QUESTION 1 The genetic code is said to be ordered. What does that mean? A. There is an order to the codon sequence, if you change the order of the three O B. Codons that encode for similar chemical properties are usually different by one ° C nucleotides, it is a different codon. nucleotide ·More than one codon can code for the same amino acid s D. One codon can encode for more than one amino acid. QUESTION 2 We say that the genetic code is nearly universal, we mean that choose the best answer) 0 A. All organisms use nucleotides as the genetic code. O B. In almost all organisms, the same codon encodes for the same amino acid. ° C. Although there are some exceptions, in almost all organisms, the start codon and the stop codons are the same. OD. B and C

Explanation / Answer

Question 1 ) Answer is B

Question 2) Answer is D( B and C)

All most all organisms same codon codes for same aminoacids

mitochondria, chloroplast, and protist that with the codon UAA, and UAG, instead of functioning as stop codons, the code for Glutamine.

Question 3) Answer is C

three main stages involve in transcription

Initiation elongation and termination

Question 4) Answer is D

In prokaryotes, the promoter consists of two short sequences at -10 and -35 positions upstream from the transcription start site.
