Describe the origin of each strand of the new double helices created after DNA

Biology

Alona [7]3 years ago

The process of DNA replication is a semi-conservative process; therefore each newly replicated helices contains one strand from the parent, and one daughter strand. 

Explanation; 
Replication of DNA is an important process especially during cell division, The two strands of DNA molecule have complementary base pairs and therefore, each of these strands contains the information needed to produce another strand. Each can be used as a pattern or template to produce a complementary strand. Finally each template and its new complement together form a new DNA helix, identical to the original. This is referred to as semi-conservative process because each new strand formed would have one strand from the original DNA molecule and a new complementary strand.

Zanzabum

Answer:

There are different types of reflexes, and some of them can be controlled voluntarily due to cortical processing.

Explanation:

Even if there is an initial myotactic reflex of moving away from the heat, the cortical processing that is subject to learning makes you not let go of the pan. It should be noted that there are different types of reflexes, and not all postural reactions are automatic. The cerebral cortex influences voluntary postural adjustment movements. Such control is mainly performed by the brain stem, where ocurrs the modulation of motor neurons and spinal cord interneurons through the lateral descending (fine movements) and medial (posture and balance) downward pathways.

What unifying theme brought the work of Mendel and Darwin together in the big picture of
fenix001 [56]

Answer:

A: Discovery of DNA as the genetic material

Explanation:

DNA is the genetic material and stretch of DNA that codes for a specific protein is called as gene. Discovery of DNA as genetic material provided the physical proof of Mendel's factors that were responsible for transmission of genetic traits in his experiment.

Discovery of DNA as genetic material also established that genetic variations among individuals of the species as described by Darwin are due to minor differences in their DNA molecules.

Hence, discovery of DNA as genetic material led to acceptance of both Mendel's law and Darwin's theory.

Hey there budd!

Your question is stated above: <span>Which option describes what the U.S. Green Building Council has created?

Based from my information, I know for a fact the the answer would NOT be option D. The government would not </span>to simplify the certification process for sustainable building and construction because they want (high) quality people working for them, not people who have low certificates to work for the government.

I (seriously) believe that the correct answer to this question would actually be the first option. (A) Government control over all engineering design materials. So, this would show you that the U.S. Green Building Council has created a government to watch over and control everything that is being designed.

I hope this helps you!
