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

Biology
1 answer:
sergey [27]3 years ago

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

Why are leaves green
gizmo_the_mogwai [7]
Leaves are green because of chlorophyll. Chlorophyll is a pigment found in the thylakoid membranes of the chloroplasts in the leaves.
Simply, plants are green because they have green chloroplasts (organelles that carry out photosynthesis).

Yes it is.

Carbon dioxide goes through plants, which they turn into oxygen. Humans and animals take in the oxygen and breathe out carbon dioxide. Then it repeats.

N 9 Viruses use the host's machinery to make copies of themselves. However, some human viruses require a type of replication tha
Amanda [17]

Answer:

<u>This is because  the Viron  has in its genome a specialized code  for synthesising any missed enzyme for replication that is lacking in the host cell.</u>

<u>An example is the replication of the human  DNA cells by the Immunodeficiency virus(HIV) </u>. Human  cells only have  enzymes for  copying  DNA templates, and   lacks the enzyme to convert the HIV  RNA genome  to human DNA.However these viruses have  in its genome; code for synthesising its own  RNA polymerase enzymes that copies  or transcribed  the   human DNA to HIV RNA.

 <u>This  ability of the viral cell  to code  for the host's enzyme  has a therapeutic effect</u>. Drugs can be targeted at the  viral polymerase enzymes to reduce the replication and therefore toxicity in the host cells.
