Frequently Asked Questions
What is DNA sequence analysis?
DNA sequence analysis involves examining the order of nucleotides (A, T, G, C) in a DNA molecule. It helps understand genetic information, identify mutations, and predict protein sequences.
Why is GC content important?
GC content affects DNA stability because G-C base pairs have three hydrogen bonds compared to A-T's two bonds. Higher GC content generally indicates more stable DNA and can influence gene expression and DNA melting temperature.
How does transcription work?
Transcription converts DNA to RNA by replacing thymine (T) with uracil (U) and creating a complementary strand. This RNA can then be used as a template for protein synthesis.
What is the genetic code?
The genetic code is the set of rules by which DNA/RNA sequences are translated into proteins. Each three-letter codon (triplet) of nucleotides corresponds to a specific amino acid or a stop signal.
How are mutations identified?
Mutations are identified by comparing DNA sequences to reference sequences. Changes can include substitutions (different base), insertions (added base), or deletions (removed base), which may affect protein structure and function.
Important Notes
- DNA uses A, T, G, C nucleotides
- A pairs with T, G pairs with C
- RNA uses U instead of T
- Codons are 3-nucleotide sequences
- Start codon is AUG
- Stop codons are UAA, UAG, UGA
