Nucleic Acids, Proteins, and DNA Manipulation

Front

What are nucleic acids?

Back

Nucleic acids are information molecules that encode instructions for the synthesis of proteins. They include DNA and the three main forms of RNA: mRNA, rRNA, and tRNA.

Front

What is the genetic code?

Back

The genetic code is a universal triplet code that is degenerate. It involves steps in gene expression, including transcription, RNA processing in eukaryotic cells, and translation by ribosomes.

Front

What is the structure of genes?

Back

Genes consist of exons, introns, and promoter and operator regions.

Front

What is gene regulation?

Back

Gene regulation involves processes like the prokaryotic trp operon, which is a simplified example of a regulatory process.

Front

What are amino acids?

Back

Amino acids are the monomers of a polypeptide chain, leading to hierarchical levels of structure that form a functional protein.

Front

What are proteins?

Back

Proteins are a diverse group of molecules that make up an organism’s proteome, including enzymes that act as catalysts in biochemical pathways.

Front

What is the role of the rough endoplasmic reticulum and Golgi apparatus?

Back

The rough endoplasmic reticulum, Golgi apparatus, and associated vesicles are involved in the export of proteins from a cell via the protein secretory pathway.

Front

How are enzymes used to manipulate DNA?

Back

Enzymes like polymerase synthesize DNA, ligase joins DNA, and endonucleases cut DNA.

Front

What is CRISPR-Cas9?

Back

CRISPR-Cas9 is a function in bacteria used for editing an organism’s genome.

Front

What is the polymerase chain reaction (PCR)?

Back

PCR is a technique used to amplify DNA.
