What else can I help you with?
What must happen before meiosis can begin?
DNA replicates and forms tetrad—APEX.
What must happen before a cell divides?
Before a cell can dividess, it makes a copy of its DNA (deoxyribonucleic acid).
What process is the first step in making a protein from DNA instructions?
The first step in creating a protein is transcription - the copying of the code from DNA to mRNA. (The section of DNA must unwind before this can happen).
What must happen to the DNA before transcription can take place?
Before transcription can take place, the DNA in the cell nucleus must be unwound and separated into two strands by enzymes. This process exposes the genetic information that will be transcribed into mRNA.
What must happen before meiosis begins?
A duplication of the chromosomes is what must happen before meiosis can begin.
What k must happen before meiosis can begin?
A duplication of the chromosomes is what must happen before meiosis can begin.
What must happen to a DNA molcule before RNA polymerase can make RNA?
Before RNA polymerase can make RNA, the DNA molecule must be unwound and the double helix separated to expose the sequence of nucleotides that will be used to transcribe the RNA. This process is facilitated by proteins that help open the DNA molecule for transcription.
What must happen to a DNA molecule before RNA polymerase can make RNA?
The DNA molecule must first unwind and separate into two strands. This process is called transcription, during which RNA polymerase can then read and transcribe one of the DNA strands to synthesize RNA.
Cells must copy their DNA before they do what?
Cells must copy their DNA before they undergo cell division. This ensures that each daughter cell receives a complete set of genetic information.
What must happen to DNA strands before transcription can begin?
The DNA strands must separate or unwind to expose the specific gene that is going to be transcribed. This process is facilitated by enzymes that help unzip the double-stranded DNA. Once the DNA is unwound, RNA polymerase can then bind to the DNA and initiate transcription.
What must happen to DNA before it can replicated?
Before DNA can be replicated, it must undergo a process called unwinding, where the double helix structure is separated into two single strands. This unwinding is facilitated by enzymes such as helicase. Additionally, the strands must be stabilized to prevent them from re-annealing or forming secondary structures, allowing DNA polymerase to synthesize new complementary strands based on the original template strands.
What must energy be turned into before it can be used?
