Genetic Control Of Protein Synthesis, Cell Function And Cell Reproduction Flashcards
genes are composed of
deoxyribonucleic acid DNA
gene expression
the entire process from transcription of DNA in the nucleus to translation of RNA and the formation of proteins in the cytoplasm is referred to as gene expression
no. of genes present in each cell
approximately 30,000 genes
total no. of different proteins produced by different cell types
almost 100,000
function of enzymes
promote all oxidative reactions that supply energy to the cell along with synthesis of all cell chemicals like lipids, glycogen and adenosine triphosphate.
component involved in the formation of DNA
- deoxyribose sugar, 2. phosphoric acid 3. nitrogenous bases.
purines and pyrimidine
adenine, guanine and thymine, cytosine.
structure of DNA
phosphoric acid and deoxyribose sugar form to helical strands that make up the back bone and the nitrogenous base lie between the 2strands and connect them
nucleotide
combination of one molecule of phosphoric acid, deoxyribose sugar and one of the 4 nitrogenous base form an acidic nucleotide
types of nucleotides
deoxyadenylic , deoxythymidylic, deoxycytidylic, deoxyguanylic acid
