<span>The toxin Bt (endotoxin CrylA (b)) Bacillus thuringiensis  that is a normal inhabitant of the soil, showed himself as a natural insecticide used by farmers engaged in organic farming. In contrast to the Bt-toxin produced by bacteria, genetic engineers included it pesticide in every cell of the seed, and therefore distributed throughout the adult plant, the products from which then are consumed by man. </span>That's why scientists are concerned that after the use of a BT toxin products people get antibiotic resistance and resistance to bt.

During translation, nucleotide base triplets (codons) in mRNA are read in sequence in the 5’ → 3’ direction along the mRNA. Amin
Paladinen [302]

Answer:

The question is incomplete, it lacks the mRNA sequence. The sequence is as follows:

5′−AUGGCAAGAAAA−3′

The answer is Met-Ala-Arg-Lys

Explanation:

Gene expression in living organisms involves the process of transcription and translation. Transcription is the synthesis of a complementary strand of mRNA from a DNA template while translation involves using the transcibed mRNA as a template to synthesize amino acid sequence (proteins).

In the RIBOSOME, where the synthesis of protein occurs, the mRNA nuceleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. The collection of all codons is the genetic code. Hence, for a specific mRNA sequence that reads 5′−AUGGCAAGAAAA−3′. The nucleotides will be read three at a time starting with AUG which is a codon that encodes METHIONINE.

Next, GCA is a codon that encodes ALANINE

Next, AGA is a codon that encodes ARGININE

Finally, AAA is a codon that encodes LYSINE.

Hence, the amino acid sequence using the above mRNA sequence, will read: Met-Ala-Arg-Lys

How does the structure of an amino acid replicate to its function in cellular processes? Use the role of amino acids in the stru
Alona [7]

A protein's shape directly affects how well it works. For instance, a protein works as a protective protein or a structural protein if its structure is fibrous, as is the case with proteins like collagen and keratin. The protein becomes denatured and ceases to serve its intended purpose if the structure of the amino acids is altered in any way.

<h3>What are amino acids?</h3>

Organic substances known as amino acids have both functional groups for amino and carboxylic acids. Alpha-amino acids, which make up proteins, are by far the most significant amino acids in nature, despite the fact that there are hundreds of other types. The genetic coding only contains 22 alpha amino acids. An organic compound is an amino acid. Carbon-hydrogen bonds are present in organic compounds. All amino acids share a similar fundamental structure. Each molecule has a core carbon atom that is joined to a hydrogen atom, a basic amino group, a carboxylic acid group, and an R-group, also known as a side-chain group.

Neuroglia do all of the following except:______. a. transmit electrical impulses. b. regulate interstitial fluid composition. c.
Ivenika [448]

Answer:

Option A, transmit electrical impulses

Explanation:

Neuroglia also known as glial cells which act as supporting cells for the nervous system and its functioning. These cells surrounds the neurons and produce insulation between them as they produce myelin sheath that coats the axon. There are six types of neuroglia cells and they all work to provide essential nutrients to the neuron cell and also maintain the homeostasis (under which it also regulate the interstitial fluid composition and repair tissue framework)

Hence option A is correct
