It not 1, but four components that make up the strand. These 4 nucleotides are guanine, cytosine, thymine, and adenine (G-C-T-A)

What does semi-conservative model mean?
Refers to semi-conservative replication of DNA. One strand of the old DNA is used as a template to replicate the other, new, strand of DNA. Thus you have four from two, but two of the four are old strands while the other two strands are new. Thus the name semi-conservative replication.
What must happen to a DNA molecule before RNA ploymerase can make RNA?
The double strand helix is opened by enzymes called helicase and this allow the RNA polymerase to copy the DNA strand. The double strand helix is opened by enzymes called helicase and this allow the RNA polymerase to copy the DNA strand.
Where is the process of making RNA from DNA Located in the cell?
Transcription (DNA -> RNA) happens in the nucleus where RNA polymerase makes single-stranded RNA from a template DNA strand.
What enzyme joins the nucleotides of a DNA strand together?
That depends on the process. During DNA replication, The nucleotides of the lagging strand (Okazaki fragments) are connected by DNA ligase. In transcription, the nucleotides of RNA are connected by RNA polymerase II.DNA Polymerse
Explain how DNA genes and chromosomes are related?
DNA is the molecule that genes are made of. Chromosomes are the (arbitrary) clumping that genes form in cells.
What makes up the sides of a DNA strand?
What makes up a DNA strand
Each DNA strand has a backbone that consists of alternating?
sugar and phosphate units/molecules.
Transcription makes a complementary strand of the DNA?
This Process Is Called DNA Transcription. *Apex*
The name of the five-carbon sugar that makes up a part of the backbone of molecules of DNA is what?
Deoxyribose.
What small DNA strand makes a copy of itself?
A virus is a small strand of DNA or RNA that copies itself.
At what part will DNA strand separate?
telomeres
Is DNA replication the same as DNA repair?
no replication makes a whole new strand of identical DNA while repair just replaces or cuts out mutations in the DNA strand
What sugar makes up the backbone for DNA?
deoxyiribose.
What are the two chemical groups that form the backbone of a DNA strand?
Deoxiribose and phosphate.
Which part of DNA is double helix?
The whole DNA strand is a double helix.
What is a part of DNA strand called?
Pyrimidines or Purines
What is the function of phosphate group in DNA nucleotides?
The phosphate in DNA bonds the 5 sugars together, and is also a backbone for the DNA strand :D
