Unit 5: DNA/RNA/Proteins/Mutations

Front

What carries the DNA code to the ribosomes and is read in sets of three bases, called codons?

Back

mRNA (messenger RNA) carries the DNA code to the ribosomes for protein synthesis.

Front

What is the shape of DNA that is often compared to a twisted ladder?

Back

The shape of DNA is called a double helix.

Front

If the DNA sequence is ATCAGCGCTGGC, how many amino acids are coded for by this message?

Back

4 amino acids are coded for by the sequence.

Front

What is a section of DNA that codes for one particular protein called?

Back

A gene.

Front

What is the complementary strand of DNA for AATCATGGA?

Back

The complementary strand is TTAGTACCT.

Front

What are the building blocks of DNA?

Back

Nucleotides are the building blocks of DNA.

Front

What are the four nitrogen bases found in DNA?

Back

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

Front

What is the process by which DNA is copied to make mRNA called?

Back

Transcription.

Front

What is the role of tRNA in protein synthesis?

Back

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

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.
