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.
