Answer:

a. preventing the cross-linkage of NAM subunits

Explanation:

The bacterial cell wall is made of peptidoglycan which is a polymer of alternating  N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) residues. The NAM residues  are crosslinked to impart additional strength to the cell wall.

Most of the antibiotics that target the cell wall synthesis in bacteria inhibit the enzyme of transpeptidation which in turn cross-links the NAM residues of the polysaccharide chains of the bacterial cell wall. Examples of these antibiotics include penicillins and cephalosporins.

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do
den301095 [7]

Answer:

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.

Hope this helps:)

Helga [31]
<span>The scientist who melted glass to simulate a microscope was Robert Hooke, in 1660. He was an English physicist, and he looked at insects and handheld objects. He named the cell for the cell of a monk, because to him it appeared to be a self-contained room.</span>

Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produ
Ivanshal [37]

Answer:

Explanation:

The double-stranded DNA molecule has the  potential to store genetic information in either strand, although in  most organisms <u>only one strand is used to encode any particular gene</u>.  

The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).

Thus, genetic  information is expressed by transcription of the non-coding (template) strand  of DNA, <u>which produces an mRNA molecule that has the same sequence  as the coding strand of DNA</u>. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.
