What are the reasons for ultra-thin and transparent nature of epidermal cells?​
Basile [38]

Answer:

Epidermal cells secrete the waxy hydrophobic substance cutin that polymerizes on the surface, forming a barrier to water evaporation. Epidermal cells are transparent because their plastids remain small and undifferentiated; hence light readily penetrates through to the photosynthetic tissues beneath the epidermis.

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.

kirill115 [55]
<span>These are organelles.
An organelle is the part of a cell that has a specific purpose in a cell. The structure of the cell is made up of many different organelles.  The chloroplast consists of chlorophyll and the cell wall. The chloroplast helps with photosynthesis. Animal cells do not contain chlorophyll as they do not need photosynthesis to generate energy.  A plant is unable to turn the sun's rays into a food source without photosynthesis.
