Prokaryotes have chromosomes.
True.
Bacteria can have DNA in other places besides the chromosome.
True.
What is in the cytoplasm in prokaryotes?
Genetic material such as chromosomes and plasmids, Ribosomes and Storage bodies and inclusions.
Bacteria generally have a single large chromosome.
True
The chromosome found in bacteria is not bounded by a membrane.
True
What are plasmids?
A extrachromosomal circular DNA. It typically contains genes that are not necessary for the organism survival but which may be useful to it.
How can plasmids be transferred?
It can be transferred 'horizontally’
How can plasmids be used in science?
They can be used as vectors for transferring DNA in genetic engineering.
What is the function of Ribosomes?
They are used to construct proteins from messenger RNA.
What are ribosomes made of?
They are in two parts and made up of proteins and ribosomal RNA.
What are endospores primarily made for?
Survival.
Endospores are some of the toughest, most resistant life forms of all, partially due to the presence of dipicolinic acid in the spore coat.
True.
What Genera has endospores?
Bacillus and Clostridium
Persistence and resistance of endospores contribute to the pathogenicity of Bacillus and Clostridium based species.
True
In the presence of an attractants, what happens to runs and tumbles?
Run become longer and tumble become fewer.
In the presence of an repellant, what happens to runs and tumbles?
Runs become shorter and tumbles happen more often
In response to an attractant, a bacterium will increase the duration of its ______ relative to its ______
Runs/tumbles
Flagella and cilla in eukaryotes are the same in size and function as bacteria.
False.
What Eukaryotes have flagella and where are they located on them?
They are found on the ends of some protozoa and algae, at the end of them. typically found in pairs or singly and they are much larger than bacterial flagella.
What Eukaryotes have Cilla and where are they located on them?
Ciliates, a type of protozoan. They are shorter than flagella and they function like oars in order to move the cell.
