The molecule found on the 3' end of a DNA strand is a hydroxyl group (-OH) attached to the 3' carbon of the deoxyribose sugar. This hydroxyl group is crucial for DNA polymerization during replication, as it provides a site for the addition of nucleotides. In contrast, the 5' end of the DNA strand features a phosphate group attached to the 5' carbon of the sugar.

When DNA replicates what are the new DNA made of?
its made of DNA. Replication just doubles the DNA, just like when bacteria or humans replicate.. the new human is .. well made of human.... It is opposite and anti-parallel.... 5-AATGTC-3 Original strand 3-TTACAG-5 new strand Each new molecule will have 1 original strand, and 1 daughter/newly synthesized strand. DNA replication results in DNA DNA transcription results in a strand of RNA
Which strand would be the template for the leading strand?
The leading strand would utilize the 3' to 5' template DNA strand as a guide for continuous synthesis of complementary DNA in the 5' to 3' direction by DNA polymerase during DNA replication.
What is one strand of DNA that faces the opposite direction of the other strand called?
One strand of DNA that faces the opposite direction of the other strand is called the "antiparallel strand." In double-stranded DNA, one strand runs in the 5' to 3' direction, while the complementary strand runs in the 3' to 5' direction. This antiparallel arrangement is crucial for the processes of DNA replication and transcription.
How can you describe how DNA makes a copy of itself?
To reproduce a cell must copy and transmit its genetic information (DNA) to all of its progeny. Two strands of DNA are obtained from one, having produced tow daughter molecules which are identical to one another and to the parent molecule.
What is an enzyme that copies DNA to make a molecule of RNA is?
The enzyme that copies DNA to make a molecule of RNA is called RNA polymerase. During the process of transcription, RNA polymerase binds to the DNA template strand and synthesizes a complementary RNA strand by adding ribonucleotides in the 5' to 3' direction. This process ultimately results in the formation of messenger RNA (mRNA), which carries genetic information from DNA to the ribosome for protein synthesis.
What is located at the 3' end of DNA?
At the 3' end of DNA, there is a hydroxyl group attached to the third carbon of the sugar molecule in the DNA strand.
When one dna molecule replicated the result is two dna molecules what is true of the second dna molecule?
DNA actually has 3 forms. A-DNA, B-DNA, and Z-DNA. B-DNA is the kind you are most familiar with and present in most organisms. A-DNA can be found in dehydrated samples while Z-DNA is rare and mostly synthesized in the lab.
Why does a DNA strand grow only in the 5' to 3' direction?
A DNA strand grows only in the 5' to 3' direction because the enzyme that builds the new strand, called DNA polymerase, can only add new nucleotides to the 3' end of the existing strand. This is due to the structure of the nucleotides and the way they are connected in the DNA molecule.
How does DNA polymerase move along the DNA strand, from 3' to 5' direction, during replication?
DNA polymerase moves along the DNA strand in the 3' to 5' direction during replication by adding new nucleotides to the growing strand in a continuous manner. It reads the template strand in the 3' to 5' direction and synthesizes the new strand in the 5' to 3' direction. This process ensures accurate replication of the DNA molecule.
In what direction does a DNA molecule split during replication?
A DNA molecule splits in the 5' to 3' direction during replication. Each strand acts as a template for the synthesis of a new complementary strand.
Why does a new DNA strand elongate only in the 5' to 3' direction during DNA replication?
During DNA replication, a new DNA strand elongates only in the 5' to 3' direction because DNA polymerase can only add nucleotides to the 3' end of the growing strand. This is due to the structure of the DNA molecule and the way the nucleotides are arranged.
Why does a new DNA strand elongate only in the 5' to 3' direction during replication?
During DNA replication, a new DNA strand elongates only in the 5' to 3' direction because DNA polymerase can only add nucleotides to the 3' end of the growing strand. This is due to the structure of the DNA molecule and the way the nucleotides are arranged.
What does semi-conservative mean regard to DNA replication?
replicated DNA is made of one old strand and one new strand.
What is the term for the 3' to 5' strand of DNA?
The term for the 3' to 5' strand of DNA is the "antisense strand."
What are the differences between the 5' end and the 3' end of a DNA strand?
The 5' end of a DNA strand has a phosphate group attached to the 5th carbon of the sugar molecule, while the 3' end has a hydroxyl group attached to the 3rd carbon. This creates a directionality in the DNA molecule, with the 5' end being the starting point for DNA synthesis and the 3' end being the ending point.
DNA molecule antiparallel Why?
The DNA molecule is anti-parallel. This is because the two strands are the opposite of one another, such that if one strand has the base sequence ATC, the opposite strand would have the base sequence TAG.
What is the difference between the 3' and 5' end of DNA?
The 3' end of DNA refers to the end of the DNA strand where the sugar molecule has a free hydroxyl group attached to the 3' carbon of the sugar. The 5' end of DNA refers to the end of the DNA strand where the sugar molecule has a phosphate group attached to the 5' carbon of the sugar. This difference in chemical structure affects how DNA strands are oriented and synthesized during processes like DNA replication.
