Briefly explain the differences between each strand in the way
that they were made (include the name of any specific pieces
involved). - ANSWER -the leading strand is replicated 5' to 3'
and goes thru the process without stopping, the lagging strand
has to be made in fragments called Okazaki fragments, becasue
the template strand is in the 3' to 5' direction and in order to be
replicated in the 5' to 3' direction short sections have to be
replicated in opposite direction and then pieced together
How many different amino acids are there? - ANSWER -20
How many possible 3-base codon combinations are there? -
ANSWER -64
What is a ribosome made of? - ANSWER -protiens and few
molecules of rRNA
What is on the bottom of a tRNA? - ANSWER -anticodon
What is located on the top of a tRNA? - ANSWER -animo acid
,How is a mRNA made? (What is the template structure) -
ANSWER -mRNA is made from a template strand of DNA; it's
bases are complementary to the DNA template strand
After the completion of translation, what can be said about the
gene's status? -
ANSWER -it is
expressed
What is the ribosomes role in translation? - ANSWER -it reads
the mRNA and
attaches the amino acids together to form a
polypeptide chain
What is the role of mRNA in translation? - ANSWER -it has
the codons that
code for amino
acids
What is the role of tRNA in translation? - ANSWER -it brings
the appropriate
amino acid to the
ribosome
What direction is the mRNA translated? - ANSWER -5' to 3'
What is the DNA sequence at the beginning of a gene? -
ANSWER -TATA
,What is the ending sequence of a gene? - ANSWER -poly A tail
Explain the sentence -"DNA is GC rich." - ANSWER -the large
portion of the
DNA bases is
GC
What is the "Centra Dogma" theory of genetics? - ANSWER -
DNA indirectly
codes for protiens;
DNA>RNA>protein
What is the start codon of a mRNA? - ANSWER -AUG
What are the 3 stop condons of mRNA? - ANSWER -UAA, UGA,
UAG
How are genes physically located on a chromosome? -
ANSWER -linear order
What is a codon? - ANSWER -set of 3 bases
How can genetic linkages be broken? - ANSWER -crossing over
Explain what a desirable linkage is. - ANSWER -two
desirable traits are
inherited
together
, What is the relationship between protwins and enzymes
(explain each and how
they relate to each other)? - ANSWER -an enzyme is a
specialized protien that
acts as a catalyst to biochemical reactions; proteins are
responsible for most
metabolic
reactions
What is a typical protein made of (number and how many)? -
ANSWER -1-4
chains of polypeptides that are made from chains of
multiple amino acids
Compare genes that are tightly linked to genes that are not
tightly linked. - ANSWER -genes that are tightly linked are more
likely to be inherited together, genes that are not tightly linked
could get separated by crossing over
If 2 genes are 84.1 cM apart, what are their recombination
frequencies? -
ANSWER -
84.1%
What is transcription? - ANSWER -a strand of mRNA being
made from a
template strand of
DNA
