAUGAAG is the nucleotide sequence of RNA produced from the transcription of DNA with sequence CGATTACTTA.
