Replication, Transcription and Translation

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA double helix, separating the two strands to allow for replication.

Front

Describe the structure of a DNA molecule.

Back

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

Front

Where does translation occur in a cell?

Back

Translation occurs at the ribosome, where the genetic code is translated into proteins.

Front

In double-stranded DNA, which base pairs with Adenine?

Back

Thymine pairs with Adenine in double-stranded DNA.

Front

How many amino acids are represented by the nucleotide sequence ATG GGA ACT CCA?

Back

The sequence codes for 4 amino acids.

Front

What is the function of RNA polymerase?

Back

RNA polymerase synthesizes RNA from a DNA template during the process of transcription.

Front

What is transcription?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

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 significance of the start codon AUG?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for the amino acid Methionine.
