Week 1
This is the correct base-pairing pattern in DNA.
What is A pairs with T and G pairs with C?
The end of a polypeptide chain where a free carboxyl group is located.
What is the C-terminus?
A bond between amino acids.
What is a peptide bond?
Human females have have _____ different chromosomes while human males have _____ .
What is 23 and 24?
The impermeable boundary between a cell and its environment, which consists of a phospholipid bilayer.
What is the plasma membrane?
The family of amino acids whose R-groups are primarily hydrophobic, causing them to often be buried in a protein's core.
What is Nonpolar?
Responsible for the folding of a protein
What are non covalent bonds?
A highly condensed form of chromatin that has the critical property of being able to self-propagate.
What is heterochromatin?
Genes in different species that originate from the same ancestral gene in the last common ancestor
What are orthologs?
Unlike the spherical, water-soluble globular proteins that are usually involved with enzymes and transport, this class of proteins is elongated, insoluble, and provides structural support.
What are Fibrous Proteins?
Random association of different protein domains that creates a new gene.
What is domain shuffling?
The process that eliminates mutations that interfere with important genetic functions from a population
What is purifying selection?
The enzyme responsible for copying DNA strands into complementary RNA sequences during the process of transcription.
What is RNA polymerase?
This term applies to an alpha helix with one face predominately composed of nonpolar residues and the opposite face predominately composed of polar residues.
What is Amphiphilic?
Link between SH groups of two cysteine side chains
What are disulfide bonds?
Long interspersed nuclear elements, short interspersed nuclear elements, long terminal repeat retrotransposons, and DNA transposons are 4 types of mobile pieces of DNA known as this
What are transposable elements?
Events that create extra gene copies in the genome which allows new functions to form gene families over time.
What are gene duplication events?
A protein interaction mechanism where the binding of a ligand to one site on a multi-subunit protein complex alters the shape and affinity of a different binding site on an adjacent subunit.
What is Allostery?
The prokaryotic mRNA elongation factor.
What is EF-Tu?
Name 3 sequences that are needed for a chromosome to function properly
What are telomeres, centromeres, and replication origins
