this requires energy to move substances across the cell membrane
What is active transport?
200
this has adenine, guanine, cytosine & thymine
What is DNA?
300
this organelle makes proteins & is found around the rough endoplasmic reticulum
What are the ribosomes?
300
mRNA carries the genetic message to the ribosomes, this type of RNA brings the appropriate amino acids.
What is tRNA?
300
the importance of mitosis
What is to replace damaged or old cells?
300
this does NOT require energy to move substances across the membrane
What is passive transport?
300
in this molecule, uracil replaces thymine
What is RNA?
400
this is the packaging and processing center for proteins
What is golgi body (apparatus)?
400
this process actually turns the genetic message into polypeptides
What is translation?
400
stage when the chromosomes line up in the middle
What is metaphase?
400
this is movement of a substance from a high concentration to a low concentration (move down the concentration gradient)
What is diffusion?
400
this process copies the DNA strand
What is replication?
500
these organelles help to protect the cell from the outside environment and is said to be "semi-permeable" because it will allow some things in & not others
What is cell (plasma) membrane?
500
these are linked by a peptide bond to make a protein
What are amino acids?
500
this phase is in addition to mitosis & is when the cytoplasm is actually divided
What is cytokinesis?
500
movement of water across a semipermable membrane without using energy
