The correct answer is: Prokaryotic DNA is much smaller than eukaryotic DNA.

The first difference between prokaryotic and eukaryotic genome is its structure and complexity: Prokaryotic cells have a small amount of DNA in the form of a single, circular chromosome located in the cytoplasm, while eukaryotic cells have a nucleus and DNA arranged in multiple, linear chromosomes in it; eukaryotic cell has about 25 times more DNA than a prokaryotic cell. Differences in replication between prokaryotic and eukaryotic cells:

• point of origin

• direction- replication occurs in two opposing directions in prokaryotes while in eukaryotes it is unidirectional

• polymerases- in prokaryotes there are only one or two enzymes polymerases, while in eukaryotes four or more

• faster rate in prokaryotic cells.

Answer:

In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.

Explanation:

Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.

The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.

In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

What form of pollution, if any, does each energy source cause?
lions [1.4K]
The forms of pollution that each energy source cause include air, land, water, and even space and noise pollution.
The economy influences energy source choices by the cost efficiency consideration of choosing an energy source. There must be enough money to run the energy production and maintain the energy source.
Location influences energy source choices in such a way that different locations offer different availability of different resources.<span />

valkas [14]

Answer:

The correct answer is option 3. "secondary structure".

Explanation:

The secondary structure of polypeptide and proteins refers to the second order of folding, including common structures such as beta sheets, alpha helix, as well as turns and loops. The hydrogen bonds between the oxygen and nitrogen atoms of the peptide bonds are crucial to secondary structures, as these hydrogen bonds form and stabilize the aforementioned common structures.
