If an mRNA strand is 6399 nucleotides long how many amino acids are coded for ( Numeric answer)
sergey [27]

Answer:

If an mRNA strand is 6399 nucleotides long, it will code for 2132 amino acids, as the last triplet is the terminating codon.

Explanation:

Codons are found in the RNA chain and are made up of nucleotides trios, whose specific sequence determines the genetic code.

There are 4 nitrogenous bases in RNA - Adenine, Guanine, Cytosine and Uracil - which when combined in trios give rise to 64 possible codon combinations that code for 20 amino acids, so an amino acid can be formed by more than one codon.

Determining how many amino acids are encoded according to the amount of nucleotides in the mRNA would be as easy as <u>dividing the number of nucleotids in the chain by 3</u>, but considering that the last codon is not taken into account, since it is the termination codon.

  • Amino acids = (amount of nitrogenous bases in mRNA / 3) - 1
  • Amino acids = (6399 / 3) - 1
  • Amino acids = 2133 - 1 = 2132

HELP ME, QUICKLY! Please and thank you. :)
LenKa [72]

The correct answer is The cell is prokaryotic because it does not have any membrane-bound organelles.

Explanation:

Prokaryotic cells are different from eukaryotic cells because prokaryotic cells do not have organelles surrounded by a membrane, while eukaryotic cells do. These organelles include a nucleus, ribosome, among others. On the opposite, the DNA material is located inside the cell forming an undefined structure and the cell is protected by the cell wall and the cell membrane. In this context, the cell of the image is prokaryotic because there are no defined organelles inside it.

Genrish500 [490]

Answer:

1) Consider what might have happened and modify the experimental method to retest the hypothesis differently.

2) Toss out any incorrect results that do not support the original hypothesis and repeat the experiment using the same methods.

3) Examine the procedural flaws that occurred during the experiment and summarize them in a conclusion statement.

4) Repeat the experiment, but this time adjust the new data to support the original hypothesis.

5) Toss out any incorrect results that do not support the original hypothesis and repeat the experiment using the same methods.
