Answer:
A gene is a section of a chromosome that codes for trait.The specific combination of alleles an organism has is called its genotype which affects the organisms features.
Explanation:
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.
Mitosis should be the answer. if not that, then cell division. hope this helps :3
The best explanation that best predicts what happens to the trait over time is that the incidence of mid-digital hair will not change because it offers no selective advantage or disadvantage. A mutation is a sudden, spontaneous random change that occurs in the genetic make up of an organism. The presence or absence of mid-digital hair is controlled by a single gene with two alleles, and the allele H is dominant.
<span>Plants use carbon dioxide and sunlight to make their own food and grow the carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels most of the carbon quickly enters the atmosphere as carbon dioxide :) i love biology</span>
