DNA Structure

Front

What makes up the SIDES of a DNA ladder?

Back

The sides of a DNA ladder are made up of sugars and phosphates.

Front

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

Back

The rungs of a DNA ladder are made up of nitrogen bases.

Front

According to Chargaff's rule, Cytosine always pairs with which base?

Back

Cytosine always pairs with Guanine.

Front

What type of bond joins nitrogenous bases in DNA?

Back

Nitrogenous bases are joined by hydrogen bonds.

Front

What is the SHAPE of DNA?

Back

DNA has a double helix shape, resembling a twisted ladder.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are Adenine, Thymine, Cytosine, and Guanine.

Front

What is the function of DNA?

Back

DNA carries genetic information and instructions for the development and functioning of living organisms.

Front

What is the role of the sugar in the DNA structure?

Back

The sugar in DNA (deoxyribose) forms the backbone of the DNA strand along with phosphate groups.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure allows for the compact storage of genetic information and provides stability.
