During DNA replication, the enzyme called _______ unwinds the DNA do

Medgie is creating his science fair project on DNA replication. His final display board shows the following. Human DNA Replication Steps Step 1 DNA unwinds in the nucleus Step 2 Complementary base pairs are deleted Step 3 DNA rewinds back together Step 4 The newly made DNA helix is placed in a cell formed in Mitosis According to Medgie's project, which of the following identifies and explains which of the steps is incorrect? O Step 4 is incorrect because not all human cells require DNA. O Step 3 is incorrect because the DNA remains unwound to be transcribed into RNA. Step 2 is incorrect because the complementary base pairs are used as a template, not deleted. Step 1 is incorrect because DNA doesn't unwind in the nucleus, instead it unwinds in the cytoplasm Previous

Can you help find the best answer for this question about DNA

During DNA replication, the helicase enzyme binds to DNA and Select one: a. prevents the DNA strands from rewinding back into the helical shape b. cuts the double stranded DNA into single strands c. provides the starting point where new nucleotides can be added d. adds new nucleotides to the template strand

True or false: The synthesis of a new strand of DNA is initiated using a DNA primer?

Shown below is a DNA coding strand. A base (*G*) mutates to Adenine (A). What will be the resulting amino acid sequence as a result of the mutation? What type of mutation occured? Hint: Determine the template, then first determine the amino acid sequence before the mutation, and then determine the amino acid sequence after the mutation. Show how you got your answer. 5' T-A-C-T-T-C-C-A-*G*-C-C-G-C-T-C 3'

In DNA replication, what is meant when we say it is “semi-conservative”?    a. One new DNA molecule contains the parent strands and the other DNA molecule contains only new strands b. Both new DNA strands contain a parent strand and a template strand c. The new DNA molecules are exactly like the original strand d. Some of the genes are replicated, some aren’t
