GENETICS Flashcards
From nucleic acids to proteins
GENETICS
Biomolecules made up of nucleotide
Nucleic Acid
DNA
Deoxyribonucleic Acid
RNA
Ribonucleic Acid
The genetic material of the cell
Double helical structure
DNA
What does DNA do?
-Codes sequence of the amino acid
-Controls protein synthesis
-It influencea the trait and characteristics of an animal
Composition of DNA
Sugar - phosphate backbone
Sugar - deoxyribose
Phosphate group
Nucleobase of DNA
Adenine
Guanine
Cytosine
Thymine
3 main type of RNA
mRNA
tRNA
rRNA
Messenger/carries instructions for synthesizing protein
mRNA
Picks up amino acid and helps position the amino acids
tRNA
Along with proteins, makes up ribosome
rRNA
From DNA to proteins
Central Dogma
-Creation of new DNA from one to old template
-semiconservative
REPLICATION
Information from DNA to RNA
TRANSCRIPTION
