Study Notes
Flow of Genetic Information
- The flow of genetic information involves DNA, transcription to RNA, and translation to proteins.
- Transcription converts specific DNA segments into RNA.
- Ribosomes are the sites for protein synthesis, translating the mRNA into amino acid sequences.
Cancer Concepts
- Metastasis refers to the spread of cancer cells from the original site to distant body locations.
- A benign tumor is a mass of uncontrolled cell growth that remains localized.
- Carcinogens are agents that cause mutations leading to cancer development.
DNA and RNA Structures
- The key difference between DNA and RNA nucleotides is the base; RNA has uracil (U) instead of thymine (T).
- DNA contains the bases adenine (A), guanine (G), cytosine (C), and thymine (T); RNA has A, G, C, and uracil (U).
- RNA is single-stranded, while DNA is double-stranded.
Genetic Definitions
- A gene is a segment of DNA that codes for proteins or portions of proteins.
- A nucleotide consists of three components: a sugar, a phosphate, and a base.
- DNA provides the instructions to make proteins; RNA subsequently synthesizes proteins.
Nucleotide Sequences
- If the DNA template strand reads GCCATTAC, the corresponding mRNA sequence is CGGUAAUG.
- According to base pairing rules, if one DNA strand reads AGGCTTA, the complementary strand will read TCCGAAT.
Cancer Prevention and Treatment
- Cancer prevention strategies include maintaining a healthy diet and regular exercise.
- Cancer treatments include chemotherapy, radiation therapy, and surgical removal of tumors.
Basic DNA Knowledge
- DNA stands for deoxyribonucleic acid and is integral for genetic information transmission.
- Hydrogen bonds hold the two strands of DNA together.
Ribosomes and Protein Translation
- Ribosomes translate mRNA into proteins, facilitating the synthesis based on genetic instructions.
