Organisation of Prokaryotic cells and Eukaryotic cells, do Prokaryotic cells have a nucleus ? |
The Answer - No |
|
The 6 ways linear chromosomes are packaged |
DANA , Nucleotide , Nucleotide with histones , More scaffolding , Chromosome |
|
What is in a nucleotide |
A sugar , a phosphate and a base |
|
Describe the base pairing rule for DNA |
A-T , C-G |
|
Why is DNA anti-parallel ? |
The anti-parallel structure of DNA is important in DNA replication. The nucleic acid sequence are complimentary and parallel but go in opposite directions . |
|
List three possible functions of non-coding DNA sequences. |
Regulation , Protection and Transcription |
|
In Eukaryotes is DNA circular or linear ? |
Linear |
|
In Prokaryotic is the DNA linear or circular ? |
Circular |
|
Do prokaryotic cells have plasmids ? |
Yes |
|
What is a prokaryotic cell? |
Unicellular organism that lacks a membrane bound nucleus, a mitochondria and any other membrane bound organelle . |
|
An example of a Prokaryotic cell ? |
Bacteria |
|
Example of a Eukaryotic cell ? |
Animal cell , plant cell and fungi |
|
Do both Prokaryotic cells and Eukaryotic cells have ribosomes ? |
Yes |
|
Do both Prokaryotic cells and Eukaryotic cells have a mitochondria? |
No only Eukaryotic cells do |
|
Shape of DNA is described as.... |
Double helix |
|
Do Eukaryotic cells have plasmids ? |
Present in some yeasts ; absent in animal and plant cells. |
|
In the packaging on DNA in Eukaryotic cells |
-DNA is wound around histone (their job is to package DNA into structural units called nucleosomes) proteins to form nucleosomes -the chromatin fibre is founded along a protein scaffold. -The nucleosomes coil and stack into chromatin fibre -the folded chromatin fibre is further folded and condenses into a chromosome - Carbon one = the carbon the base attaches to . |
