Question | Answer |
Structure contains nitrogenous basesA, G, C, U, pentose sugar, ribose, usually consists of single strand, can coil back on itself, forms hair-shaped structures with complementary base pairing and helical organization, base pairing rules A with U and G wit | RNA |
contains a nitrogenous base and pentose sugar | nucleoside |
are the three types of RNA that differ from each other in function, site of synthesis in eucaryotic cells, and structure | mRNA, tRNA, rRNA |
All genetic material of an organism | genome |
Genomes of bacteria consist of | Chromosomes |
Allow transfer of genes between cells | fertility factors |
Resistance to antibiotics or heavy metals | resistance factors |
For bacteriocin toxins to kill other bacteria | bacteriocin factors |
Provide functions involved in pathogenesis | virulence factors |
Single DNA molecule, No histones, Haploid(No dominance/recessiveness), Located in the nucleoid, 4,377 genes in E. coli
(1mm of DNA in 1μm of space) | Bacterial Chromosome |
It can be copied,It can be expressed,It can be changed,It can be repaired if damaged, and It can be recombined/exchanged are the five things that can happen to | genetic information |
usually exists as closed circular, supercoiled molecule associated with basic proteins | Procaryotic DNA |
Allows DNA to fit in the cell and Helps control access to DNA | supercoiling |
molecules responsible for supercoiling and relaxing DNA,Ex. Gyrase | Topoisomerases |
linear molecules,associated with histones,coiled into repeating units called nucleosomes | eukaryotic DNA |
Within each cell genetic information flows from | DNA to RNA to protein |
This flow of information is | unidirectional and irreversible |
Conversion of DNA encoded information to RNA is called | transcription |
Conversion of information from mRNA to protein is called | translation |
Nucleotide sequence in DNA dictates the end product (protein) synthesis-called | genetic code |
