The auricle (pinna) is the visible portion of the outer ear.
Answer:
A. CRISPR sequences in bacteria resemble those from bacteriophage and plasmid DNA. (The CRISPR sequences are derived from previously invading bacteriophages and pladmids.)
B. For reverse genetic studies, CRISPR /CAS can be used to replace wild type alleles with mutant alleles which can knock out the function of target genes. (CAS 9 introduces double strand break (DSB) in the target sequence which is then repaired by non homologous end joining (NHEJ). NHEJ causes deletion, insertion or frame shift mutation leading to knock out of the target genes.)
C. CRISPR is a bacterial sequence in the bacterial chromosome. ( The sequences are derived from bacteriophages that had infected the bacteria defore.)
D. The guide RNA guides CAS to specific DNA sequences. ( The guide RNA directs CAS nuclease to the target sequences for editing.)
E. The CRISPR/CAS system was discovered in bacteria, and it's natural function is the equivalent of an immune system in bacteria for remembering viral infections and for attacking viral DNA in future infections. (The CRISPR/CAS system provides acquired immunity to bacteria.)

The process is Meiosis. The 4 daughter cells are then known as haploids.
Answer:
The answer is D.
Explanation:
The scientific theory is a statement or explanation that is given for a natural occurance of an event which can be observed, tried repeatedly to verify it's results and turned into a theory from a hypothesis.
The option D given in the question on the scientific theory is not correct because theories are not accepted as explanations for natural events and they are also not accepted without experiments that yield the same results repeatedly.
The statements given in options A, B, C and E can be regarded true with respect to the scientific theory.
