If you were to observe the process of translation in a cell, which molecule would NOT be there?

Question

a. mRNA
b. tRNA
c. DNA
d. amino acid

The concept of adaptive mutation suggest that

a. mutations in the genetic code are random in origin
b. mutations in the genetic code might be created in response to the environment
c. mutations weed out less desirable traits in a population
d. mutations force an organism to adapt to a new environment

A base substitution mutation would not change the number of nucleotides in the gene.
a. True
b. False
My microbiology students expose their bacterial cultures to short-wave ultraviolet light for 1, 2 and 3 minutes. The next class period they check to see if any cultures survive. Typically, any culture exposed for 2 minutes or more dies. How does ultraviolet light cause cell death?
a. spontaneous mutation b. adaptive mutation
c. induced mutation d. somatic mutation

Answer 1

1.For observation of translation there is no need of DNA directly in translation hence b is the answer.
2.Mutation is the key for evolution. And not the environment changes dna code but some mutation changes it. And the desirable one are to be survived. So b is our answer.
3. It's true subtitution doesn't alter the number of nucleotides.
4.It's the case of spontaneous mutation.

Answer 2

1. No DNA is involved in translation.

3. True (substitution means that a nitrogen base takes the place of the original nitrogen base -- no change in number)

Answer 3

DNA is not present in translations. This is when the RNA becomes a protein.

A base subsitution would not change the # of nucleotides.
