Differences between eukaryotic cells and prokaryotic cells are _____.

Biology
1 answer:
topjm [15]3 years ago
6 0
The best answer is the third option namely an enclosed nucleus. One major difference between these two types of cells is that a prokaryote cell has no distinct nucleus enclosed with a membrane whereas in a eukaryote cell the genetic material, which is DNA, is packaged into chromosomes and found within a distinct nucleus that is enclosed with a membrane Examples of prokaryotes are bacteria such as staphylococcus species found as commensals on the skin of man and Streptomyces soil bacteria from which the antibiotic streptomycin is derived. Examples of eukaryotes are an amoeba, which is a unicellular protozoan that lives in water and a hepatocyte which is a liver cell in man.

What is the difference between code, codon, and anticodon?
NeX [460]
The codon is a set of 3 nucleotides that can be read to convey a message in your DNA. It can be a code saying to "start" the process of protein synthesis, or "stop" it, or to encode for an amino acid - the building blocks of proteins. 
<span>The DNA is read, and proteins are made by DNA Polymerase (simple version here, it is more complicated, but this is the gist of it) travelling down the DNA. As it travels, it reads the nucleotides and builds a chain of amino acids, that corresponds to the information gleaned from the DNA. </span>
<span>So, the codon is only on one side of the DNA, and there are 2 sides. In order to be able to keep the DNA safe, and package it well (and loads of other reasons ) there is a complimentary strand. The nucleotides that make up DNA are A, T, C, and G. A links to T and C to G, and vice versa. </span>
So if your DNA strand's codons read "AAG AGG TCA"
Then the complimentary strand will read "TTC TCC AGT" the three codons on the complimentary strand ARE THE ANTICODONS of the codons on the strand being read (aka "expressed").
<span>So a codon and an anti codon are made of the same things, it just is a matter of which is being actively expressed. Now, this gets insanely complicated when you learn more about reading frames! Not only are there those codons, but if you shift and start reading the "code" either one nucleotide earlier or later, it completely changes the message.</span>

A virus is ________ a cell.
pickupchik [31]

Answer:

smaller than

Explanation:

But they're nothing compared to the giants of the cellular world. ... And viruses are smaller again — they're about a hundredth the size of our cells. So we're about 100,000 times bigger than our cells, a million times bigger than bacteria, and 10 million times bigger than your average virus

Hope this helps <3
