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

2133 how many amino acids are coded for mRNA strand of 6399 nucleotides.

Explanation:

mRNA is a product of transcription process in the nucleus of the cell.

mRNA is formed by using the template or coding strand of the gene sequence that is DNA.

The triplet codon on the mRNA transcript is read by anticodon of tRNA and suitable amino acid is brought for the process of translation. In this process primary protein structure is formed.

The triplet sequence coding for amino acid  can be checked from Genetic code table.

Thus total number of nucleotides in mRNA is 6399

to know the number of amino acids the total will be divided by 3 since 3 sequences code for 1 amino acid.

so,

2133 amino acids long primary protein will be formed.

Although there are non-coding regions in the mRNA as introns which are spiced off before translation, considering that given mRNA contains only exons.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

the correct answer is d
