Question

Replicate the following dna nucleotide sequence :

TACAAAAGTGTGTCTACACGCCACTGAGACATACGATTCCCAACT

Transcribe the template sequence ?

Translate the template sequence ?

Answer 1

Hi Kya,

Replicating the strand is fairly straight forward, Just match the template base with their complementary base. A pairs with T and C pairs with G. Using this we get:

TACAAAAGTGTGTCTACACGCCACTGAGACATACGATTCCCAACT

ATGTTTTCACACAGATGTGCGGTGACTCTGTATGCTAAGGGTTGA

To transcribe the the template we need to do the same thing but since we're making RNA, we replace T with U.

AUGUUUUCACACAGAUGUGCGGUGACUCUGUAUGCUAAGGGUUGA

Lastly, we need to decode or translate the mRNA to a protein. The easiest way to do this is to space the mRNA into codons of three bases. Reading from left to right (AUG is the universal start codon) we can make a protein using the codons.

AUG UUU UCA CAC AGA UGU GCG GUG ACU CUG UAU GCU AAG GGU UGA
