Which of the following accurately describes the process of translation? A. Each codon calls for a specific nucleotide.
B. Each tRNA molecule has a codon that matches an mRNA anticodon.
C. The process continues until a ribosome reaches AUG.
D. The process continues until a ribosome reaches UAA, UAG, or UGA.

Answers

Answer 1
Answer: The correct answer is C.
Translation is the second part of protein synthesis. In eukaryotic cells, this process takes place on the cell organelles called ribosomes that are located or found in the cell cytoplasm and in the endoplasmic reticulum.
Translation takes place in four stages namely activation, initiation, elongation and termination. Termination occurs when site A of the ribosome meets a stop codon which is either UAA, UAG or UGA. Since there is no tRNA that matches that codon, tRNA cannot connect to it. This stops the ribosome and the polypeptide breaks off the ribosome.

What are the strengths of the model the student created?

Answers

The strengths of the model the student created are it is clearly labeled and shows that oxygen and carbon dioxide is going in which direction.

What is a model?

A model is something that graphically describes any reaction or process. A model is made up of plastic or any solid material with colors. A model is a good way to show any process or work that has to be done at a big pace.

The model shows the movement of gas into and outside the body. The oxygenated blood transfer into the blood and the deoxygenated blood goes into the lungs.

Thus, the student's model has the advantage of being clearly labeled and showing which way oxygen and carbon dioxide are moving.

What make the phosphorus cycle different from carbon cycle

Answers

The phosphorous cycle differs from the carbon cycle in the way that it cannot be found in the gas form.Phosphorous is only found on land, in water and in sediment. 

Halophiles are a type of (1)_____ and are considered (2) _____lovers.1)eubacteria, archaea, or virus
2)virus, salt, or heat

Answers

Halophiles are atype of archaea and are considered salt lovers. Halophile organisms thrive in extreme environments thus they are also called extremophile organisms. They can be found in places with high salt content.

Halophiles are a type of archaea and Halophiles are considered salt lovers.

  1. Halophiles are a type of archaea.
  2. Halophiles are considered salt lovers.

Halophiles are microorganisms that thrive in environments with high concentrations of salt, such as salt flats, salt mines, and saline soils.

They have adapted to survive and even flourish in these extreme environments, which would be inhospitable to many other organisms. The term "halophile" is derived from the Greek word "halos," meaning salt, and "philia," meaning love or attraction.

These organisms are classified within the domain Archaea, a group of single-celled microorganisms that are distinct from both eubacteria and eukaryotes.

Fruit flies are eukaryotic organisms. Describe how the genetic material of a fruit fly is stored in its cells.

Answers

The genetic material of a fruit fly, like all eukaryotic organisms, is stored in the cell nucleus. Here's how it is organized:

1. **Nucleus:** The nucleus is a membrane-bound organelle within the cell where the genetic material is located. It is surrounded by a nuclear envelope, which consists of two membranes, and has pores that control the passage of molecules in and out.

2. **Chromosomes:** Inside the nucleus, the genetic material is organized into structures called chromosomes. In fruit flies (Drosophila melanogaster), they typically have four pairs of chromosomes, totaling eight chromosomes. These chromosomes contain the DNA molecules that carry the genes.

3. **DNA:** DNA (deoxyribonucleic acid) is the molecule that makes up the genetic material. It has a double-helix structure and consists of nucleotide units. Genes, which are specific sequences of DNA, encode the instructions for building and maintaining the organism.

4. **Histones:** DNA in the nucleus is wrapped around proteins called histones. This complex of DNA and histones is called chromatin. Histones help in packaging and organizing the long DNA strands within the limited space of the nucleus.

5. **Nucleolus:** Within the nucleus, there is a region called the nucleolus where ribosomal RNA (rRNA) is synthesized and ribosome assembly begins. Ribosomes are essential for protein synthesis.

6. **Mitochondria and Chloroplasts:** While most of the genetic material is in the nucleus, eukaryotic cells also have DNA in other organelles. Mitochondria (in animal cells) and chloroplasts (in plant cells) have their own small genomes, a remnant from their evolutionary origins as independent organisms.

In summary, the genetic material of a fruit fly is stored in the form of DNA, organized into chromosomes within the nucleus of its eukaryotic cells. This DNA contains the instructions for the fly's development, growth, and functioning.
