Which of the following statements regarding restriction enzymes is NOT true?
Anni [7]

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.

How are mammalian cells similar and different from yeast? How can they be used to study cancer?
igomit [66]

Answer:

Hello, congratulations on your observation! Let me explain.

Yeasts are unicellular eukaryotic organisms. This implies that: they reproduce easily and quickly, they have all the characteristics of a eukaryotic model and their maintenance is really simple and economical (once their cultivation has been developed).

While it is true that they present differences with other eukaryotes, such as patterns of glycation and dependence and / or exclusivity of some substrates, but even if they are a cell model easy to use in the early stages of research, for example in cancer. It allows a first approach of the metabolic and cellular machineries that take place in our cells.  Later in the development of experiments, it may be necessary to use another study model, such as the mouse, rat or pig.

PLEASE HELP (i will mark brainliest)
Amiraneli [1.4K]

Answer: Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time. Renewable resources are resources that can be produced naturally and nonrenewable resources are resources that cannot be replaced. ... Things like fossil fuels, gas, oil and coal, we would use up those resources long before they could ever be replaced naturally.

Explanation: Yeah
