WHAT IF? DRAW IT The template strand of a geneincludes this sequence:3¿-TACTTGTCCGATATC-5¿. It is mutated to3¿-TACTTGTCCAATATC-5¿. For both wild-type and mutantsequences, draw the double-stranded DNA, the resultingmRNA, and the amino acid sequence each encodes. Whatis the effect of the mutation on the amino acid sequence?
Open reading frames...
correspond to introns, which are not read by the ribosome during translation
correspond to contiguous fragments of DNA sequence that do not contain a stop codon when read in a particular frame
correspond to contiguous fragments of DNA sequence that do not contain a stop codon when read in any of six frames
are often rich in acetylated histones which allow transcription
occur when fragments of DNA sequence are highly similar between two species
are recognized by ribosomes to initiate translation

Let's go over the key players in the process. MRNA. The mRNA is the code that is translated into a functional protein. It is created through transcription and a series of subsequent editing steps, which we have described in detail already. The mature mRNA comprises codons that will code for the production of a protein. lili 日arrow_forward

The genetic code is thought to have evolved to maximize genetic stability by minimizing the effect on protein function of most substitution muta- tions (single-base changes). We will use the six arginine codons to test this idea. Consider all of the substitutions that could affect all of the six arginine codons. (a) How many total mutations are possible? (b) How many of these mutations are "silent," in the sense that the mutant codon is changed to another Arg codon? (c) How many of these mutations are conservative, in the sense that an Arg codon is changed to a functionally similar Lys codon?arrow_forwardLearning Task 3: TRACE THE CODE dentify the amino acids coded for by the MRNA codon using the Genetic Code Table below.

The second letter of the MRNA on the second letter column (U) and the third letter on the right-side column (G). AUG codes for the amino acid methionine. To identify the amino acid.
