What is a DNA nucleotide?

Back

A DNA nucleotide is the basic building block of DNA, consisting of a deoxyribose sugar, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).

What is a nucleotide?

Back

A nucleotide is a structural unit of nucleic acids, composed of a sugar, a phosphate group, and a nitrogenous base.

Front

What sugar is found in DNA?

Back

Deoxyribose is the five-carbon sugar found in DNA.

Front

How does RNA differ from DNA?

Back

RNA is single-stranded, contains uracil instead of thymine, and has ribose as its sugar.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other.

Front

What is the role of nucleotides in DNA?

Back

Nucleotides serve as the building blocks of DNA, encoding genetic information.

Front

What are the nitrogenous bases in DNA?

Back

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

Front

What is the complementary base pairing in DNA?

Back

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

Front

What is the process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself, involving unwinding the double helix and synthesizing new complementary strands.

Front

What is the function of RNA?

Back

RNA plays a crucial role in protein synthesis, acting as a messenger between DNA and ribosomes.
