Question

section 6.2, continueddna replicationpractice 1the nucleotide sequences of \unzipped\ portions of dna are given below. in the blank, record the complementary nucleotide sequence.1 g c g a t a2 c t a c g a3 t t c a g g4 g g a t a tpractice 2answer the following questions about dna replication. darken the circle that corresponds to your answer choice.1. according to the central dogma of molecular biology, which of the following transfers of information is not possible?a from dna to dnab from dna to rnac from rna to proteind from protein to rna

Explanation:

Step1: Pair DNA nucleotides

In DNA, complementary base pairing rules are: G pairs with C, C pairs with G, A pairs with T, T pairs with A.

Step2: Solve for sequence 1

Original: G C G A T
Complementary: $\text{C G C T A}$

Step3: Solve for sequence 2

Original: C T A C G A
Complementary: $\text{G A T G C T}$

Step4: Solve for sequence 3

Original: T T C A G G
Complementary: $\text{A A G T C C}$

Step5: Solve for sequence 4

Original: G G A T A T
Complementary: $\text{C C T A T A}$

Step6: Answer multiple-choice question

Central dogma standard flow: DNA→RNA→Protein. Reverse flow (protein→RNA) is not possible.

Answer:

Practice 1:

1. $\text{C G C T A}$
2. $\text{G A T G C T}$
3. $\text{A A G T C C}$
4. $\text{C C T A T A}$

Practice 2:

1. D. from protein to RNA
