(T/F) cell bio final
Centrifugation can be used to separate cellular components effectively.
True
Glycerol is a three-carbon compound that connects the fatty acid tails with the polar head group in phospholipids.(T/F)
True
Membrane components in the cell are made in the endoplasmic reticulum. (T/F)
True
NexGen sequencing is based on the principle of sequencing by synthesis
True
Restriction enzymes can be used to compare different genomes based on the produced pattern of DNA fragments.
True
The Golgi apparatus is made up of a series of membrane- enclosed compartments through which materials destined for secretion must pass. (T/F)
True
The hydroxyl groups on monosaccharides are reaction hotspots and can be replaced by other functional groups to produce derivatives of the original sugar.(T/F)
True
A disaccharide consists of a sugar covalently linked to another molecule such as an amino acid or a nucleotide.(T/F)
False
After protein separation by SDS/PAGE each band on the gel represents only one protein.
False
Centrifugation is an outdated technology and has been replaced by other methods. (T/F)
False
Centrifugation only be used to separate large objects, but small particles like microsomes and ribosomes cannot be separated. (T/F)
False
Isoelectric focusing of proteins separates by size.
False
Lysosomes are small organelles where fatty acid synthesis occurs.(T/F)
False
MicroArray analysis used to detect alternative splice variants
False
PCR can only be used to identify transcripts but cannot be used for quantification
False
Restriction enzymes cut DNA randomly.
False
Restriction enzymes recognize specific sequences are DNA and always cuts so that only blunt ends are produced.
False
SDS only binds to polar proteins.
False
Target sequences are added post-translational and remain on the protein throughout it's lifecycle.
False
The presence of double bonds in the hydrocarbon tail of a fatty acid does not greatly influence its structure.(T/F)
False
Western blotting is used to detect specific are in a DNA sequences after separation by gel electrophoresis.
False
