and CORRECT DETAILED ANSWERS ALREADY GRADED
A+
Where are nonpolar amino acids found? - CORRECT ANSWER-often in the
interior of a folded protein
how to id nonpolar amino acids - CORRECT ANSWER-side chains consist mostly
of hydrogen and carbon
polar charged amino acids are - CORRECT ANSWER-hydrophilic
how to id polar amino acids - CORRECT ANSWER-have no more then 4:1 ratio
of Cto N/O/and/orS
Four levels of protein structure - CORRECT ANSWER-primary, secondary,
tertiary, quaternary
primary structure - CORRECT ANSWER-amino acid sequence
,T/F:the protein within the cell will be found in a linear state - CORRECT
ANSWER-f
how a protein is found in the cell - CORRECT ANSWER-compact 3D structure
(this folding begins translation)
reverse transcriptase - CORRECT ANSWER-RNA world able to make DNA from
RNA template
Benefits of having introns? - CORRECT ANSWER-Alternative splicing
ends of eukaryotic linear chromosomes are replicated by - CORRECT ANSWER-
telomerase (enzyme)
telomerase (enzyme) uses an________template - CORRECT ANSWER-RNA
DNA replication - CORRECT ANSWER-makes DNA copies that are transmitted
from cell to cell and from parent to offspring
,Chromosomal DNA stores information in units called - CORRECT ANSWER-
genes
Pribnow box - CORRECT ANSWER-the TATAAT sequence that is often found at
the -10 region of bacterial promoters
the closer the____________sequence the stronger the promoter - CORRECT
ANSWER-Consensus
consensus sequence - CORRECT ANSWER-the most commonly occurring bases
within a sequence element
consensus sequences apply to the - CORRECT ANSWER--35 and the -10 region
what four polypeptides does the RNA polymerase core enzymes consist of -
CORRECT ANSWER-a, a, B, B'
the fifth subunit RNA Polymerase is called the - CORRECT ANSWER-sigma
factor
, RNA Polymerase - CORRECT ANSWER-binds loosely to DNA and scans along
the DNA until sigma encounters a promotot and binds to it
difference between RNA and DNA Polymerase - CORRECT ANSWER-
RNA=double stranded DNA entering the enzyme(except primase used in DNA
replication)
DNA=single stranded DNA entering the enzyme
bacterial transcription is terminated using sometimes - CORRECT ANSWER-rho
protein
bacterial transcription can also be terminated using - CORRECT ANSWER-NusA
protein
T/F: there is very little space between genes in bacteria - CORRECT ANSWER-
true
Bacterial and eukaryotic RNA polymerases have the same: - CORRECT
ANSWER-general structure
