Intro to DNA structure

Front

Where do prokaryotic cells store DNA?

Back

In the cytoplasm.

Front

Which 2 molecules form the sides (backbone) of the DNA ladder?

Back

Deoxyribose (sugar) and phosphate.

Front

Who was the scientist who used X-rays to 'take a picture' of DNA?

Back

Rosalind Franklin.

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

Who are Watson and Crick?

Back

Watson and Crick are the scientists who proposed the double helix structure of DNA using Rosalind Franklin's X-ray images.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, resembling a twisted ladder.

Front

What are nitrogenous bases?

Back

Nitrogenous bases are the building blocks of DNA and include adenine, thymine, cytosine, and guanine.

Front

What is the role of deoxyribose in DNA?

Back

Deoxyribose is the sugar component of DNA nucleotides, forming part of the backbone.

Front

What is the function of DNA?

Back

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

Front

What is a hydrogen bond in DNA?

Back

Hydrogen bonds are weak attractions between nitrogenous bases that hold the two strands of DNA together.
