DNA and Protein Synthesis

Front

What is the role of hydrogen bonds in DNA?

Back

Hydrogen bonds hold the nitrogenous bases together, specifically between Adenine and Thymine, and between Guanine and Cytosine, stabilizing the DNA double helix structure.

Front

What is a stop codon?

Back

A stop codon is a nucleotide triplet within mRNA that signals the termination of translation, indicating that the ribosome should stop adding amino acids to the growing polypeptide chain.

Front

What enzyme unwinds the DNA double helix?

Back

Helicase is the enzyme that breaks the hydrogen bonds between the nitrogenous bases, unwinding the DNA double helix during replication.

Front

What are the steps or rungs of the DNA ladder?

Back

The steps or rungs of the DNA ladder are the nitrogen base pairs (Adenine-Thymine and Guanine-Cytosine) that connect the two strands of the DNA.

Front

Which base pairs with Adenine in DNA?

Back

Thymine pairs with Adenine in DNA.

Front

What is the function of RNA polymerase?

Back

RNA polymerase is the enzyme responsible for synthesizing RNA from a DNA template during the process of transcription.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other, with a sugar-phosphate backbone and nitrogenous bases in the center.

Front

What is transcription in protein synthesis?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence.

Front

What is translation in protein synthesis?

Back

Translation is the process by which ribosomes read mRNA sequences and synthesize proteins by linking amino acids together.
