Correct answer: Glycogen
Glycogen is a form of polysaccharide of glucose molecule which serve as energy storage unit in the humans. The excess glucose in the body is stored in the form of glycogen in the muscles and the liver.
The muscles can store upto 500 gram of glycogen and liver can store 100 gram of glucose. Therefore, any carbohydrate which is consumed beyond this limit are converted to and stored as fat.
Glycogen that are stored in muscle are broken down into glucose while the liver cell glycogen are broken down into glucose as a circulating energy source to be used by the body.
Answer:
The environment is affected by the biotic and abiotic factors such as temperature, pressure, humidity and organisms like human activity. Some factors that affect environment are the following : a) Greenhouse Effect - Green house gases like C O2, trap the heat from the sun that increase the temperature of the earth.
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.
