3)____________are non-functional genes that have a sequence similarity to a gene family
4) If incorrect splicing occurs due to RNA sequences that closely resemble a real splice site, it is called_____________ splice site selection??
5) The histones are highly acidic proteins that interact with positively charged DNA.
Group of answer choices---- True/False
6) With what protein does the double-stranded miRNA become associated? The RNA duplex then is disassembled and one of the single strands is incorporated into a RISC complex.
a)slicer b)riscin c)ribonuclease d)mincer e)an Argonaute protein
7) What appears to be the role of siRNA in destroying the target mRNA upon which it and its associated proteins act?
Group of answer choices
a)It activates the RISC complex ribonuclease.
b)It guides the RISC that cleaves the target mRNA to that target mRNA due to its complementarity to that molecule.
c)It stabilizes the target mRNA.
d)It destabilizes the target mRNA's binding to its associated proteins.
e)It cleaves the target mRNA.

Which of the following statements regarding the TATA binding protein (TBP) are true: Recognizes a sequence that is similar are identical to 5'TATAAA3' Ο Ο Ο All are correct. It is considered a universal transcription factor It is a part of TEIID protein complex It binds to a consensus sequence The backbone of a DNA molecule is made up of phosphate groups made up of sugars made up of alternating phosphate and sugar groups Made up of alternating sugars and...
As indicated in the image below, miRNAs usually have imperfect base pairing with their target mRNAs, which leads to translational inhibition (the RISC complex is large, and won't let ribosomes through). On the other hand, siRNAs produced from longer double stranded RNA molecules (e.g. viruses), usually show perfect binding to their target mRNAs, which leads to mRNA degradation by the RISC complex. In 100 words or fewer explain why these two types of inhibitory ncRNAs differ in their mode of...
please answer all 6 questions Question 27 3 pts TRBP is a protein important for the formation of the RISC complex.
