Answer:
Silencer
Explanation:
Silencers are the position and orientation free sequences that are present outside the protein-coding sequence of a gene. Silencers serve as a binding site for some transcriptional regulatory proteins that tend to inhibit gene expression. Binding of these "repressor" proteins to the silencers inhibits the gene expression.
The deletion of silencers from DNA would increase the rate of the gene expression as the inhibitory transcription regulatory proteins do not have binding sites to inhibit the gene expression. Therefore, the deletion of silencer sequences of the beta-globin gene would have caused the increased rate of its expression.
Answer:
The zonule, often referred to as the ciliary zonule, is the circumferential suspensory ligament that connects the lens of the eye to the ciliary body. The zonule is composed of an elaborate system of fibers that spans the gap between the lens and the adjacent nonpigmented ciliary epithelium (NPCE).
Explanation:
Answer: a, b, d, c, e, f
Explanation: The steps of Cas9 DNA recognition and cleavage goes in the following order lettered A, B, D, C, E and F. Cas9 recognizes and binds the sgRNA after which it binds to the double stranded DNA. It then unwinds and scans the dsDNA for its protospacer adjacent motif sequence (PAM) and on recognition the sgRNA binds to its complementary sequence followed by cleavage of the DNA at two points. That is how the double stranded break is created.
Answer:
Covalent bond
Explanation:
The answer is covalent bond
Answer: D
Explanation:
It is a parrallel circuit so it would not matter if one of the bulbs were not to work.
