1.5 DNA and Protein Synthesis

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand during replication.

Front

What two molecules make up the backbone of the DNA structure?

Back

The backbone of DNA is made up of deoxyribose sugar and phosphate.

Front

How do you determine the complementary DNA strand for 3' A A A T T T C 5'?

Back

The complementary strand would read 5' T T T A A A G 3'.

Front

What type of RNA carries amino acids to the ribosome?

Back

tRNA (transfer RNA) carries amino acids to the ribosome during protein synthesis.

Front

Which statement is true regarding RNA and DNA?

Back

RNA is single-stranded, while DNA is double-stranded.

Front

What is the function of mRNA in protein synthesis?

Back

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

Front

What is the difference between DNA and RNA in terms of sugar?

Back

DNA contains deoxyribose sugar, while RNA contains ribose sugar.

Front

What is the significance of the 5' and 3' ends of a DNA strand?

Back

The 5' and 3' ends indicate the directionality of the DNA strand, which is crucial for replication and transcription.

Front

What is the process of transcription?

Back

Transcription is the process of synthesizing RNA from a DNA template.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into a polypeptide chain.
