How does the eukaryotic initiation complex locate the true start codon?

Biology
1 answer:
aliina [53]3 years ago
4 0

Answer:

The initiation complex moves the small ribosomal subunit through the 5 UTR, scanning for the start AUG.

Explanation:

Eukaryotic translation is the process by which mRNA is translated into proteins in eukaryotes. It has three stages: initiation, elongation and termination.

Eukaryotic initiation complex is formed in initiation stage. It forms when the small ribosomal sub unit (40s) along with some eukaryotic initiation factors (eIF1, eIF3 etc.) recruits the initiator tRNA. The initiator tRNA has anticodon CAU which corresponds to first codon AUG on mRNA and carries methionine amino acid.

The whole initiation complex binds to the 5' end of mRNA. It begins to scan it from 5' UTR (untranslated region) to 3' end until the start codon is encountered. Once it is encountered, translation process finally begins with the first amino acid being methionine.

FromTheMoon [43]

Answer:

Number of chromosomes

Explanation:

Meiosis is a specialized type of cell division in which the gametes are produced.

A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.

Therefore, meiosis changes the number of chromosomes.

According to the excerpt above from a health journal, what decision can an athlete make regarding his diet?
shepuryov [24]

The correct answer is A. His diet should include foods such as eggs, nuts, and fish.

Explanation:

The excerpt from the journal explains the importance of protein intake for athletes as this contributes to many body functions such as "enzyme production" or "growth and repair of tissues". In this context, athletes will need to have an appropriate protein intake, which is essential to growth muscles or repair them if there is a lesion. Moreover, this can be obtained through the intake of foods such as eggs, nuts, fish, grains, among others. In this context, the best decision is expressed in option A.

Give an example of exploitative and interference modes of competition for interspecific and intraspecific competition. Explain a
kherson [118]

Answer:

Separating the effect of resource use from that of interference is not easy. A good example of exploitative competition is.

For example, large aphids (insects) defend feeding sites on cottonwood leaves by kicking and shoving smaller aphids from better sites. In contrast, during exploitative competition, organisms interact indirectly by consuming scarce resources.
