DNA /PROTEIN SYNTHESIS

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix.

Front

What is the second step of gene expression/protein synthesis?

Back

The second step is called translation.

Front

What does DNA stand for?

Back

DNA stands for Deoxyribonucleic acid.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What does each codon in mRNA specify?

Back

Each codon in mRNA specifies a particular amino acid.

Front

What are nucleotides made of?

Back

Nucleotides are made of a sugar, a phosphate group, and a nitrogenous base.

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

How do the nitrogenous bases pair in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.
