What is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide is replaced by another in the DNA sequence.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more nucleotides are added to a DNA molecule, potentially altering the reading frame.

Front

What is the structure of ATP?

Back

ATP (Adenosine Triphosphate) consists of one adenine base, one ribose sugar, and three phosphate groups.

Front

How many different trinucleotides can be formed from one guanine, one uracil, and one adenine?

Back

6 different trinucleotides can be formed from one guanine, one uracil, and one adenine.

Front

Which base is a purine?

Back

A purine is a type of nitrogenous base that includes adenine (A) and guanine (G).

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more nucleotides are removed from a DNA sequence.

Front

What is a frameshift mutation?

Back

A frameshift mutation is caused by insertions or deletions that change the reading frame of the genetic code.

Front

What are the two types of nitrogenous bases?

Back

The two types of nitrogenous bases are purines (adenine and guanine) and pyrimidines (cytosine, thymine, and uracil).

Front

What is the role of ATP in cells?

Back

ATP serves as the primary energy carrier in cells, providing energy for various biochemical processes.

Front

What is a trinucleotide?

Back

A trinucleotide is a sequence of three nucleotides in DNA or RNA that can code for an amino acid.
