Answer:

DNA template strand 3' ________ 5'

DNA nontemplate strand 5' ________ 3'

Option B

Explanation:

DNA template strand is also the coding strand from which the mRNA is transcribed thus to transcribe an mRNA moving in the 5' to 3' direction, the template strand must run in the 3' to 5' direction while the non template which is the non coding strand and also is the same as the mRNA strand runs in the 5' to 3' direction.

The RNA polymerase moves and transcribes this mRNA in the 3' to 5' direction along the template strand.

Answer:

B) 3' - 5' direction along the template strand

Explanation:

Transcription is the first stage of gene expression or protein synthesis. It involves making a complementary strand of mRNA from a DNA template. The process of transcription is carried out by an enzyme called RNA polymerase. RNA polymerase initially binds to a specific region on the DNA called PROMOTER region. This triggers the initiation process.

The RNA polymerase then begins to read one strand of the DNA molecule called TEMPLATE strand. The template strand reads in the 3'-5' direction. The RNA polymerase, unwinding the double helix of the DNA as it progresses, reads the nucleotide bases on the template DNA strand and synthesizes complementary bases on the growing RNA molecule. The RNA transcript contains same information as the non-template DNA strand with the exception of Uracil base instead of Thymine. The RNA strand reads in the 5'-3' direction.

Hence, the RNA polymerase moves in the 3'-5' direction on the template strand during transcription.

How does atherosclerosis affect blood pressure?
mel-nik [20]

Answer:

Blood pressure is cardiac output versus resistance, especially in the capillaries.

Explanation:

suter [353]

Answer:

spatial

Explanation:

  • The pattern of organization is used by the writers to organize their ideas to effectively communicate the message.
  • The pattern of organization used can vary depending on the purpose of writing a statement.
  • The organizational pattern that is used in the sentence "The three parts of an insect's body are the head, the thorax, and the abdomen" is a spatial pattern.
  • Spatial organizational pattern organizes the information given in a sentence based on the physical relation of objects with each other. This pattern of organization is widely used by the writers to strike up an image of how the various parts are physically located.
  • Since in the given sentence the head, thorax, and abdomen are located one after the other in a cockroach's body, the pattern of organization used is spatial.

tangare [24]

Answer:

E) Elephants help other populations survive by repelling many large African predators

Explanation:

Elephants are large mammals. Elephants in Africa have a height of 4 meters and weigh up to 7 tons.

The role of elephants in the ecosystem is very important especially its impact both directly and indirectly on the environment. With a large size and height, other predatory animals such as lions, tigers, coyotes, hyenas do not want to get close to elephants. Elephants are animals that prefer to group. While still breastfeeding will be very protected by the mother for up to 3 years. Elephants have an average age of up to 70 years. Perhaps very few elephants have fallen prey to predators. Thus elephants are animals that indirectly protect other animals in Africa. Things like this also indirectly make grasslands become more fertile and other animal species also become more numerous.

So the most appropriate answer is E. E) Elephants help other populations survive by repelling many large African predators
