Explain why the genetic code is called a triplet code

Biology
1 answer:
salantis [7]3 years ago
6 0
The genetic code is broken down into a series of codons on the mRNA. Each codon consists of 3 nucleotides which (normally) correspond to a single amino acid (e.g. AUG codes for methionine). I say normally because you can also have a codon indicate a stop codon (so no amino acid will be inserted and instead the polypeptide chain will terminate). This mRNA molecule with its list of codons will instruct a ribosome to synthesize a protein according to this code. 

This code is the set of rules - based on the triplet or codon. This triplet code is universal - all organisms use the same codons to specify the placement of each of the 20 amino acids in a protein.

Which characteristic do all protists have?
myrzilka [38]

Answer: They all survive in any environment.

Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.

I'll explain why the others aren't correct.

Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.

Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.

Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.

Let me know if you have any questions.

Mitosis is a process used for normal growth and development. Explain how and why a mutation in a BRCA gene may affect the cell c
Romashka [77]

Answer:

The BRCA gene is a tumor-suppressor gene found in the breast; to be more specific, it produces proteins that suppress cancerous activities/abnormal growth in the body. A mutation in a BRCA gene would allow these abnormal growth activities to go unchecked and thus increase the rate of mitosis. Cell cycle checkpoints would significantly be worse at their jobs of checking and correcting for errors during the cell cycle. Tumors would result as well, as cancerous growth continues, and the tumor can become metastatic.

In what stage of the cell cycle are the daughter cell produced
marshall27 [118]
The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same. You get the idea.
So it is the very last stage!
