Answer:
The half-life (t1/2) is the time taken for the activity of a given amount of a radioactive substance to decay to half of its initial value. The mean lifetime (τ, “tau”) is the average lifetime of a radioactive particle before decay. The decay constant (λ, “lambda”) is the inverse of the mean lifetime
Answer:
It is required that the seed region of the processed dsRNA molecule bind to the mRNA of mex-3 in order to inhibit its translation
Explanation:
Double-stranded RNAs are small interfering non-coding RNAs (about 20 nucleotides in length) that, after processing, can bind by complementary base pairing to RNAs and thus inhibit protein translation by a mechanism referred to as 'RNA interference' (RNAi). The base pairing is not always perfect; however, the guide strands of dsRNAs can conserve their ability to inhibit the translation if the complementarity is enough good to match target RNA sequences. The critical region in the dsRNA that is required to bind target RNAs is known as seed region, and consists of 6 to 8 nucleotides in length.
the answer would be the third option: the cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
My positive answer is no because of the clothes and yes because of the mask but if it were a yes then astronauts wouldn’t need the space suit so the answer is NO
Answer:
d
Explanation:
that is an example of a point mutation. A point mutation is a mutation that causes only one nucleotide to change and in the example adenine changes to thymine
hope this helps (:
