Front

What is the complementary mRNA sequence for the DNA strand ATG TGA CAG?

Back

UAC ACU GUC

Front

Why does an inserted base in a DNA sequence cause the protein to not work?

Back

The inserted base causes the codons in the sequence to be incorrect for the desired protein.

Front

What is the blueprint for the production of mRNA within a cell?

Back

DNA

Front

How would you best describe a DNA molecule?

Back

Double helix.

Front

What determines the code of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogen base.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is transcription in the context of the central dogma?

Back

The process of copying a segment of DNA into mRNA.

Front

What is translation in the context of the central dogma?

Back

The process of decoding mRNA to synthesize proteins.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes facilitate the translation of mRNA into a polypeptide chain.
