What is an advantage of using transgenic bacteria to produce human proteins?

Answers

Answer 1

Answer: Transgenic bacteria produce human proteins in a greater amount.

Bacteria are simple organisms with fast reproduction. The bacterial population can double its size every 20 minutes. So, they are very suitable for growing in the culture and for genetic modifications. Nowadays, it is easy to modify bacterial genome to produce desired proteins, such as insulin, human growth hormone, etc. Thanks to its quick reproduction, desired proteins are produced in greater amount for a short period of time.

The isotope of an atom containing 31 protons and 39 neutrons suddenly has two neutrons added to it. What isotope is created?

Answers

The answer is gallium-72. The isotope of an atom containing 31 protons and 39 neutrons suddenly has 2 neutrons added to it. So, it has 31 protons and 41 neutrons (39 + 2 = 41). The mass number of an element is the sum of the number of its protons and neutrons: 31 + 41 = 72. The atomic number of an element is the number of its protons. This isotope has 31 protons and its atomic mass is 31. According to the Periodic table, gallium has atomic mass of 31. Thus the isotope is gallium-72.

Microbial cells are grouped into two major groups based on the separation of their genetic material from the cytoplasm. Which are these two groups?

Answers

Answer:

Eukaryotic microbes and prokaryotic microbes

Explanation:

Some microbes such as bacteria do not have a membrane-bound nucleus. So, their genetic material lies in the cytoplasm itself. These microbes are called prokaryotic microbes. All the bacterial species are prokaryotes. Example: E. coli.

On the other hand, some microbes have a well define nucleus to house their genetic material. These microbes are called eukaryotic microbes. Fungi and protists are the eukaryotic microbes. Example: plasmodium and slime mold.

What effect has breast cancer research had on society? People who have gene mutations have more treatment options. People now face an increased risk of breast cancer. The complete history of breast cancer is now known. Breast cancer research has no impact outside of a lab.

Answers

Answer;

People who have gene mutations have more treatment options.

Explanation;

-Breast cancer is a complex disease with no simple solution, which is why researchers are tackling it from every angle. Researchers around the world are working to find better ways to prevent, detect, and treat breast cancer, and to improve the quality of life of patients and survivors.

-Some of the active areas of research include; Breast cancer causes, causes and treatment of metastatic breast cancer, reducing breast cancer risk, and breast cancer treatment among others.

Why is DNA replication describe as semiconservative

Answers

Semiconservative DNA replication is a mechanism of DNA replication which results in two copies of DNA, each consisting of one parental DNA strand and one newly synthesized. Each strand of DNA helix serves as a template for new strands. The new strand remains associated with template strand.
Oppositely, in conservative DNA replication, each strand of DNA helix serves as a template for new strands, but new strands separate from template strands and associate into new DNA, so one DNA copy has both original strands, and another one has both new strands.

Why are women often carriers of X-linked traits but rarely affected by them?

Answers

Women have two x chromosomes, compared to men who have one x and one y chromosome. Because of the two x chromosomes, one of them can override the other. In men they only have one x and one y, they don't have the extra x chromosome to override the allele.

Women have two X chromosomes.Recessive alleles on one X chromosome are often masked by dominant alleles on the other chromosome.Women will not be affected unless they receive two recessive alleles.
