Question

Anyone wanna help me with an essay on DNA?

Answer 1

I can help

Answer 2

Okay hold on I'll post the question @Somy

Answer 3

I would like to help too.

Answer 4

For this assignment, you will write an essay describing the production of protein molecules through transcription and translation. Your essay should include discussions of the following:

DNA
mRNA
RNA polymerase
base pairing
transcription
translation
tRNA
rRNA
ribosomes
amino acids
protein

Answer 6

Once Rna polymerase unzips the DNA helix a segement of Dna is transcribed into Rna which is transcribed into RNA. During transcription the instructiions are written into a single strand of mRNA. This messenger RNA strand is made of bases and it contains a copy of DNa's genetic code which hasinstructions on how to build proteins. The mRNA leaves the nuclues, here the DNA is located and goes through the nuclear membrane migrating into the cytoplasm where ribosomes are located. Here through translation the mRNA with it's instructions for protein production is translated at the ribosome. The sequence of the mRNA's bases codes for amino acids which tRNA (transfer RNA) identifies and brings them in. With the codes for amino acids protein production can now begin.

Answer 7

Oops I forgot to mention rRNA, let me add that in there sorry.

Answer 8

Once Rna polymerase unzips the DNA helix a segment of Dna is transcribed into Rna which is transcribed into RNA. During transcription the instructions are written into a single strand of mRNA. This messenger RNA strand is made of bases and it contains a copy of DNa's genetic code which has instructions on how to build proteins. The mRNA leaves the nucleus, here the DNA is located and goes through the nuclear membrane migrating into the cytoplasm where ribosomes are located. Here through translation the mRNA with it's instructions for protein production is translated at the ribosome. The sequence of the mRNA's bases contain codons which code for specific amino acids. tRNA (transfer RNA) identifies what kind of amino acids are coded for by mRNA and brings them in accordingly. Amino acids are the building block for proteins. rRNA ribosomal RNA migrate from the nucleus to the cytoplasm where they combine with proteins to make ribosomes. Translation occurs at the ribosomes in the cytoplasm and all of the amino acids tRNA brings goes into the ribosome where the protein is being built.

Answer 9

hold on I need to add base pairing in the beginning when RNA transcribes the dna strand into mRNA.

Answer 10

Sorry I read through the instruction really fast and overlooked that

Answer 11

Its fine i really appreciate it

Answer 12

Once RNA polymerase unzips the DNA helix it takes a segment from one of the DNA strands, to use as its template. It adds nucleotides to this template to form a RNA molecule, using commentary bases like Thymine for Uracil. During transcription the instructions are written into a single strand of mRNA, or messenger RNA.. This messenger RNA strand is made of the nucleotide bases and it contains a copy of DNA's genetic code which has instructions on how to build proteins. The mRNA leaves the nucleus, where the DNA is located and goes through the nuclear membrane, migrating into the cytoplasm where ribosomes are located. Here, through translation the mRNA with it's instructions for protein production is translated at the ribosome. The sequence of the mRNA's bases contain codons which code for specific amino acids. tRNA o, transfer RNA identifies what kind of amino acids are coded for by mRNA and brings them in accordingly. Amino acids are the building block for proteins. rRNA, or ribosomal RNA migrate s from the nucleus, like how the Mrna strand did, to the cytoplasm where they combine with proteins to make ribosome. Translation occurs at the ribosome in the cytoplasm and all of the amino acids tRNA brings goes into the ribosome, this is where the protein is being built.

Answer 13

Thank you for the medal, that makes two for me...I just joined Open Study yesterday

Answer 14

oh wow sorry sorry

Answer 15

DNA - talk about it being a template
mRNA - transcription, talk about how DNA is changed to mRNA by RNA Polymerase using primer to start the transcription, also talk about complementarity (base pairing), A-U , C-G

Now say that after transcription is done, mRNA strand leaves the nucleus through nuclear pores
goes to cytoplasmic ribosomes or ribosomes that are attached on endoplasmic reticulum
now talk about ribosome
having small and large subunit
mRNA binds to smaller one
which then attracts the larger subunit and it comes and binds to the smaller one
now both subunits of ribosome are there
mRNA is there
and now tRNA
talk about its structure
having anticodons for specific amino acids
coming from nucleus
getting amino acid complementary to its anticodon from cytoplasm and finally going to ribosome
so it comes
checks with codons on mRNA
if anticodon matches - it leaves the amino acid it brought
and all these amino acids that get left one by one add up to a polypeptide being synthesized
and this synthesis = meaning formation of peptide bond between amino acids, is done by ribozyme (rRNA) that is in larger subunit of ribosome
ribozyme is an enzyme that is ribosome based, not protein based
for more info read this http://www.conservapedia.com/Ribozyme
This is translation

now after all amino acids are joined together by those peptide bonds- a polypeptide is formed, now it will change it shape to a specific confirmation suitable for its function, whether its primary, secondary, tertiary or quaternary structure

Answer 16

thats about it
just be creative and add some details to the way you explain
also you can add more to ribosome by explaining that it has 3 sites
A site = acceptor site where tRNA enters into translation site
P site = Peptadyl site (where the leaving of amino acid and synthesis of peptide bonds between amino acid happens
and E site = Exit, is from where tRAN leaves after leaving amino acid at P site

Answer 17

watch videos for better visualization of how the process occurs
and then write it creatively :)

Answer 18

you can start of by saying that DNA is like a book that is written in a different language which is not understood by a cell
you can say its like Chinese language written with chinese characters for me, that i dont understand
transcription is like Chinese but now written with english characters which is you do know how to read but dont know the meaning still
and translation is no finally translating of the info to the language you (cell) understands and then takes up its function that it is to carry out according to DNA instructions
