DNA, RNA

Front

What is the function of DNA?

Back

DNA carries genetic instructions for the development, functioning, growth, and reproduction of all known living organisms.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands that coil around each other.

Front

What is RNA?

Back

RNA (Ribonucleic Acid) is a molecule that plays a crucial role in coding, decoding, regulation, and expression of genes.

Front

What are the three types of RNA?

Back

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

Front

What is a codon?

Back

A codon is a sequence of three nucleotides on a strand of mRNA that codes for a specific amino acid.

Front

What amino acid is coded by AUG?

Back

Methionine.

Front

What is the role of tRNA?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during protein synthesis.

Front

What is the role of rRNA?

Back

rRNA (ribosomal RNA) makes up the major part of ribosomes and is essential for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.
