What are the components of DNA nucleotides?

Back

DNA nucleotides consist of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What is a codon?

Back

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

Front

What is nondisjunction?

Back

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division, leading to an abnormal number of chromosomes.

Front

What is the role of high heat in PCR?

Back

The high heat during PCR denatures DNA, separating the two strands to allow for replication.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, consisting of an amino group, a carboxyl group, and a unique side chain.

Front

What is the structure of DNA?

Back

DNA is a double helix formed by two strands of nucleotides twisted around each other, held together by hydrogen bonds between complementary bases.

Front

What is the function of RNA?

Back

RNA plays a crucial role in translating genetic information from DNA into proteins.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

What is the difference between DNA and RNA?

Back

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

Front

What is transcription?

Back

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