difference between DNA and rDNA?

Question

structure of DNA and RNA?
define genetic-engineering?
describe the importance of protein sequencing?
how the information is transformed through genes?
how new enzymes are produced?

Answer 1

Is this your homework?

All i can say is that you are not going to get a full understanding of genetics on yahoo answers.

DNA is deoxyribonucleic acid, rDNA is recombinant, so a mixture of inserted DNA normally found in retro viruses.

RNA has an oxygen on carbon 2 whereas DNA doesnt.

I truely believe that you need to go and see a speacialist in genetics to get the full picture.

Most lecturers are happy to go through it, as with most of them it is their lives.

It is a great subject and would be a waste if you only looked at it via yahoo answers.

Answer 2

Can't answer it all, but google the structures. Here are the full names:
DNA- deoxyribonucleic acid
RNA-ribonucleic acid.

A good way to think of these two nucleic acid types is that DNA is the storage form of our information, and RNA is the "working draft.". The same DNA sequence is found in all of our cells, and it never changes in a "normal" situation. RNA is like the working form, meaning DNA is transcribed into RNA, and then RNA is copied, cut, rearranged in different ways. It is then translated into proteins, which are the work horses of the cells-- they actually do the jobs, whereas DNA and RNA code for the information to make the proteins. Your body doesn't want to make mutations or in any way mess up the critical DNA information, so RNA is made as a kind of "working draft" used to make the proteins.

Genetic engineering can be defined as the ability to manipulate DNA with precision in a test tube or an organism.

Answer 3

Structure of DNA vs RNA:
DNA is a double-helix (two strands that are antiparallel and complimentary to each other). The substituents of DNA are sugar (deoxyribose), phosphate groups, and four nitrogenous bases - Thymine, Adenine, Guanine, and Cytosine. Each strand consists of many phosphodiester bonds, and the two strands are held together by Hydrogen bonds.

RNA is single-stranded. It's substituents are sugar (ribose), phosphate groups, and four nitrogenous bases (Adenine, Uracil, Guanine, and Cytosine.) It is antiparallel and complimentary to the DNA strand it replicates, however instead of using Thymine to compliment the Adenine it uses Uracil.


Genetic engineering:
Like someone said previously:
Genetic engineering is the process of manipulating genes, usually outside the organism's natural reproductive process.


Protein sequencing
Proteins are made up of three nitrogenous bases, in a particular order. If that order is switched or shifted, then it won't be the same protein anymore (unless you get really lucky!)


How information is transformed through genes
First, DNA is transcribed into RNA. Then, the RNA is translated into amino acid "language". From there, it becomes a protein. These proteins receive a "marker" and travel to the area they need to in order to fulfill their function.

How new enzymes are produced
These proteins that were just created work together in different ways to form different and new enzymes.

Answer 4

RNA has a single helix and DNA has a Double Helix. RNA also has one more Oxygen than DNA (hence the name DE-OXYribo Nucleic Acid).

Sorry - Can't help you with the gene stuff....

Protein sequencing is crucial in order for the protein to perform its proper function.

Again - gene stuff.... and I can't really tell you how enzymes are produced. Just that they are proteins, and proteins are constructed by linking amino acids together.

Hope this helped!

Answer 5

Both DNA and RNA are composed of repeating units of nucleotides. Each
nucleotide consists of a sugar, a phosphate and a nucleic acid base.
The sugar in DNA is deoxyribose. The sugar in RNA is ribose, the same
as deoxyribose but with one more OH (oxygen-hydrogen atom combination
called a hydroxyl). This is the biggest difference between DNA and RNA.
Another difference is that RNA molecules can have a much greater variety
of nucleic acid bases. DNA has mostly just 4 different bases with a few
extra occasionally. The difference in these bases (between DNA and RNA)
allows RNA molecules to assume a wide variety of shapes and also many
different functions. DNA, on the other hand, serves as a set of directions
and that's about all (but that's absolutely necessary!).

Answer 6

The first two questions:

DNA is 2 stranded, has deoxyribose as a sugar, and has the bases adenine, guanine, cytosine, and thymine.
RNA is 1 stranded, has ribose as a sugar, and has the bases adenine, guanine, cytosine, and uracil.

Genetic engineering is the process of manipulating genes, usually outside the organism's natural reproductive process.

Answer 7

DNA and RNA are essencially the same, except for RNA has one more alcohol group (OH).

RNA and DNA have the same bases, except for T in DNA and U in RNA

Good Luck

Answer 9

there carried in differnt ways

I would know if i paid more atention in biology.....
