What is the role of DNA in protein synthesis?

Back

DNA contains the genetic instructions for the development and function of living things, which are transcribed into mRNA and then translated into proteins.

Front

What is a codon?

Back

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

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) brings amino acids from the cytoplasm to the ribosomes during protein synthesis.

Front

What is the process of transcription?

Back

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

Front

Where does transcription take place in a cell?

Back

Transcription occurs in the nucleus of eukaryotic cells.

Front

What is the mRNA sequence for the DNA sequence ATA CCG?

Back

The mRNA sequence is UAU GGC.

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 are ribosomes made of?

Back

Ribosomes are made of ribosomal RNA (rRNA) and proteins.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes for protein synthesis.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides in tRNA that is complementary to a codon in mRNA.
