Intro to Cell Bio
This is the difference between prokaryotes and eukaryotes.
What is the lack of a nucleus? (In prokaryotes)
This type of fatty acid contains double bonds.
What is an unsaturated fatty acid?
This strand is read by RNA polymerase.
What is the non-template strand?
Inactive ribosomal subunits are located in this part of the cell.
What is the cytosol?
These particles work to splice RNA by aiding in the formation of spliceosomes and lariats.
What are snRNPs?!
All living cells come from other cells, cells are the smallest units of life and all organisms are made of one or more cells is part of this theory.
What is cell theory?
This functional group on the 2nd carbon of a pentose ring differentiates RNA from DNA.
(What makes RNA different from DNA)
What is an OH group?
One of the most common promoter regions in eukaryotes.
What is the TATA box?
Translation begins when this binds to an mRNA attached to a small ribosomal subunit, then the large subunit joins to initiate the process.
What is initiatoer tRNA/Met-tRNA
(Formyl-Met tRNA in prokaryotes)
These enzymes phosphorylate target proteins.
What are protein kinases?
This domain of prokaryotes are known for being extremophiles.
What are archea/archebacteria?
Amino acid chains may fold into one of these shapes to form a secondary structure.
What are a-helices and B-pleated sheets?
A unit which binds to RNA polymerase in prokaryotes to initiate transcription.
What is the sigma factor?
This enzyme prepares tRNA by attaching the correct amino acid. There are 20 different kinds.
What is aminoacyl tRNA synthetase?
Enzyme activity may be slowed/stopped by these. (Be specific).
What are allosteric and competitive inhibitors?
This person first coined the term "cells"
These types of bonds are considered to be the strongest in biology.
What are covalent bonds?
(Most ionic compounds are water soluble)
RNA polymerase synthesizes RNA in this direction.
What is the 5'-3' direction?
This theory explains that the last base in a codon can vary without destructive results.
What is the Wobble Hypothesis?
This is produced as a by-product of anaerobic respiration in muscle cells.
What is lactic acid?
This theory states that mitochondria were prokaryotic organisms consumed by early eukaryotes.
What is the endosymbiont theory?
This type of glucose has 1,4-glycosidic bonds.
What is B-glucose?
This transcription factor carries TATA binding protein and is required to initiate transcription in eukaryotes.
What is TFIID?
New amino acids are added to this end of the amino acid chain.
What is the C-terminus?
This organelle is known as THE POWERHOUSE OF THE CELL.
What is the mitochondria?
