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
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
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
How many strands of DNA are there in a DNA fingerprint?
1 strand of naked genomic DNA cut by certain enzymes.
What does semi conservation mean in terms of DNA replication?
Semi-conservative replication means that when DNA replicates, each new DNA molecule contains one strand from the original DNA molecule and one newly synthesized strand. This process helps maintain the accuracy of genetic information during cell division.
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.
Why is RNA only synthesized from one strand of a double-stranded DNA helix?
RNA is synthesized from one strand of DNA because only one of the strands contains the necessary genetic information to code for the specific protein or RNA molecule being produced. This strand, called the template strand, is used by RNA polymerase to synthesize complementary RNA strands. The other strand, known as the non-template or coding strand, is not used as a template for RNA synthesis.
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?
DNA replication is semiconservative because each new double helix contains (1) old and (1) new strand. each mother strand serves as a template for a new strand.The two strands are complementary, but not identical.
When DNA replicates what are the new DNA made of?
During DNA replication, the new DNA strands are made of nucleotides. These nucleotides consist of a phosphate group, a sugar molecule (deoxyribose), and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The nucleotides form complementary base pairs with the existing DNA strands to create two identical copies.
What holds DNA strands apart during replication?
During DNA replication, an enzyme called DNA helicase is responsible for unwinding the double helix structure of DNA, separating the two strands. Single-strand binding proteins then help to stabilize the separated strands and prevent them from reannealing.
HOW MANY STRANDS MAKES UP AN RNA MOLECULE?
Just 1 strand. DNA has 2.
What is the DNA pattern for a nucleotide?
a nucleotide is simply what the entire DNA strand is made of it contains the folloowing 1 sugar 1 phosphate 1 base either (adenine, thymine, cytosine or gaunine)
