Nucleic Acids

is the biomolecules responsible for the capability of the cell to produce exact replicas.

Nucleotides

are building blocks of nucleic acids

mRNA

Carries genetic code or information from the DNA template

tRNA

temporary carriers of amino acids, bringing the appropriate amino acids to the ribosome based on the messenger RNA (mRNA) nucleotide sequence

rRNA

structural components of ribosomes

B-DNA

Right-handed. Most abundant form

Z-DNA

Least abundant form. Left-handed

James Watson and Francis Crick

Elucidated based on X-ray crystallography image of the DNA by Rosalind Franklin and Maurice Wilkins

Replication

DNA directed DNA synthesis

Unzipping/Helicase

opens or unwinds the DNA double helix

Enzyme Primace

anneals a primer

DNA Polimerades

add complimentary nucleotides to the elongating DNA strand

DNA Lygase

joins discontinued strand

Topoisomerase

removes tangle

Transcription

DNA directed RNA synthesis

Translation

RNA to protein

Point

change in 1 or more nucleotides

Transitional

purine to purine

Transversional

purine to pyrimidine

Silent

Codon containing the changed base codes for the SAME amino acid (di napapalitan)

Missense

codon containing for DIFFERENT amino aicd. (Napapalitan)

Nonsense

stop codon

Frameshift

Insert or Delete 1 or more nucleotides in the sequence

Insertion mutation

add

Deletion mutation

delete
