When does the UL ratio becomes 1 to1?
The UL ratio becomes 1:1 by the age of 10 years.
What is the effect of multiplying an integer by - 1?
It becomes the negative of itself. for example -1 times 5 becomes -5
If you divide a radius of a circle by 2 what will happen to the area?
If the radius of a circle becomes 1/2 as long, the area becomes 1/4 as much.
What does it mean for a negative to be decreased by a negative?
It becomes less negative To explain. Lets take a negative, eg -5. If we decrease it by 1, it becomes -6 (where 1 is positive) Thus if we decrease it by -1, it becomes -4 (as the -1 is negative) Note that the final number could be positive, For example, if you decrease -5 by -6, you get +1
What is 2k x k?
It becomes: 2k squared
What does semi conservation mean in terms of DNA replication?
DNA Replication is semi-conservative because each DNA molecule is composed of 1 old strand and 1 new strand
During DNA replication each strand of DNA is used as a template to produce a complementary strand of DNA. This process is shown below. Which base will attach to location 1?
Guanine
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
How many strands of DNA are there in a DNA fingerprint?
1 strand of naked genomic DNA cut by certain enzymes.
The results of gel electrophoresis are shown below. What can you determine about the DNA from looking at the results of this test?
Strand 4 is the largest-Apex
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.
The results of gel electrophoresis are shown below with four different strands of DNA labeled. Which strand of DNA is the shortest?

Why is DNA replication considered semiconservative?
It is known as SEMI-CONSERVATIVE REPLICATION because the DNA produces two copies of DNA that each contain the original strand and one entirely new strand. You can definitely compare this to complementary base pairing. Hope this helps :) ~T.K
Difference between Meiosis 1 and 2?
In meiosis 1, the chromosomes were double strand while in meiosis 2, it is single strand.
HOW MANY STRANDS MAKES UP AN RNA MOLECULE?
Just 1 strand. DNA has 2.
What holds DNA strands apart during replication?
What prevents the wrong nucleotide from being added to the new strand during DNA replication? DNA polymerase 3 and DNA polymerase 1 can become what is known as exonucleases. an exonuclease can go back and "proofread" the replicated DNA and if there is a mistake, then everything beyond that incorrect nucleotide is removed and the DNA polymerase 3 will re-replicate from the bad point on. the protein p53 holds the cell in the G1 and S phase of replication which allows more time for proof reading the replicated DNA
Number of strands on the DNA molecule?
each strand in the DNA molecule has a gap of 3.4 angstrom(Ao) between them. the total length of one series of strand or 1 DNA molecule is 34 Ao. therefore 34/3.4=10. there are 10 strands or N2 base pairs in a DNA molecule.
