The Cell – Alberts
Questions And
Answers
How many species are there? - (correct answer) -Around 8.7 Million
Most living organisms have how many cells? - (correct answer) -Most are
single celled organisms
Others, such as ourselves, are multicellular organisms in which groups of
cells perform specialized functions and are linked by intricate systems of
communcation.
How many cells does a human body have? - (correct answer) -10¹³
How are human cells generated? - (correct answer) -The whole is
generated from cell division
What is the "vehicle" for hereditary information for organisms? - (correct
answer) -The cell, which carries the hereditary information that defines
the species.
And specified by this information, the cell includes machinery to gather
raw materials from the environment and to construct out of them a new
cell in its own image.
How long have living cells been evolving? - (correct answer) -3.5 Billion
years
Where do all living cell store their hereditary information? - (correct
answer) -In DNA.
, What is DNA's Structure? - (correct answer) -Double stranded molecules -
long unbranched paired polymer chains, called strands, twisted into a
double helix made from the same four monomers - A, T, C and G - and they
are strung together in long linear sequences that encodes the genetic
information, just as the sequence of 1s and 0s encode the information of a
computer file.
Parts of a nucleotide? - (correct answer) -sugar (dioxyribose) with a
phosphate group attached to it, and a nitrogen-containing base, which
may be either adenine, guanine, cytosine or thymine.
Each strands are liked via sugar-phosphate group linkages, creating a
polymer chain composed of repitive sugar-phosphate backbone with a
series of bases protruding from it.
Concept: A single isolated strand, can be, in principle added in any orgder,
because each links in the same way. - (correct answer) -Basically, A will
always go to T, C always to G and the phosphates will always link to the
sugar, etc.
What are the bond between nucleotides on opposide strands? - (correct
answer) -Weak hydrogen bonds - This allows the two DNA strands to be
pulled apart without breakage of their backbones.
Each strand can then serve as a template for the stnthesis of a fresh DNA
strand complementary to itself - a fresh copy, that is, of hereditary
information.
The bonds between nucleotides on individual strands? - (correct answer) -
Strong covalent bonds
DNA Replication - (correct answer) -The process by which a copy of DNA ia
made
What are the rates of cell replication in cells? - (correct answer) -They are
different and depend on the type of cellWith different controls to start it
or stop it, and different auxiliary molecules to help it along.
How does DNA polymerization work? - (correct answer) -DNA is the
information store, and templated polymerization is the way in which this
information is copied throughout the living world.
