DNA & Protein Synthesis

Front

What determines the code, or information, of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What makes up the rungs (steps) of a DNA ladder?

Back

Nitrogen bases.

Front

Which type of RNA carries the message for how to make protein?

Back

mRNA (messenger RNA).

Front

What is the complementary mRNA sequence to the DNA strand: AACTGAA?

Back

UUGACUU.

Front

What best describes a DNA molecule?

Back

Double helix.

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 the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during protein synthesis.

Front

What is transcription in the context of protein synthesis?

Back

The process of copying a segment of DNA into mRNA.

Front

What is translation in the context of protein synthesis?

Back

The process of decoding mRNA to synthesize proteins.
