Where do mutations occur?

Back

Mutations occur in DNA.

Front

Name of the scientist whose x-ray photographs of the DNA molecule provided the clues needed to solve the structure of DNA.

Back

Rosalind Franklin.

Front

Which of the following could be a DNA nucleotide?

Back

A DNA nucleotide consists of deoxyribose sugar, thymine, and a phosphate group.

Front

What is the role of DNA polymerase during replication?

Back

DNA polymerase is responsible for proofreading the addition of nucleotides and fixing any mistakes.

Front

During replication, which sequence of nucleotides would bond with the DNA sequence TATGA?

Back

The sequence that would bond is ATACT.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine, thymine, cytosine, and guanine.

Front

What is the function of RNA?

Back

RNA serves as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.
