MRNA
The order of amino acids on a polypeptide chain is encoded by:
Has final say if a production batch may be released for sale or use?
Function of Quality Assurance (QA) personnel?
The 3D structure of DNA is revealed.
What contributed to biotechnology in the 1950's?
Agar
Solid media on which bacteria grow
R group
What part of an amino acid differs from one to the other?
Occurs when amino acid sequence is linked by hydrogen bonds.
What is secondary protein structure
Form tetra relevant bonds, highly stable/unstable, able to form short
and long chains
,properties of the carbon atom that make the diversity of carbon
compounds possible.
Unbranched
A polypeptide is an ___ chain of amino acids
Hydrophobic
Are lipids hydrophilic or hydrophobic?
Structural component of plant cell walls, Ex: Cellulose
Carbohydrate:
Structural component of cell membrane, Ex: Phospholipid
Lipid:
Catalyze biochemical reactions, Ex: Enzyme
Protein:
Store and transfer genetic information in the cell, Ex: RNA
Nucleic Acid:
Antiparallel
The nucleotide strands of DNA are oriented in opposite directions in
a structure that is described as
An enzyme that cuts DNA after recognizing a specific sequence of
DNA.
Restriction enzyme:
Form the phospholipid bilayer of the plasma membrane.
Phospholipid:
Identify and neutralize foreign objects such as bacteria and viruses.
Antibody:
,Rules over cell functions which include cell division, morphing of the
shape of the cells, cell mobility and other contractile
properties/Helps in muscle contraction
Actin/Myosin:
20
How many amino acids are there?
Enzymes lose function outside of a narrow pH range..
Why are enzyme solutions always prepared using a buffered solvent
at a specific pH?
Buffer solutions are used to keep pH levels constant in a number of
chemical reactions.
Why are enzymes necessary in living organisms?
Leads to increase in high energy collisions.
Why does the rate of a chemical reaction increase with increasing
temperature?
Concentration of reactants, heat, the presence of a catalyst
What affects rate of chemical reaction?
Converts energy into ATP; take place in mitochondria
Cellular respiration:
Cellular energy with oxygen
Aerobic respiration:
Cellular energy without oxygen
Anaerobic respiration:
Process where a single cell divides twice to produce four cells
containing half the original amount of genetic information (sex cells).
They go through mitosis.
, What is meiosis and what happens if it does not happen during
sex-cell development in plants?
Denature proteins and give them negative charge
What is the purpose of SDS when used in SDS electrophoresis?
Haploid
Diploid/Haploid: EGG/SPERM
Diploid
Diploid/Haploid: ZYGOTE
Diploid
Diploid/Haploid: EMBRYO
Diploid
Diploid/Haploid: PARENT PLANT
Haploid: One set of chromosomes; gametes
Diploid: Two sets of chromosomes; somatic cells
Zygote: 2 haploid gametes fuse during fertilization to form a diploid
cell (zygote)
Whats difference between diploid/haploid/zygote?
Same as parent; 46
After a mitotic division, how many chromosomes do daughter cells
have compared with the parent cell?
Alternative forms of a gene that arise by mutation and are found at
the same place on a chromosome.
Alleles:
Mitochondria
Most ATP in eukaryotic cells is produced in the:
