DNA/RNA/Codon Practice

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What does the term 'replicate' mean in the context of DNA?

Back

In the context of DNA, 'replicate' means to copy.

Front

How many nitrogenous bases are present in DNA?

Back

DNA has four nitrogenous bases.

Front

What are the four nitrogenous bases found in DNA?

Back

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

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What amino acid does the codon CCU code for?

Back

The codon CCU codes for the amino acid Proline.

Front

In DNA, which base pairs with adenine (A)?

Back

In DNA, thymine (T) pairs with adenine (A).

Front

In DNA, which base pairs with guanine (G)?

Back

In DNA, cytosine (C) pairs with guanine (G).

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a template for protein synthesis, carrying the genetic information from DNA to the ribosome.

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.
