This DNA molecule is replicating - write a complimentary strand to this template TAC GGG CAG CAT AAA ATC​
Firdavs [7]

Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG

Explanation:

The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).

The mRNA directs specific bases to pair the existing base on the replicating DNA strand:

- Adenine (A) pairs only with Thymine (T)

- Guanine (G) pairs only with Cytosine (C)

So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC​, substitute each letter with its base pair.

Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG

Nuclear power has come under higher scrutiny in recent years. Which statement would make the strongest for the use of nuclear po
Tamiku [17]

The Answer is A) Nuclear power generates large amounts of power limited to projection of greenhouse gases.

I believe this is the answer. As per the reports in 1998, it has been calculated the emission of the greenhouse gas has reduced for nearly half due to the popularity in the use of nuclear power. Nuclear energy by far has the lowest impact on the environment since it does not releases any gases like carbon dioxide, methane which are largely responsible for greenhouse effect. There is no adverse effect on water, land or any habitats due to the use of it. Though some greenhouse gases are released while transporting fuel or extracting energy from uranium.

Have a great day. Keep asking questions!
