Based on the DNA strand below, and assuming the promoter for this gene is located to the le\, which protein sequence below does
Art [367]
<h2>Protein sequence</h2>

Explanation:

  • The given sequence is of coding strand(5'-3' direction)

5’-ATGTTGAAAATGCCGTAGAGGC-3’  

  • Protein is made up of mRNA and mRNA has the same sequence as coding strand(only T is replaced by U) so the sequence of mRNA will be:

5’-AUGUUGAAAAUGCCGUAGAGGC-3’

According to the genetic code,3 bases code for one nucleotide and further nucleotide codes for amino acid,amino acids forms the base for protein

  • AUG codes for Methionine(Met)
  • UUG codes for Leucine(Leu)
  • AAA codes for Lysine(Lys)
  • AUG codes for Methionine(Met)
  • CCG codes for Proline(Pro)
  • UAG codes for stop codon(Stop)

Once the stop codon comes protein synthesis will be stopped,so the final protein sequence will be:

Met-Leu-Lys-Met-Pro-Stop

California condors, large, predatory birds that were previously on the edge of extinction, have benefited from a program that ra
Nikolay [14]

Answer:

To create policies to <em>control or forbid</em> the use of DDT

To create educational programs for the people.

Explanation:

As the individual can not be controlled once it is released, the actions to take abut this problem must be focused on other perspectives. Two main actions would be usefull to improve the condors´ situation:

One of them is to create policies to control or forbid the use of DDT, to reduce contamination in different food and water sources. There are too many animals that get contaminated for feeding on vegetables or other animals grown on perturbed soil, and for drinking polluted water. When these animals die, condor feeds on them and also dies. It is important to avoid using these products that affect the whole biodiversity, including human beings.

The other action is to educate people. It is very important to create educational programs that are accessible to everybody and by which it is possible to teach people about the condors´ biology, feeding behavior, and reproductive rate, among others. People should know that these animals are not dangerous, that they only feed on dead animals, and that their reproduction rate is very low. If people do not have any knowledge about this species and its situation, they will not be able to protect it.

Systematists have used a wide variety of traits to reconstruct the phylogenies of particular groups of organisms. Which one of t
NemiM [27]

Answer:

All of the above traits combined

Explanation:

Phylogeny is an evolutionary history of development of a certain species or taxonomic group.

The purpose of phylogenies is to represent evolutionary relationships among a group of organisms.

During the reconstruction of phylogenies. Systematists often use a variety of traits in order to produce a good estimate of a phylogeny.

The use of molecular traits, gross morphological traits, behavioral and biochemical traits  combined can give a good estimate of a phylogeny.
