What is one way DNA of prokaryotes cells differs from that of eukaryotic cells?
prokaryotic DNA is in a ring form
Way that RNA differs from DNA?
There are 3 main differences between the two (which we just went over in bio this morning!) 1) RNA contains uracil instead of thymine that pairs up with adenine. 2) Their sugars are different, RNA has ribose sugar, while DNA has deoxyribose sugar (hence their names) 3) DNA is double stranded while RNA is single stranded. Hope that is good enough!
What is one way the of prokaryotic cells differs from that of eukaryotic cells?
prokaryotic DNA is in a ring form
What enzyme unzips DNA and RNA?
the one that breaks it is called Helicase and the one that adds it is called Polymerase.
Hoes does the transfer of RNA work?
The transfer of RNA works in a similar way to DNA except that RNA does not have a "backup" or double stand of chromosomal information in the DNA material.
Why the DNA molecule differs from the RNA molecule?
RNA and DNA work together in a way despite the differences. When your DNA calls for a protein your body needs to make, RNA within a cell has the DNA separate into two 'strands', and the RNA will attach to the other half of the DNA to scan the coded 'message' made of the nitrogen bases; adenine, thymine, cytosine, and guanine in a specific pattern. This RNA is called messenger RNA. It then floats into the cytoplasm of a cell and transfers the code of a protein to a ribosome; Ribosomes create proteins. As the RNA transfers the coded protein, Transfer RNA comes in and decodes the protein, to slowly build a molecule of that protein. When the molecule is complete and the code is decoded, you get a protein or amino acid. IF YOU'RE WONDERING THE DIFFERENCES: DNA has two strands to make a twisted ladder shape. RNA is a single strand. DNA has the nitrogen bases: Adenine, Thymine, Cytosine, and Guanine RNA has: Adenine, Uracil, Cytosine, and Guanine. Adenine in DNA pairs with Thymine. Adenine in RNA pairs with Uracil instead.

How do you know if you are looking at a DNA or RNA sequence?
DNA sequences contain the nitrogen bases adenine, thymine, cytosine, and guanine. RNA sequences contain the nitrogen bases adenine, uracil, cytosine, and guanine. If the sequence contains thymine it is a DNA sequence if it contains uracil it is an RNA sequence.
Why is thymine found in Dna but not in Rna?
Thymine is found in DNA because it is more stable than uracil, which is found in RNA. Thymine can better protect genetic information from being altered by environmental factors. This provides DNA with more integrity, making it suitable for long-term storage of genetic information.
In what way is RNA different from dna?
The following distinguishing characteristics can be used to differentiate between DNA and RNA:Pentose sugar - the deoxyribose of DNA has one less oxygen than the ribose of RNANitrogenous bases - DNA contain adenine, thymine, cytosine, guanine; RNA contains adenine, uracil, cytosine, and guanine.Strandedness - DNA is double-stranded and RNA is single-stranded.Functions - DNA stores genetic information and RNA transfers the information to other places in the cell.Location - DNA is only found in the nucleus whereas RNA can be found in both the nucleus and cytoplasm. DNA contains the information for protein synthesis; RNA carries out protein synthesis.Reactivity - DNA is less reactive due to stable C-H bonds; RNA is more reactive due to C-OH bond. DNA is stable in alkaline/basic conditions while RNA is unstable in alkaline/basic conditions.UV radiation - DNA is more easily damaged.Grooves - DNA has smaller grooves reduce enzyme ability to attach and damage while RNA has large grooves enable enzymes to attach and damage.Geometry - DNA has B-form helix geometry and RNA has A-form helix geometry
What are the purposes of DNA and RNA in the body?
well DNA is wat makes u look the way u look and its wat makes u act the way u cat sorry cant say much about RNA
Why rna primer is used instead of dna primer?
There are basically two types of enzymes that can bind to DNA and copy it. The DNA polymerase and the RNA polymerase. The RNA polymerase, which copies DNA into RNA, will only bind to single stranded DNA, in other words areas of the DNA where the nitrogen bases holding the two strands of nucleotide units together have been separated. On the other hand the DNA polymerase that copies DNA into DNA will only bind to DNA that is double stranded. So in lies the dilemma. To make a copy of the DNA the DNA polymerase is use, but it will not bind to single stranded DNA so there is no way to make a DNA primer using aDNA polymerase, but the RNA polymerase will bind to single stranded DNA and there for can be used to make a small RNA primer on the open strands of DNA. Now the DNA polymerase has place that is double stranded and can attach and start copying the DNA.
