Identify the true statements about rna interference. select all the true statements.
a. mirna is cleaved by dicer enzyme complex
b. duplex rna (dsrna) can suppress the expression of a gene.
c. mirnas are short duplexes approximately 21 nucleotides long
d. mirnas suppress gene expression by interfering with transcription
e. rna interference can temporarily suppress the expression of a target genes
(i think a and c and e are true. i doubt that b is right because rna need to be single strand to be read, not sure about d)

Remember that:

a. Dicer cleaves pre-miRNA, wich is a dsRNA.

b. dsRNAs are not functional because RNA interference depends on the RNAi ability to pair with parts or the entire mRNA to be silenced.

c. Yes, they are short.

d. They supress gene expression after transcription.

e. Yes because translation of mRNA is neutralized.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

yes? sounds right, but you didn’t ask a question.
