Answer:
An RNA single-stranded molecule that is complementary to one of a gene's DNA strands, to be precise.
Explanation:
DNA sequences or segments code for proteins or molecules with defined functions, called genes.
Answer: It was obtained 8515 years ago
Explanation:
Expression for rate law for first order kinetics is given by:
![t=\frac{2.303}{k}\log\frac{a}{a-x}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B2.303%7D%7Bk%7D%5Clog%5Cfrac%7Ba%7D%7Ba-x%7D)
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) to find the rate constant:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
![t_{\frac{1}{2}}=\frac{0.693}{k}](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B0.693%7D%7Bk%7D)
![k=\frac{0.693}{5760}=0.00012years^{-1}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B0.693%7D%7B5760%7D%3D0.00012years%5E%7B-1%7D)
b) for completion of 36% of reaction
![t=\frac{2.303}{k}\log\frac{100}{36}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B2.303%7D%7Bk%7D%5Clog%5Cfrac%7B100%7D%7B36%7D)
![t=\frac{2.303}{0.00012}\log\frac{100}{36}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B2.303%7D%7B0.00012%7D%5Clog%5Cfrac%7B100%7D%7B36%7D)
t = 8515 years
The time was 8515 years.
The root cap??? I think not for sure though.
