NAS2 EXAM LATEST UPDATED VERSION
The cell spends most of its life in
interphase
what type of solution is this cell in ?
hypertonic
enzyme unzips DNA like a zipper, creating two single strands of
DNA
helicase
builder enzyme that synthesizes new strands of DNA by adding
DNA nucleotides
DNA polymerase
Enzyme that joins or glues fragments of DNA together
Ligase
Enzyme that creates a starting point for DNA polymerase
primase
there are ________ amino acids coded by _________ codons
20; 64
, A triplet (3 bases) of mRNA is called a
codon
which type of passive transport is being shown in this image ?
Facilitated Diffusion
which is an enzyme filled organelle that breaks down waste in
the cell ?
lysosome
The model that describes the current understanding of the cell
(plasma) membrane structure is
fluid mosaic model
Which part of the cell cycle is considered interphase?
G1, G2, S
What phase is this in ?
Interphase
Which phase is this in?
Telephase
Interphase has 3 stages; G1, S, and G2. What happens during
synthesis?
The cell makes a copy of its DNA
