Given Question:
Can prokaryotes exchange genes with each other?
Answer: <u>True</u>
Explanation:
By the process of conjugation, their DNA is <u>transferred</u> from one prokaryote to another by means of a pilus, which brings the organisms into contact with one another. The DNA transferred can be in the form of a plasmid or as a hybrid, containing both plasmid and chromosomal DNA.
Answer:
D.) repressor DNA-binding site mutation
Explanation:
lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".
The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.
This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.
Answer:
The answer to your question is ACUCTTCUGGUCCCAACA
Explanation:
Base sequence
TGAGAAGACCAGGGTTGT
Nitrogenous bases change from DNA to RNA
DNA RNA
Adenine Uracil
Thymine Adenine
Guanine Cytosine
Cytosine Guanine
Then from left to right, the new sequence the RNA is
ACUCTTCUGGUCCCAACA
The answer is False
Hope this help :)
