Study Notes
Biomolecules and Enzymes
- DNA and RNA are part of the nucleic acids biomolecule category.
- The specific molecule on which an enzyme acts is referred to as the substrate.
RNA Structure
- RNA contains ribose as its five-carbon sugar.
Genetic Code Conversion
- Molecules that participate in converting the genetic code into proteins and other gene products include mRNA, tRNA, and ribosomes.
Role of DNA Polymerase
- DNA polymerase is responsible for adding nucleotides to the growing DNA strand during DNA replication.
Gene Function
- A gene in a DNA molecule or chromosome functions as a blueprint for producing specific proteins.
DNA Replication Process
- After the separation of the two DNA strands during DNA replication, complementary nucleotides are added to each strand to form new strands.
Importance of DNA Duplication
- Ensuring that DNA molecules duplicate before cell division is crucial for maintaining genetic consistency across daughter cells.
Transcription Enzyme
- The primary enzyme involved in transcribing the genetic code from DNA to produce mRNA is RNA polymerase.
Gene Expression Regulation
- Genes that are only expressed when the gene products are needed are referred to as inducible genes.
Location of Transcription in Eukaryotes
- In eukaryotes, transcription occurs in the nucleus.
One Gene-One Polypeptide Hypothesis
- The hypothesis stating that one gene of a DNA molecule is used to make one molecule of mRNA is known as the one gene-one polypeptide hypothesis.
