DNA and RNA Structure

Front

What is the structure of DNA?

Back

DNA is a double helix formed by two strands of nucleotides twisted around each other, held together by hydrogen bonds between complementary bases (adenine-thymine and guanine-cytosine).

Front

What are the three types of RNA?

Back

The three types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

What is the primary function of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the primary function of tRNA?

Back

tRNA brings amino acids to the ribosome during protein synthesis, matching them to the coded message in mRNA.

Front

What is the primary function of rRNA?

Back

rRNA is a structural component of ribosomes, facilitating the assembly of amino acids into proteins.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids (DNA and RNA), consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the nitrogenous bases in DNA?

Back

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

Front

What are the nitrogenous bases in RNA?

Back

The nitrogenous bases in RNA are adenine (A), uracil (U), guanine (G), and cytosine (C).

Front

How do DNA and RNA differ in terms of sugar?

Back

DNA contains deoxyribose sugar, while RNA contains ribose sugar.

Front

What is the role of DNA in cells?

Back

DNA stores and transmits genetic information necessary for the growth, development, and functioning of living organisms.
