What is different concerning the DNA in bacterial cells as opposed to eukaryotic cells
o The amount of DNA present, whether the DNA is housed in a nucleus or not, and whether the DNA is linear or circular
• Which of these statements is true regarding cell division in the body of a growing teenaged human?
o Only a subset of cells is dividing at this point o We grow by cell division, but not all of our cells are dividing
• Dividing cells must copy their DNA
( replication ), segregate DNA and other cellular components during
( mitosis ) and split apart during
( cytokinesis)
• Our chromosomes exist as many sets of similar pairs with the EXCEPTION of our sex chromosomes o the sex chromosomes of the human female are also pairs. It is the X and Y of the male that break this rule •
Answer:
1. When DNA is duplicated from mRNA which DNA, mRNA uses a <u>U</u> nucleotide instead of T.
2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is <u>CATGACATG</u>.
Explanation:
1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.
2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.
G can transcribed to C.
C can be transcribed to G.
A can be transcribed to T.
U can be transcribed to A.
Explanation:
Latent prints are formed when the body’s natural oils and sweat on the skin are deposited onto another surface. For example if you put your thumb on your glass you will see that the oils will put your fingerprint there
Answer:
B
Explanation:
The Ames test is a bacteriological technique commonly used to determine if a particular chemical or substance can cause mutations. To achieve this, researchers use bacteria (commonly <em>Salmonella typhimurium</em>) as this bacteria strain is unable to grow in a medium that does not contain histidine (a very important amino acid in the biosynthesis of proteins). If the studied substance is able to cause mutations, bacteria will mutate, and they will be able to grow on that particular media even if they don’t have histidine for their metabolism. Therefore, if there are colonies growing, the chemical being tested is mutagenic.
I hope this clarify your inquiry.
