What else can I help you with?
During DNA replications a complementary strand of DNA is made for each original DNA strand thus if a portion of the original strand is CCTAGCT then the new strand will be?
GGATCGA. Each base in the original DNA strand pairs with its complementary base (A with T and C with G) in the new strand during DNA replication.
Semiconservative replication involes a template what is the template?
The template for semiconservative replication is the original DNA strand that serves as a guide for creating a new complementary strand. During DNA replication, each original parental strand acts as a template for the synthesis of a new daughter strand.
Is Each strand in the double helix is identical to the opposite strand?
Each strand in the double helix is complementary rather than identical to the opposite strand. The bases in one strand pair up with specific bases in the opposite strand according to the base pairing rule (A with T and C with G). This complementary base pairing allows each strand to serve as a template for the synthesis of a new strand during DNA replication.
Can DNA be described as conservation?
DNA replication is semi-conservative. This means that each new DNA molecule has one original strand of DNA and one new strand of DNA.
What does semi-conservative men in regard to DNA replication?
It means when the DNA is unzipped into two strands each strand serves as a template for the synthesis of another new strand. So, when the strands come back together in the double helix one strand is an old strand and one is a new strand with you now have double the DNA you started with; four strands in all.
What is the process in which the DNA double helix unfold and each strand serves as a template for the synthesis of a new strand?
The process is called DNA replication. It begins with the unwinding of the DNA double helix by an enzyme called helicase. Each separated strand then serves as a template for the synthesis of a new complementary strand by DNA polymerase.
At the end of replication each new DNA molecule is composed of?
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
How DNA replicates?
DNA first unwinds by the polymerase into two strands, then polymerases run over the two strands, replace a new strand on each old strand, forming two new DNA with one new strand and one original strand in each. (The polymerase is the enzyme)
What happens after replication?
each new DNA double helix consists of one old strand and one new strand
During DNA replications a complementary strand of DNA is made for each original DNA strand thus if a portion of the original strand is CCTAGCT then the new strand will be?
GGATCGA. Each base in the original DNA strand pairs with its complementary base (A with T and C with G) in the new strand during DNA replication.
IMPORTANT After DNA replication does half of the old strand leave with half of the new strand?
The process of DNA replication is described as being semi-conservative. The complementary DNA strands are pulled apart, new matching nucleotides are connected to each separate strand, and the result is two new strands that each contain exactly one-half of the original DNA strand.
When one DNA molecule is copied to make two DNA molecules the new DNA contains what percent of the parent DNA?
DNA replicates semiconservatively. This means 50% of the parent DNA is retained in each new molecule/double helix. DNA unzips and allows 2 new sugar-phosphate backbones to be inserted, each 'reading' off one of the old strands. While 'reading' enzymes add the complementary base pairs, pairing up each new strand with one of the parent strands. Thus when it is finished replication, each new strand will be bonded to each old strand. there will be a 1:1 ratio of old strand to new strand, thus a 50% remain of parental strand in the new strand.
What is the new strand complementary to the old strand?
DNA strands are said to be complementary because they both match up with eachother; A with T and C with G. So if you have the strand ATGGCTA the complementary strand (the other half of the double helix) would read TACCGAT. So if you know one side of the strand then you can describe the whole.
What does semi-conservative mean regard to DNA replication?
replicated DNA is made of one old strand and one new strand.
The cellular process of creating two new DNA molecules from one original copy is called replication Which statement is the BEST description of this process?
During DNA replication, the double-stranded DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. Enzymes called DNA polymerases add nucleotides to the growing strand in a direction from 5' to 3'. The end result is two identical DNA molecules, each containing one original strand and one newly synthesized strand.
Why is DNA replication caled semiconverative?
Because when the two strands of the double helix are unwound for replication each strand acts as a template to replicate a new strand onto. So, you get four strands, two pair. One of that pair is a new strand and one of the pair is the old strand that was the template strand.
Semiconservative replication involes a template what is the template?
The template for semiconservative replication is the original DNA strand that serves as a guide for creating a new complementary strand. During DNA replication, each original parental strand acts as a template for the synthesis of a new daughter strand.
