Answer:
By transfecting small activating RNAs
Explanation:
Small activating RNAs (saRNAs) are an emerging class of non-coding RNAs (ncRNAs) that are capable of activating gene expression at transcriptional level. The saRNAs are small double-stranded RNAs (dsRNAs) that bind to promoter sequences in order to activate the expression of target genes. These molecules are structurally similar to small interfering RNAs (siRNAs), i.e., they also have a size of 21 nucleotides and two overhang nucleotides at the 3' end of both strands.
Answer:
The similarities in the way barchan and hooked spit forms are:
First, they are formed from sediment or sand movement.
Second, this movement makes them have a peculiar curved form that provides them their major characteristic.
Explanation:
First of all, barchans are sand formations that are created after the accumulation of sand in a place is moved by the wind and provides them a curved form. However, they exist only out of the sea.
Second, hooked spits are formations that happen after sea movement displaces the sediment to create a curved structure that can only exist in the sea. These formations affect the strength and direction of the waves in the sea due to their curved form.
