How does the double-helical structure of dna explain how the molecules can be copied or replicated?.

Biology
1 answer:
Gemiola [76]2 years ago

Answer:

The DNA helicase comes and splits the hydrogen bonds that are holding them together which allows DNA primase and DNA Polymerase (3) to come and replicate the strands from 5' to 3'. Then both strands have half of the old and half of the new, and have a collected 2 double-helical structures, which means there is technically 1 copy.

Hope this helps!

You are a student doing summer healthcare work in a small village in Central America. You have been told that the local people h
Paladinen [302]

Answer:

Explanation:

In order to address iron deficiency in this village, locals will be encouraged to eat more of animal-based diet, especially beef, livers (from chicken, goat and cow), oysters, fish, chicken and turkey. This food sources contain high dietary heme iron which is is highly absorbed by the body.

Although plant sources also contain irons (in the form of non-heme iron) but these irons are not as absorbed by the body like the heme iron. However, the absorption rate of these non-heme irons can be increased by encouraging the locals to add fruits that contain vitamin-c (such as pineapple, orange, mango, grape, kiwi or strawberry) to there diet when they eat plant sources of non-heme irons like beans, spinach, nuts (cashew and almond), lentils and dried apricots .

I NEED HELP!!!<br><br> how can you survive a very cold winter
Rainbow [258]

Answer:

Prepare! Follow our winter survival kit checklist for tips on proper clothing, winter car kits, home supplies, and more.

Hypothermia and frostbite are the real dangers. Even in 50 F temperatures, you’re at risk of losing too much core and limb heat.

Protect your body heat. Protect it, trap it, and treat it like the precious resource it is.

Keep covered. Wind and exposure are the enemy. Exposed skin accelerates heat loss, especially through wind.

Dress in layers. The air trapped between each layer holds your body heat, like your own personal hot tub. Plus, layers give you better control over regulating body heat so you can avoid dangerous sweating.

Avoid sweating and stay dry. Besides moisture loss, sweating is bad because water on your skin makes you colder. That’s why we sweat to begin with — it’s the body’s air conditioning system.

Snow is an insulator. Don’t be afraid to use it for shelter.

Avoid eating snow. You lose a lot of core heat by melting snow inside your body. Melt it outside your body instead.

Alcohol does not warm you. Sorry, Russia!

Hydrate. Severe cold can be just as dangerous as severe heat. Stay hydrated.

Don’t travel unless you have to. Conserve energy. Stay where you’re most likely to be found. Especially if you’re in a nasty storm where navigation and shelter is difficult.

Answer:

A (bean)

Leguminous plants are plants that belong to the family FABACEAE and characterized by their possession of pods as fruits and ability to form nodules in their root for a symbiotic relationship to occur between nitrogen-fixing plants. An example of these leguminous plants that can be found in the option is BEAN.

Bean plant like all other legumious plants host certain bacteria called NITROGEN-FIXING bacteria in their roots in order to help them convert Nitrogen gas into usable compound forms. They, in turn produce carbohydrates for the bacteria. Leguminous plants store this nitrogenous compounds in their root nodules.
