Select from the dropdown lists to complete the text.

The ( Nucleolus, Nucleus, DNA ) is the ‘brain’ of a cell. This is surrounded by the ( Nucleus, Nucleolus, Nuclear Envelope ), which in turn is surrounded by the ( Nuclear Envelope, Rough ER, Nucleus ). The cisternae of the ( Rough Endoplasmic Reticulum, Smooth Endoplasmic Reticulum ) transport substances from one area of a cell to another. This organelle also contains many ( ribosomes, lysosomes, mitochondria ) which synthesise proteins from ( mRNA, DNA, Mitochondrial DNA ). The ( Smooth Endoplasmic Reticulum, Rough Endoplasmic Reticulum, Golgi Apparatus ) contains enzymes which catalyse reactions involved with lipid metabolism. The ( Golgi Apparatus, Smooth ER, Cytoskeleton ) modifies and packages substances into vesicles. ( Lysosomes, Ribosomes ) are full of hydrolytic enzymes which are used for the digestion of substances. ( Mitochondria, Mitochondrions, Vesicles ) produce ATP during ( aerobic respiration, Anaerobic Respiration ). They are thought to have been a foreign organism which was consumed by another single celled organism and underwent ( symbiosis, biosis, dibiosis ). ( An undulipodium, A tail, Cillia ) enables a cell to move (although the only human cell to have one is a spermatozoon) and ( cilia, Ciliums, Hairs ) can push substances past a cell. Both these structures contain ( cytoskeletons, muscles, microfibrils ) which allow them to move. ( Vacuoles, Leaves, Green Pigments ) are found in most plant cells. They are surrounded by membranes called ( tonoplasts, tonioplasts ). ( Chloroplasts, Cytoskeletons, Cell walls ) are also in plant cells. They are the site of ( photosynthesis, anaerobic respiration )

Question 5 of 5

1

Select all the processes that occur during DNA transcription.

Select one or more of the following:

An mRNA copy is made of the gene
mRNA leaves the nucleus through the nuclear pore
mRNA attaches to a ribosome
The ribosome synthesises the mRNA
The ribosome reads the base pairs of the mRNA and adds complementary base pairs, creating the substance
The substance travels to the Golgi Apparatus where it is packaged into a vesicle
A section of the Golgi Apparatus is pinched off into a vesicle
The vesicle travels to the plasma membrane where it fuses with the plasma membrane and exits the cell by exocytosis
DNA leaves the nucleus via a nuclear pore
