The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
So yeah xD

Answer:
Just letting you know that the meaning of a vestigial structure
Explanation:
It is a structure that has no purpose. For ex. a pig's back toe has no purpose it's just there. It doesn't function
9:3:3:1
Using white tall (RRBB)and black short (rrbb) as an instance
Then I have white tall:9
White short:3
Black tall:3
Black short: 1
So this shows the phenotypic expression of a heterozygous with a dominant and recessive growth
The four phenotype in this dihybrid in a Punnett square is stated above as 9:3:3:1
Thanks
The origin of life on Earth is a set of paradoxes. In order for life to have gotten started, there must have been a genetic molecule something like DNA or RNA capable of passing along blueprints for making proteins, the workhorse molecules of life. But modern cells can’t copy DNA and RNA without the help of proteins themselves. To make matters more vexing, none of these molecules can do their jobs without fatty lipids, which provide the membranes that cells need to hold their contents inside. And in yet another chicken-and-egg complication, protein based enzymes, encoded by genetic molecules, are needed to synthesize lipids.
