DNA/RNA Review (Accel.)

Front

What is a triplet of mRNA called?

Back

A triplet of mRNA is called a codon.

Front

What type of bond joins nitrogenous bases?

Back

Nitrogenous bases are joined by hydrogen bonds.

Front

Which enzyme unzips the DNA for replication?

Back

The enzyme that unzips the DNA to prepare for replication is helicase.

Front

What does the anti-codon contain in relation to the codon?

Back

The anti-codon contains a sequence complementary to the codon.

Front

How many bases are in a codon?

Back

Codons contain 3 bases.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the role of RNA polymerase?

Back

RNA polymerase synthesizes RNA from a DNA template during transcription.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins from amino acids based on mRNA sequences.

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.
