Why is the pairing of nitrogen bases key to understanding how DNA replication occurs?

Biology
1 answer:
Burka [1]3 years ago
7 0

The DNA replication occurs by preparing a new strand of DNA that is based on the template strand only. So understanding the nitrogen base pairing is very essential for understanding DNA replication.

<h3><u> Explanation:</u></h3>

DNA replication occurs prior to any type of cell division in all organisms. In case of humans, the DNA that is to be replicated needs to be de winded by means of decondensation of chromosomes into chromatin fibres and then to DNA fibres. Then there are enzymes like helicase and gyrase which helps in breaking the hydrogen bonds between two strands of DNA and to open it up for enzymes to get attached.

Then the enzyme DNA dependent DNA polymerase works on both the strands of DNA where it reads the mother DNA strand as a template and then brings deoxyribonucleotides complementary to the template strand and then polymerises it with the previous nucleotide to form a new DNA strand. Thus two DNA strands are produced which are again complementary to each other, leading to the production of a new daughter DNA. So, understanding the complementary base pairing is very essential to understand the DNA replication.

which statement best describes how the distance from a large river affects an areas climate in the summer
natulia [17]

Answer:

Regions near rivers experience winds from the water. This helps to regulate the temperature near large bodies of water by keeping the air warmer in the winter and cooler during the summer.

Explanation:

Water heats and cools more slowly than landmasses. Therefore, these regions will stay cooler in summer and warmer in winter, creating a more moderate climate with a narrower temperature range.

What kinds of advantages, in terms of evolutionary fitness, do cooperative behaviors provide among different species of non huma
Free_Kalibri [48]

Answer:

Throughout the overview segment elsewhere here, the benefits including its particular circumstance are listed.

Explanation:

  • Being willing to hunt with either a community relatively successfully, thereby increasing their likelihood of succeeding as well as physical inactivity.
  • Selective pressures such as illness as well as predators will assist to evolve altruism because grooming allows the person to have been groomed first, but also protects diseases from being transmitted through lack of hygiene.
  • Grooming encourages people to bond, which enables less friction and increases development by increasing security.

The atomic mass of an element is equal to the:
arlik [135]

The answer should be the third option "number of protons and neutrons." The atomic mass of a element is equal to the amount of protons, and neutrons added together in that element. So for example if we are trying to find the atomic mass of hydrogen you would add the total amount of protons and neutrons together to find it's mass although it doesn't equal the exact amount of it's mass but it's close.

Hope this helps.

Photosynthesis takes place in what cell organelle
Tems11 [23]

Answer:

chloroplasts

Explanation:

"<em>Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.</em>"
