I would say leaf cuz they also have different layers :)
Plz give brainiest if I am right
Good luck
Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.
Explanation:
DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.
<u>Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA.</u> In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).
In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.
A. they have a higher proportion of adenine–thymine than guanine–cytosine base pairs.
The option A represents the complete opposite of "high-gc gram-positive bacteria". High GC content means that this bacteria have more guanine ans more cytosine than the other base pairs- adenine–thymine. This means all the other options are correct.
When u need a question answered you click on the camera or you could even type it but I like the camera and u just take a picture of the problem and then u go to the most recent ones that have the correct question on it and scroll down and see the answers but for me I check if there are more than 2 answers of the same one before answering it.
Answer:
Ever since the existence of life of humans on Earth, the humans have been making progress to understand themselves and the mother nature.
In the start, the humans were hunter- gatherers. Hunter- gatherers can be described as humans which use wild life plants and animals for food. The humans used to live in jungles and eat the wild- life plants and animals. They used leaves from the trees to cover their bodies. Heat was produced by rubbing the rocks.
After this time, the humans learned the techniques of cultivating plants for food. They started cultivating crops and depend on them for living. During this time, humans learned the art of farming and agriculture. But they couldn't understand the effects of various pathogens infecting the crops and humans at that time.
After this time, humans learned the art of preserving foods in different forms like pickles etc. They also learned that certain types of plants could be used to treat wounds and other diseases.
With the passage of time, people learned to make and use machinery for making their tasks easier. The usage of machinery progressed rapidly and the industrial revolution began. People became more diverted to this sector rather than farming. They started to move towards the cities to find better jobs in industries.
Life after industrial revolution was much easier as humans had made a lot of equipments which aid them to have a better life style. Science has been developing since that time day by day.
