Answer:
MARS
Explanation:
Mars represents the 4th planet of the solar system, being next to the earth. It is comprised of a hard and solid surface and the average surface temperature of Mars is extremely cold, which is roughly about -60°C. The atmosphere of Mars is very thin, which is dominantly comprised of CO₂ gas (almost 95%), along with some molecular Nitrogen (3%) as well as there is the presence of Argon (2%). In addition to this, it is also composed of dust clouds within its atmosphere. There is the absence of a magnetic field in Mars, due to which the solar wind highly affects the atmosphere of Mars.
Answer:
The correct option is option A
Explanation:
Restriction enzymes are endocleases that cleave DNA fragment (<u>of usually four, five or six nucleotide long</u>) at <u>specific sites to produce blunt or sticky ends</u>. They <u>recognize palindromic sequences of host DNA when cleaving the specific sites</u>. The sequences below (on complementary strands) give an example of a palindromic sequences.
5'-CCC║GGG-3'
3'-GGG║CCC-5'
As can be seen above, when read from 5' to 3', the two sequences are the same despite being on opposing strands. And when cut between the guanine (G) and cytosine (C) (as shown above), it produces a blunt end. But when cut as shown below produces a sticky end.
5'- G║AATTC -3'
3'- CTTAA║G -5'
The explanation above shows options C and D are right while option A is wrong (hence the correct option).
Also, bacteria prevent their own DNA from been digested by restriction enzymes by adding methyl group to their restriction sites <u>which prevents restriction enzymes from recognizing restriction sites of their DNA;</u> this generally makes bacterial DNA to be highly methylated. This explanation makes option B right also.
