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? 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 cytoplasn Previous

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
