Cells and DNA Structure and Function

Front

What are the building blocks of DNA?

Back

Nucleotides are the building blocks of DNA.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) carries amino acids to the ribosome and matches them to the mRNA codons during translation.

Front

What is the process of making mRNA from DNA called?

Back

Transcription is the process of making mRNA from DNA.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where translation occurs, synthesizing proteins by linking amino acids together.

Front

What is the difference between prokaryotic and eukaryotic cells regarding DNA?

Back

Both prokaryotic and eukaryotic cells contain DNA, but prokaryotic DNA is not enclosed in a nucleus.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

What is the start codon for protein synthesis?

Back

The start codon is AUG, which codes for the amino acid Methionine.

Front

What is the end result of transcription?

Back

The end result of transcription is the formation of a single-stranded mRNA molecule.

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 the complementary base pairing rule in DNA?

Back

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