Question 25 (brainliest+20 points i could really use some ) using the codon wheel or chart shown above, determine the amino acid sequence encoded by the mrna strand below. mrna: gcu - aau - guc amino acid sequence: ? - ? - ? question 26 you must answer both parts of this question to earn full credit. a. use the codon wheel or chart above to determine the amino acids encoded by the following mrna sequences: uag, uga, and uaa. b. if a ribosome reads the mrna sequence uag, uga, or uaa during translation, what will happen?

Ans. 25.

Messenger RNA or mRNA has genetic information in the form of triplet codes, called as codons. These codons are made up of three nucleotide bases and each codon codes for a specific amino acid during protein synthesis.

According to codon chart, GCU codes for alanine (Ala), AAU codes for asparagine (Asn), and GUC codes for valine (Val). Thus, the amino acid sequence for the mRNA strand GCU - AAU - GUC is Ala-Asn-Val.

Ans. 26.

a). There are a total of sixty-four codons, made up of combinations of four nucleotide bases (4 X 4 X 4= 64). Out of sixty four codons, sixty one codons code for twenty amino acids that make proteins, while three codons (UAG, UGA, UAA) do not code for any amino acid and act as stop codons. Thus, no protein will be form with the mRNA strand UAG-UGA-UAA.

b). The UAG, UGA, and UAA are stop codons that act as signals to terminate the translation during protein synthesis. Thus, if a ribosome reads the mRNA sequence UAG, UGA, and UAA during translation, it will lead to termination of protein synthesis.

i think the answer is

mass

the answer is b)3/8x+1
