DNA and Its Structure Flashcard

Front

Who used X-ray diffraction to capture images of DNA?

Back

Rosalind Franklin was the scientist who used X-ray diffraction to capture images of DNA, which were crucial in understanding its structure.

Which nitrogenous base pairs with adenine (A) in DNA?

Back

Thymine (T) pairs with adenine (A) in DNA, forming a base pair that is essential for the structure of the DNA molecule.

Front

Where is DNA located in eukaryotic cells?

Back

In eukaryotic cells, DNA is located in the nucleus, which is a membrane-bound organelle.

Front

What is the process of DNA packaging?

Back

DNA packaging refers to the process of fitting DNA into dense compact forms, allowing it to fit within the cell nucleus.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, resembling a twisted ladder, with two strands running in opposite directions.

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 DNA in cells?

Back

DNA carries genetic information that is used for the growth, development, and functioning of living organisms.

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 replication in the context of DNA?

Back

Replication is the process by which DNA makes a copy of itself before cell division.
