Protein synthesis and cell division Flashcards
What problems are as a result of protein deficiency?
poor healing
liver damage
anaemia
reduced resistance to infection
weight loss
what does C,G,T and A stand for
Cytosine
Guanine
Thymine
Adenine
Where does transcription occur?
nucleus
What are the three types of RNA
Messenger RNA
Ribosomal RNA
Transfer RNA
What do you need to catalyse transcription of DNA?
RNA Polymerase
What is not apart of the sequence of RNA?
Thymine - uracil instead
What are the promoter and terminator sequence made from?
nucleotides
What organelle do we need to carry out translation?
Ribosomes
Ribosomes- what does the small unit have a binding site for?
mRNA
Ribosomes- what does the large unit have two binding sites for
tRNA
what is cell division important for?
repair
what can occur if cell division goes wrong?
cancer
in the cell cycle what is the non-dividing phase called?
interphase
in the cell cycle what is the cell division phase known as?
Mitosis PMAT
what occurs in prophase?
chromatin fibres condense forming chromatids
nuclear membrane disappears
centrioles start to migrate to opposite ends of cell
chromatid become attached to spindle fibres
