Answer:
a
Explanation:
Because the chromatids now contain little bits of DNA from one another they aren't identical. hope it helps
Answer:
I believe the correct answer is<em> </em><u><em>C. mRnA translation. </em></u>
Explanation:
Because the gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.
B. It has a whip, like a tail
Explanation - Protists are unicellular organisms. Some multi-cellular organism might exist. Some protists have silica plated scales on their body surface like diatomaceous earth. They exhibit both type of respiration - aerobic and anaerobic. They mainly have parasitic mode of nutrition.
Protists also have flagella which they whip that in turn helps in their movement and this feature have made them to enter into the water body, example - euglena. Paramoecium have cilia on their entire surface that helps in their locomotion in water.
Answer:
DNA is the genetic material of all the living organism except some viruses. The structure of DNA consists of nitrogenous base, pentose sugar and the phosphate group.
Tube 1 - The nucleotide are linked together by phosphodiester bond. As these bonds are broken, the structure of DNA contains the individual complementary nucleotide are linked together by hydrogen bonds.
Tube 2 - The bond between the sugar and the bases are broken. The DNA structure consists of the phosphate group chain only with any pairing with the base.
Tube 3 - The DNA nitrogenous bases are adenine, guanine, thymine and cytosine that are linked together by hydrogen bonds. The agents break the hydrogen bonds. Now, the DNA structure consists of the single strand only.
