UCI Bio 93 (Trio) Final Exam Review Questions
With 100% Verified Solutions
Refers to the assimilation of external DNA into the cell. (griffith
experiment) - ANSWER Bacterial Transformation
genetic material could be transferred between dead bacteria and
living bacteria (transformation principle)
- when heat killed S cell and living R cells were mized, the mouse
died - ANSWER Griffith's experiment
The process in which DNA is transcribed into mRNA. Occurs in
the nucleus. The three steps include: initiation, elongation, and
termination. - ANSWER Transcription
Promoter sequence to ease initiation which contains A and T
nucleotides because A and T only have 2 hydrogen bonds. -
ANSWER TATA Box
The strand of mRNA that is transcribed in a continuous stand
from DNA. - ANSWER Leading Strand
The strand of mRNA that requires a series of primers which
results in small Okazaki fragments. - ANSWER Lagging Stand
The direction in which DNA elongated - ANSWER 5' to 3'
2 hydrogen bonds. - ANSWER A and T
3 hydrogen bonds. - ANSWER C and G
,Acts as glue to join Okazaki Fragments. - ANSWER DNA Ligase
Short fragments of mRNA as it is transcribed from the lagging
strand. - ANSWER Okazaki Fragments
Cuts out the primers in the mRNA sequence. - ANSWER DNA
polymerase I
adds nucleotides to the 3' end, - ANSWER DNA polymerase III
Used during RNA splicing. Cuts out introns and joins exons. -
ANSWER Splicesomes
The modification of pre-mRNA to mRNA by adding a guanine cap
to the 5' end and a poly-A tail to the 3' end. Occurs in the nucleus.
This ensures the mRNA will not denature and facilitates the
mRNA bonding to the ribosome. - ANSWER RNA Process
The process in which the codons on mRNA are bonded to the
anticodon, creating a polypeptide. Uses energy found within GTP.
5' to 3'. - ANSWER Translation
The organelle that produces polypeptides. Contains a small
subunit and a large subunit which has a E, P, and an A site. -
ANSWER Ribosomes
The "A" site of the ribosome is the location in which the anticodon
from the tRNA is bonded to the codon from mRNA. - ANSWER
Aminoacyl-tRNA Binding Site
, The "P" site of the ribosome is the location in which the tRNA
leaves its associated amino acid to continue the polypeptide
chain. - ANSWER Peptidyl-tRNA Binding Site
The "E" site of the ribosome is the location in which the tRNA
exits the ribosome. - ANSWER tRNA Exit Site
The direction which the template DNA strand is read - ANSWER
3' to 5'
The genes within DNA. - ANSWER Genotype
The genes that are expressed from DNA. - ANSWER Phenotype
A series of multiple ribosomes working together to simultaneously
translate a mRNA sequence to very efficiently
produce polypeptides. - ANSWER Polyribosomes
Modifies polypeptide chains after they are produces by the
ribosomes. - ANSWER Golgi Apparatus
Cell division in somatic cells and results in two genetically
identical daughter cells. Reproduction in single cell amoeba.
Tissue renewal, growth, and development in multicellular
organisms. Has 5 sub-phases: Prophase, Prometaphase,
Metaphase, Anaphase, Telophase (PPMAT). - ANSWER Mitosis
The phase a cell spends majority of its life in. Prepares for
Mitosis by going through G1, S, and G2 phases. - ANSWER
Interphase
