DNA Replication Flashcards
nuclear membrane
it is doble and continuous with the endoplasmic reticulum . it contains pores on its walls
the nucleoplasm
nuclear sap which contains free nucleotide bases.
nucleolus
which manufactures and contains ribosomes RNA
the chromatin network
which contains DNA. the chromatin network later unwinds to form chromosomes
name 2 nuclear acids
DNA and RNA
what are nuclear acids made up of
made up of small units or monometers called nucleotides
what are nucleotides made up of
a nitrogenous base
a sugar potion deoxyribose in DNA, ribose in RNA
a phosphate potion
what is DNA within chloroplast called
chloroplastic DNA
what is nuclear DNA
the DNA within the nucleus is called nuclear DNA
what is extra nuclear DNA
small amounts of DNA are also found outside the nuclears
why is mitochondrial DNA important
IN helping us trace our ancestors.
what does nuclear DNA control
controls the synthesis manufactures of protein and it also controls synthesis of enzymes
what are enzymes
specialized proteins
what are the functions of enzymes
enzymes control all the metabolic activities within the cell e.g. cellular respiration
what can we summarize the first function of DNA
controls the structure and functioning of cells and thus the organism as a whole by controlling the manufacture of a proteine,including enzymes.
what is the function of the chloroplastic DNA and mtDNA
controls protein synthesis within these organelles themselves
what is the second function of DNA
nuclear DNA also transmits characteristics from parent to offspring
