Option 4 is the answer.
The genetic code is based on three -nucleotide codons that are read in a sequential and non-overlapping manner.
The genetic code is based on a -nucleotide codons that are read in a b and...
Is the following statement TRUE? "If the genetic code consisted of 2-nucleotide codons (instead of 3), it would only be able to code for 8 different amino acids."
1) The universal genetic code is used to translate aminoacids from a. codons in the DNA b. codons in the mRNA c. codons in tRNA d. codons in rRNA 2) In RNA, introns are: a. nucleotide sections that do not code for proteins and are not removed before translation b. nucleotide sections that code for proteins and must be removed before transcription c. nucleotide sections that do not code for proteins and must be removed before translation d. nucleotide sections...
Because the genetic code is nonoverlapping, a missense mutation (from a single nucleotide change) results in the alteration of ______________, and the resulting protein has ______________. a) only one codon / at least three amino acid changes b) three codons / a single amino acid change c) only one codon / a single amino acid change d) three codons / three amino acid changes
Assume you found life in Mars. If the Martian genetic code used the
nucleotide "A" as a spacer, and then the nucleotides T, C and G in
triplers, how many different codons would be available?
a) 3 b) 4 c) 8 d) 9 e) 12 f) 20 g) 27 h) 30 i) 64
would be purine rich (AG rich) d) Actually, it would be pyrimidine rich (TC rich) __17. Rosalind Franklin received the Nobel Prize for: a generating X-ray crystallographic...
Question: the genetic code _____?
a) consist of 64, 3-base codons
b) consist of 4, 1-base codons
c) consist of 16, 2-base codons
d) consist of 2 STOP codons
Question 13 The genetic code consists of 64, 3-base codons consists of 4, 1-base codons consists of 16. 2-base codons consists of 2 STOP codons
The genetic code is read in groups of three (3) nucleotides called codons. Some mutations are silent because they have no effect on the phenotype. How is that possible? Since there was a mutation in one of the codons, that gene will not be expressed. o It is not possible, mutations are always expressed and always have an effect The mutation changed the codon but the new codon codes for the same amino acid The ribosome knows there was a...
Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...
How many of the 64 possible triplets in the genetic code are stop codons? A. 1 B. 3 C. 5 D. 7 E. 61
Chapter 15: 1. What is the significance of the fact that many synonymous codons differ in the third nucleotide position? 2. Define the following terms as they apply to the genetic code: a. Reading frame b. Overlapping code C. Nonoverlapping code d. Initiation codon e. Termination codon f. Sense codon 8. Nonsense codon h. Universal code i. Nonuniversal code 3. What role do the initiation factors play in protein synthesis? 4. Compare and contrast the process of protein synthesis in...
Question 36 The genetic code is a listing that gives the relationship between? O codons and amino acids O codons and anticodons codons and genes anticodons and genes Question 37 A human cell normally contains how many chromosomes?
