Study Notes
DNA Structure and Replication
- DNA's backbone is formed by deoxyribose sugar and phosphate groups
- Nitrogen bases (adenine, thymine, cytosine, guanine) form the other half of the DNA structure
- Hydrogen bonds hold the two DNA strands together
- The sequence of bases determines traits
- DNA replication is when DNA copies itself
- Complementary base pairing occurs during replication (A-T, C-G)
Enzymes in DNA Replication
- Helicase unzips the DNA strand
- Primase guides DNA polymerase
- DNA polymerase adds nucleotides by matching complementary bases
- Ligase glues DNA fragments together
Protein Synthesis
- Transcription is the process of going from DNA to make mRNA. It occurs in the nucleus.
- When copying DNA to mRNA, bases are different. (A-U and C-G)
- Translation is creating a protein from mRNA and occurs at the ribosome
- mRNA carries the instructions from DNA to the ribosomes for protein synthesis
- Genes in DNA are used to make proteins
