Suppose a plant breeder wants to isolate mutants in tomatoes that are defective in DNA repair. However, this breeder does not ha
Nana76 [90]

The provided question has marked options incorrectely the correct order as follows:

A) Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.

B) Measure the amount of post-translational processing that occurs in the putative DNA repair mutant plants.

C) Measure the somatic mutation rates for the putative DNA repair mutant plants.

D) Expose the putative DNA repair mutant plants to a deaminating agent and select those that have a decreased mutation rate.

E) Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Answer:

The correct answer is: A), C) and E)

Explanation:

The breeder wants to isolate the mutants in tomatoes that are defective in DNA repair, to identify such plants breeder should follow these methods as they will allow best to identifying the defective tomatoes-

Measure the somatic mutation rates for the putative DNA repair mutant plants.

Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.  This will allow the breeder to see and analyze the ability of DNA repair in tomatoes

What is the approximate percentage of guanine in the DNA genome of E. coli?
Nadya [2.5K]

Answer:

25%

Explanation:

<em>The approximate proportion of G + C content in the genome of E. coli has been reported to be 50%. According to Chargaff's rule, the amount of guanine in any DNA must be approximately equal to the amount of cytosine. </em>Hence,

if G + C = 50 and G = C,

then

G = C = 25

Therefore, the approximate percentage of guanine in the genome of <em>E. coli </em>would be 25.

You have a strand of DNA with the nucleotide sequence AGATCGATT. The complementary strand will have which of the following seque
enot [183]

Answer:

The answer is B

Explanation:

with complementary strands A goes with T

and G goes with C

   so         AGA TCG ATT

becomes TCT AGC TAA

you can see how you swap A's with T's and C's with G's. and vice versa.
