Use the double-stranded DNA molecule below to answer the following questions. The first pair of nucleotides (bolded) contains th
krok68 [10]

Answer:

The correct answer is 2. 5'-AUGUCAGGUACGCCACAU-3'

Explanation:

The template strand for transcription is 3'-TACAGTCCATGCGGTGTA-5 and RNA polymerase will add complementary mRNA sequence against this strand in the opposite direction i.e., 5' to 3' direction.

In RNA, A(adenine) makes complementary base pairing with U(uracil), not with T(thymine) and the rest of the base-pairing is same as in DNA. Therefore the correct mRNA produced from the transcription of this DNA molecule by the help of RNA polymerase is 5'-AUGUCAGGUACGCCACAU-3'.

Then this mRNA sequence will be used by ribosomes to synthesize proteins during the translation process.

Who is studying animals in the wild considered to be somewhat experimentally out of control
KIM [24]

Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.  

<u>Explanation:</u>

Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.

This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.  

Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.
