Given the template strand DNA sequence 5'-TCA AAA TGG ATT CAT-3', what is the corresponding mRNA sequence (written 5'-3')?
Sergeu [11.5K]

Answer:

The correct answer is C) AUG AAU CCA UUU UGA.

Explanation:

First important thing to notice is that RNA doesn't have Thymine, all thymines are changed for Uracils. Then, the correspondency is thymine-Adenine, Guanine-Cytosine (and viceversa) Adenine-Uracil. Lastly, the transcription process happens from 3' to 5', so the question asks for the final result to be read to the opposite direction. Therefore, the correct answer is C.

What is a possible consequence of increased ocean temperatures due to global warming? Mark all that apply.
dsp73

Answer:

Coral reef bleaching

Explanation:

<em>The correct answer would be coral bleaching.</em>

Coral bleaching is generally define as the change in color that results from the expulsion of green symbiotic algae from the tissues of the coral.

The expulsion of symbiotic algae from the tissue of coral is usually caused by a change in stressor factors of ocean water such as light, temperature, nutrient.

<u>When the temperature of ocean water increases as a result of global warming, the vibrant color of corals may be lost because the change in stress condition usually leads to the degradation of the algal pigments or outright expulsion of the symbiotic algae from the tissue of the corals. When this happens, it leaves the coral tissues completely white and they are said to have been bleached.</u>

Dna plays a major role in heredity, composing the genes that are passed down from parent to offspring. It also plays a major rol
Eduardwww [97]

DNA plays a major role in heredity, composing the genes that are passed down from parent to offspring. It also plays a major role in the everyday workings of your cells. It does this by creating molecules, such as enzymes, that regulate cell functions. These enzymes belong to a larger class of molecules known as Proteins.

  • DNA is important in terms of heredity. It packs in all the genetic information and passes it on to the next generation. The basis for this lies in the fact that DNA makes genes and genes make chromosomes. Humans have 23 pairs of chromosomes – a total of 46 chromosomes.
  • Information that is stored in DNA molecules is used to manufacture proteins through the process of transcription and translation.
  • During transcription, DNA molecules are used to generate mRNA (messenger RNA), which then undergoes translation in the cytoplasm to generate proteins. These proteins include enzymes that control or regulate and catalyze different biological reactions in the body.
  • Additionally, one of the characteristic of protein is being protein in nature which means like proteins they are produced through translation in the ribosomes.

Why are a plants stomata generally open during the day and closed at night brainly?
bagirrra123 [75]
To keep in the stored enzymes so it can keep synthesizing at night, even when there is no sunlight. -- Stomata serve two main functions - they allow carbon dioxide to reach the cells in the leaf where the majority of photosynthesis takes place and they allow water to be transpired out off the leaf. During the day, stomata are generally open to allow photosynthesis to take place as quickly as possible. At night, when the lack of light means photosynthesis can't take place, many plants close their stomata to reduce water loss. There is one group of mainly desert plants, known as CAM plants, that keep their stomata closed during the day when water loss would be greatest, and open them at night, using a biochemical method to effectively store carbon dioxide in the leaf overnight.
