Taylor and her husband Tyler just had a baby at the hospital. They believe the hospital has switched their baby. Taylor is type

Natalija [7]

Answer:

The DNA of the baby shares the DNA of both father and mother, and hence a cross link between an O type mother (Taylor) and an AB type father (Tyler) will produce children with blood groups A and B. It will be impossible to give birth to a child with blood group O.

The crispr system involves the cas9 enzyme, which identifies specific nucleotides to be cut using a(n) ________ molecule as a gu

bonufazy [111]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.

But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.

Imagine that you've discovered a regulatory sequence thousands of base pairs away from the promoter and that when this sequence

Tresset [83]

Answer:

An Enhancer

Explanation:

Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.

According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.
