Below is the sequence of an mRNA molecule. Assuming there were no introns, 1. Write the corresponding DNA sequence below 2. How many amino acids long would the protein product of translation be for this mRNA? 3. How many tRNA molecules would be involved in making this protein? and Briefly describe the three things that occur before a mature messenger RNA is exported from the nucleus

00:01 Hello everyone for this question let us say that this is the mrna strand with us and we need to write the dna sequence okay so this is the mrna and for this the template strand will be c g t c g c g c c c c c g a t okay and the c c c c c c a t okay and the coding strand will be g c c c g c g c g c t t t t c t c t c c t c c c t c c c c c c c c c c c c c c c c c c c c c c c c g g g d d d t -c -t -t -a and a okay and now we need to tell that what amino acid will be coded here okay so let's suppose that this is the middle of the m -r -n -a so this g -c -a will code for ala and this g -c -g codes for ala -neen these are the synonymous coden.

01:22 The ugc codes for lysine, okay, and the uac codes for tyrosine, the ggu codes for glyc, okay, and the uacu codes for serene, and the uaa code for serene, and the uaa code, code, for stop codon so this here will be our polypeptide chain consisting of the six amino acids here okay and now we need to tell that how many trna molecules would be involved in making this protein so there will be one protein that will bring that will be charged with the amino acid alanine and the other other other trna will also be charged with the alenine with lysine tyrosine glycine and serine so there will be in all also so in total there will be 6 trn a that will be charged with the amino acids present here before the mrna is exported out of the nucleus into the cytoplasm it undergoes maturation process okay so the first process here is the capping okay so capping is done by the the enzyme guanile transferase which adds the gtp to the five prime end of the premature mrna and after that s.

03:16 Adenosyl, methionine, thyl transferase adds the methyl group at the seventh position of this gtp.

03:29 So this capping is known as 7thyl guano cinesdu.

03:42 That is joined via a 5 -5 -5 -prime triphosphate bridge and this is a co -transpe process and this is done at the 5 prime end of mrna...
