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.
