Biology Exam 1 terms

-membrane that surround sthe cell and separates it from the outside/ selectively permeable

-genetic material of the cell/ stores instructions for making parts of the cell and new cells

-instructions to make parts of cells or new cells

• -copying the gene into a message molecule called RNA
• -occues in nucleus

• -creating the protein from the gene's plan via the RNA copy
• -occurs in cytoplasm

• -workbenches that put the proteins together from the amino acids building blocks.
• -translates nucleic code into protein code

• -all material inside plasma membrane and outside nucleus.
• -filled with proteins, lipids, nucleotides

-smallest units that retain all the properties of life.

-working machines

-membrane building blocks

-DNA building blocks

• - sum of all biochemical reactions that make life possible
• - mostly occurs in cytoplasm

• -single celled bacteria and archaea
• -have no nucleus*

• -prokaryotic
• -eukaryotic

• -found in eukaryotes
• -everything other than bacteria and archaea
• -have a nucleus*

prokaryotic

-contained within a nucleus

-not enclosed in a nucleus or other structure

• -much bigger than prokaryotic cells
• -contain organelles, parts in a cell
• -contain a cytoskeleton

• -network of protein structures that give shape and organization to eukaryotic cells
• -attached to organelles

• -largest organelle in the cell
• - 3 parts
• - has pores but DNA never leaves because it can't
• -stores DNA

• -nuclear envelop
• -chromatin
• -nucleolus

• -complex of proteins with DNA of the cell
• -arranged in chromosomes

-where ribosomes are put together
