Answer:
black is the dominant phenotype.
Explanation:
The black gene "overrides" the gene that codes for blue, thus making it dominant.
Explanation:
members of the same species battle each other to protect their young
In biopsychology, there is a system in the brain which is called the limbic system. The limbic system is responsible for one's memory, emotions and instincts -drives.
Many researchers suggest that the existence of emotions helped the animal kingdom to respond to sociality and survive better, emotion can also be translated into care and love. These traits also aid why infants, babies and other offsprings of animals are cared for which has a great influence on the survival of the species.
Amygdala, responsible for pain, aggression and grief which is anterior to the hippocampus factors why our memories have incorporated and is strengthened with emotions at that specific circumstance.
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.
