Cells and DNA

Single cells grow and [blank_start]divide[blank_end] to form more cells in a process called the [blank_start]cell cycle[blank_end]. A [blank_start]young[blank_end] cell undergoes cell division which promotes cell growth. The cells can then either grow into more stem cells or develop into specialized cells which in turn develop into [blank_start]mature[blank_end] cells. [blank_start]Embryonic[blank_end] development causes many cells to [blank_start]lose[blank_end] the ability to divide as they develop into the tissues and organs that make up organisms. The cells that retain many embryonic properties are called [blank_start]adult[blank_end] stem cells.

Cell division produces embryonic [blank_start]stem[blank_end] [blank_start]cells[blank_end].

Check off all that apply to embryonic stem cells.

Which of the following are fundamental statements of cell theory?

Which part of the plasma membrane is involved in recognition of other cells?

How do animals use cholesterol?

Which cell organelle is responsible for the production of proteins to be exported from the cell?

By which method do prokaryotes reproduce? ANSWER: [blank_start]binary[blank_end] [blank_start]fission[blank_end]

Prokaryotes do not have a mitochondrion

Complete the following statement using the correct numbers. (Use numbers not words. Ex: 15 not fiveteen) Eukaryotes have [blank_start]80[blank_end]s ribosomes and Prokaryotes have [blank_start]70[blank_end]s ribosomes.

Which of the following is true for a ribosome?

An animal cell is placed in a hypotonic (very weak) sugar solution and therefore the cell will decrease in mass.

Osmosis is the movement of [blank_start]water[blank_end] Diffusion is the movement of [blank_start]liquids and gases[blank_end]

The smaller the size of a cell the less surface area to volume it has.

Which of the following does 'surface to volume ratio' determine?

Which of the following types of transport moves from a low concentration to a high concentration?

Decode the following DNA to mRNA DNA --> TAC CTC CGG TGG GTG CTT GTC TGT ATC mRNA->[blank_start]AUG[blank_end] [blank_start]GAG[blank_end] [blank_start]ACC[blank_end] [blank_start]ACC[blank_end] [blank_start]CAC[blank_end] [blank_start]GAA[blank_end] [blank_start]CAG[blank_end] [blank_start]ACA[blank_end] [blank_start]UAG[blank_end]

[blank_start]A[blank_end][blank_start]U[blank_end][blank_start]G[blank_end] is the start codon [blank_start]U[blank_end][blank_start]A[blank_end][blank_start]G[blank_end] is the end codon

Where does the first step of protein synthesis occur? ANSWER: [blank_start]Nucleus[blank_end]

The bases on tRNA are called...

Drag the function to the correct primase, polymerase, and ligase: - RNA primase; forms short lengths of [blank_start]RNA[blank_end] primer at intervals [blank_start]along the DNA strand[blank_end] - DNA polymerase III; [blank_start]forms[blank_end] short [blank_start]DNA[blank_end] strands called Okazaki Fragments[blank_start], starting from each RNA primer[blank_end] - DNA polymerase I; [blank_start]replaces[blank_end] the [blank_start]RNA primer[blank_end] at the start of each Okazaki Fragment with a [blank_start]DNA strand[blank_end] - ligase; [blank_start]joins the DNA strands together[blank_end]
