Biology Final Exam Fall

Adenine pairs with this in RNA

This is the cell's delivery system

Two new nuclei form and the cytoplasm begins to pinch in

This type of cell has NO nuclear membrane

Turner Syndrome

The cell membrane separates into two cells; each with a nucleus and some organelles

Adenine pairs with this in DNA

What is released during cellular respiration?

Active transport is the movement of molecules from:

When atoms share electrons, it is this type of bond:

Cytosine always pairs with

Contain genetic information

When genetic information in copied

Movement of water across a semi-permeable membrane

Mitosis produces:

This type of cell has a nuclear membrane

The heterozygote is a blend of the two parent phenotypes

Chromosomes line up in the middle of the cell

Monomers of proteins are:

What is measured in an experiment

This is composed of a lipid bi-layer and protein channels

A mutation that affects nucleotide sequence; may or may not affect protein production

How a hypothesis is tested

tRNA brings the correct amino acid anticodon to the ribosome to create a protein chain

A mutation that affects gametes

The cell theory does NOT include:

The physical attributes of an organism

A non-sex chromosome

In chemical reactions, enzymes lower:

Store Energy

Enzyme splits DNA molecule, free nucleotides pair correctly, creating 2 identical DNA strands

This is an educated guess

A solution that has pH of 5.2 is:

Ribosome binds amino acids together to create a protein chain

This is the powerhouse of the cell

These two determined that cells are the basic unit of life

An electromagnetic attraction between two ions is this type of bond:

Determined that all cells come from pre-existing cells

Division of cells resulting in the creation of gametes

mRNA "reads" and copies the DNA

He was the first to see living cells under a microscope

This stores water or chemicals for later use

Made of only one cell

This is disposes of cell waste

An allele that is always expressed over another allele

A red (RR) flower is crossed with a white (WW) flower. All offspring are pink (RW). This is:

Osmosis is:

The variable changed in an experiment

This is responsible for assembling proteins

Regulate most cell activity

These two determined that all cells come from living cells

This is the knowledge gained from careful observation

An organism has the trait, but it is not expressed

In translation, the appropriate tRNA anticodon to pair with the mRNA CUA is:

Make up cell parts

A group of 3 nucleotide bases

This is responsible for controlling all cell activity

Energy is released from ATP when:

Two dominant traits are equally expressed

A trait carried on the sex chromosomes

Nuclear membrane disappears and chromosomes coil up into x-shape

Down Syndrome

Photosynthesis uses sunlight to convert carbon dioxide and water into:

These are used for cellular locomotion

A water molecule contains:

Movement of any particle from area of high concentration to area of low concentration

Meiosis produces:

Chromosomes are pulled apart and move to opposite sides of the cell
