Signal Sequences: 1)A signal sequence is made of: a. Nucleotides b. Amino acids c. Lipids d. Carbohydrates 2)All protein synthesis starts on ribosomes that are located in the . 3)If a molecule lacks a signal sequence it will end up in the 4)Proteins with a nuclear localization sequence (NLS) are generated on ribosomes located in the . 5)Proteins with a mitochondrial signal sequence are generated in ribosomes located in the .

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

on the planet jupiter, the acceleration due to gravity is approximately 26 m s2 , roughly 2.7 times the acceleration due
