2- DNA replication, each strand of DNA serves as a _______ for a newly synthesized strand of DNA.
3- In gene expression, DNA is used as a template to make _______, which is then used as a template to make a polypeptide.
4- In the process of _______, DNA can be rearranged, which contributes to the genetic diversity of the species.

6- How can the central dogma help us understand the process by which DNA is turned into protein? What are the two steps involved in the process of gene expression?
7- Why are replication and recombination two important roles of DNA?

Answers

Answer 1

Answer:

1.hydrogen

2.template

3.mRNA

4.recombination

5.DNA and RNA are both made up of nucleotides. RNA is comprised of adenine, uracil, guanine, and cytosine. DNA is made up of adenine, thymine, guanine, and cytosine. DNA is a double-stranded chain of nucleotides comprised of base pairs that form a double helix. RNA is often a single-stranded chain of nucleotides.

6.The central dogma states that DNA contains the genetic code needed to make proteins—a process known as gene expression. Transcription and translation are the two steps involved in gene expression. In transcription, the DNA code is turned into RNA. In translation, the RNA sequence provides instructions to the cellular machinery to manufacture polypeptides, which become proteins.

7.Replication is the duplication of DNA, and it is important because, in cell division, each daughter cell must contain an exact copy of the original cell's DNA, since DNA contains the instructions required to make all of the cell's tissues. Recombination is the natural process for genetic sequences in a chromosome or between chromosomes to exchange genetic information. Recombination is important in nature because it produces genetic variations that may be preserved because of natural selection. Recombination also can be used in the laboratory to combine the genetic code of two different organisms.

Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? View Available Hint(s) Why do we classify lionfish populations near the eastern United States as an invasive species? What suggests that these new populations are not an expansion of the lionfish’s natural range? Lionfish are native to the tropical Pacific. There are no natural water routes of warm water between the Pacific and Atlantic oceans.

Answers

Answer:

Lionfish is introduced in this region.

Explanation:

The lionfish populations near the eastern United States is considered as an invasive species because this fish is not native species of this region and they were introduced into this region. Due to no predator available for this lionfish will make it invasive species that eliminated the local fish species and disturb the ecosystem. Lionfish are native to the tropical Pacific and there are no natural water routes of warm water between the Pacific and Atlantic oceans which helps this lionfish to reach eastern United States so we can say that it was introduced by humans.

How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?

Answers

Answer:

Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.

Explanation:

Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.

To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.

In some cases, people who test positive for genetic testing can receive
preventive treatments. For example, people who test positive for the breast
cancer genes BRCA1 and BRCA2 can have a preventive mastectomy (breast
removal surgery) before they develop the disease. In other cases, no preventive
treatments are available, but frequent monitoring can help detect a disease
earlier, when it's more easily treated.
What ethical or professional concerns does a health-care professional need to
address when he or she has a patient who wants to prematurely treat a genetic
disease? Do you think genetic testing should be part of normal preventive
healthcare? Why or why not?

Answers

Answer:

Discrimination occurs due to presence of "inferior" genes

Explanation:

Discrimination occurs due to presence of "inferior" genes is the ethical or professional concerns that the health-care professional need to  address when he or she has a patient who wants to prematurely treat a genetic  disease. Yes, I think that genetic testing should be a part of normal preventive healthcare because this genetic testing provides information about inheritable diseases. This testing can avoid future diseases by treating it before it causes severe damage to the body.

Answer:
this is an alternate answer that is simply paraphrased from the first answer (to prevent suspicion of cheating)
Explanation:

Discrimination arises owing to the presence of "inferior" genes, which is the ethical or professional dilemma that a health-care provider must face when he or she has a patient who wishes to treat a hereditary condition early. Yes, I agree that genetic testing ought to be a standard component of preventive healthcare because it informs us about inheritable disorders. By treating diseases before they seriously harm the body, this testing can prevent them in the future.

Climbing plants use other plants or rocks or man-made structures for support. Which of these is a climber? Why? a. Banana plant b. Sugarcane plant c. Grape plant d. Rice plant

Answers

Answer:

C.grape

Explanation:

The one that is a climbing plant is grapes. The correct option is C.

What is a climbing plant?

A vine is any plant with trailing or scandent stems, lianas, or runners. When used in wicker work, the term vine can also refer to the stems or runners themselves.

Creepers and climbers have thin, slender stems and cannot stand upright on their own.

Climbers, such as jasmine, grapevine, and money plant, require external support to grow vertically. Creepers, such as watermelon and pumpkin, grow horizontally on the ground.

A grapevine, also known as a grape, is a stem-tendril climber plant with cascading growth that grows in an upward direction.

Every year, new shoots emerge from this plant. It is grown to a height of 19 meters or more, depending on the pruning technique used.

Thus, the correct option is C.

Answers

Answer:

Due to absence of erosive agents.

Explanation:

The Maria have few craters compared to the surrounding areas because of no erosive agents such as winds and rain. The erosive agents only formed when there is atmosphere in the region. The atmosphere is responsible for the presence of winds and rainfall. If these erosive agents are present, there will be more craters as compared to the region where no erosive agents are present so that's why Maria have few craters in the region. as compared to the surrounding region.
