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.
Part of the backbone in DNA that does not contain phosphorus?
The part of the DNA backbone that does not contain phosphorus is the deoxyribose sugar. It is the sugar molecule that forms the backbone of the DNA strand and is connected to the nitrogenous bases. The phosphate group is the component that connects the sugar molecules, forming the backbone of the DNA.
What type of sugar makes up the backbone of the DNA molecule?
The sugar found in the backbone of DNA is the deoxyribose.
What sugar molecules is involved in the structure of DNA?
Deoxyribose sugar molecules are involved in the structure of DNA. These sugar molecules are part of the backbone of the DNA double helix, linking with phosphate groups to form the sugar-phosphate backbone of the DNA strand.
What part of the shape backbone do the bases attach to?
The bases of DNA attach to the sugar component of the backbone, specifically to the 1' carbon of the deoxyribose sugar. The sugar is linked to phosphate groups, forming the backbone of the DNA strand, while the nitrogenous bases extend from the sugars, providing the genetic information.
The name of the five-carbon sugar that makes up a part of the backbone of molecules of DNA is what?
Deoxyribose.
Transcription makes a complementary strand of the DNA?
This Process Is Called DNA Transcription. *Apex*
What units make up The backbone of the DNA molecule?
The backbone of the DNA molecule is composed of alternating sugar (deoxyribose) and phosphate units. These sugar-phosphate units are connected by phosphodiester bonds to form the backbone of the DNA strand.
What make up the backbone of a polynucleotide strand?
The backbone of a polynucleotide strand is composed of alternating sugar (deoxyribose or ribose) and phosphate molecules. The sugar-phosphate backbone provides the structural support for the nucleotide bases, which extend from the backbone and form interactions with bases on the opposite strand in DNA or RNA molecules.
What small DNA strand makes a copy of itself?
A virus is a small strand of DNA or RNA that copies itself.
What constitutes the backbone of DNA?
The backbone of DNA is made up of sugar molecules and phosphate groups. These molecules form a repeating pattern along the length of the DNA strand, providing structural support and stability to the molecule. The nitrogenous bases are attached to this backbone, forming the genetic code of DNA.
What are the two chemical groups that form the backbone of a DNA strand?
The two chemical groups that form the backbone of a DNA strand are deoxyribose sugar and phosphate groups. These components link together to form a sugar-phosphate backbone, with nitrogenous bases attached to the deoxyribose sugar.
What part of the DNA ladder connects to phosphate?
In the DNA ladder structure, the phosphate groups connect to the deoxyribose sugar molecules, forming the backbone of the DNA strand. Each deoxyribose sugar is linked to a phosphate group, creating a repeating sugar-phosphate backbone that supports the nitrogenous bases. The nitrogenous bases, which include adenine, thymine, cytosine, and guanine, extend from the sugars and pair with complementary bases on the opposite strand.
