The mismatch of a DNA base pair during duplication can result in a mutation.True
False

Answers

Answer 1

Answer: The answer is true. Mutation is the result of the mismatch of a base pair during the duplication. Mutations are neither the results from errors during the replication of DNA or other types of damage to DNA. In simpler words, DNA errs to copy accurately.

Answer 2

Answer: The statemnt is true. Mismach is base pairs is one of the common types of mutations, that occur. This may be due to substitution caused by purine by purine, and pyrimidine by pyrimidine. The other type is transversion, in which, purne is replaced by pyrimidine, and pyrimidine by purine.

Which prevents the Lac genes in the DNA of E. coli from being expressed most of the time

Answers

The Lac repressor prevents the Lac genes in the DNA of E.coli from being expressed most of the time. The Lac repressor is actually a kind of DNA binding protein. It is a fact that in case there is an absence of lactose, the Lac repressor binds to the proteins. I hope that this answer comes to your help.

Answer:

The correct answer would be lac repressor.

Lac repressor refers to the DNA binding protein which inhibits or prevents the expression of genes in the DNA of Lac Operon.

The lac repressor protein is expressed by the Lac regulatory region.

It binds to the operator region of the operon and prevents the binding of RNA polymerase.

Find the sum of a 9-term geometric sequence when the first term is 4 and the last term is 1,024 and select the correct answer below.A.682
B.2044
C.2048
D.678

Answers

First, we need to solve for the common ratio from the data given by using the equation.

a(n) = a(1) r^(n-1)
1024 = 4 r^(9-1)
256 = r^8
r = 256^(1/8)
r = 2

Then, we can find the sum by the expression:

S(n) = a(1) ( 1 - r^n) / 1-r
S(9) = 4 (1 - 2^9) / 1-2
S(9) = 2044

Therefore, the correct answer from the choices listed above is option B.

Answer:
