Answer 2

its not really that i keep failing it cause i sux at putting all the info together i just need and want help i need to pass this

Answer 3

Here's a good animation that has pretty much all of this.

Answer 5

it it going to help me with the writing and putting it all together fo me? and thank uyall for yalls help

Answer 6

U r always welcome

Answer 7

like i have to much info i have everything i need but its to much and idk how to put it into a essay

Answer 8

Is this a college class that you have to do it for? Or is it for an AP class in heigh school?

Answer 9

a regular biology class in high school but its hard cause i have no help im homeschooled and the teachers never answer there phones

Answer 10

Really sad thing.

Answer 11

ya they only do monthly calls n if they want they will answer the phone so i have no help and my paretn told me to get on here so i can get help n my work done so i can pass n there sending me back to public school next year

Answer 12

Can u and or change this plzzz copy n paste it n fix it :/

Protein synthesis is the synthesis of polypeptide chains which then produce the specific proteins based on the genetic code in DNA. It occurs in two stages, transcription and translation. Transciption occurs in the nucleus. DNA contains the cistrons/genes which code for specific polypeptides. The part of the strand that forms the cistron is called the transcribing strand. It acts as a template and is transcribed to mRNA. The complementary strand which does not carry the cistron is called the non-transcribing strand. An enzyme RNA polymerase attaches itself to the promoter site next to the cistron on the DNA and initiates transcription. The enzymes moves along the particular DNA section in the 3' to 5' direction. Nucleotides from nucleoplasm with bases complementary to the beses on DNA are added one at a time to elongate the strand. Base pairing occurs. For example, base adenine on DNA pairs with uracil nucleotide and base cytosine will pairs with guanine nucleotide. Translation is the process in which the codons in mRNA are used to assemble amino acids in the correct sequence to produce a polypeptide chain. mRNA binds to the binding site on the smaller ribosomal subunit. tRNA carries amino acid to the ribosome. Cells posses more than 20 types of tRNA, more than enough for the different amino acids. The codon of mRNA forms hydrogen bonds with the anticodon of tRNA. The tRNA detaches itself from mRNA and returns to the cytoplasm to take up more amino acids. Once aligned, peptide bonds are formed between adjacent amino acids, eventually forming a polypeptide chain. rRNA consists of a single polynucleotide strand synthesised in the nucleus. The rRNA form aggregates which proteins to form the large subunit and small subunit. The subunits leave the nucleus via nuclear pore into the cytoplasm. The subunits combine to form a ribosome.

Answer 13

http://www.johnkyrk.com/ use this every step i explained ..

Answer 14

im confused on what u r having me do i wrote my thing but it needs fixing

Answer 15

i knw here in the link there is step first replication then transcription and translation if u ll see video what ever there is happening they also write it use it as a note ok

Answer 16

I'm fixing it mak, give me a few minutes.

Answer 17

thank u sooo much

Answer 18

I think it would be best to split up the the essay in 2 paragraphs, one for transcription and one for translation.

Answer 19

Here's the first paragraph on transcription that I modified, how is it?

Protein synthesis is the production of polypeptide based on a certain region of the genetic code in DNA. It occurs in two stages, transcription, which takes place in the nucleus, and translation, which takes place in the cytoplasm. Transcription is similar to DNA replication in that a single DNA strand is used as a template to synthesize a strand of RNA. In the beginning of transcription, the enzyme RNA polymerase recognizes a specific base sequence that codes for the protein of interest in the DNA called a promoter and binds to it. Next, base pairing occurs where the enzyme unwinds the DNA and assembles bases that are complementary to the DNA strand being copied. For example, if the DNA strand contains the bases GCTGCG, RNA polymerase would create a strand that contained the bases CGACGC. If the DNA strand contains the base adenine, the enzyme would complement it with the base uracil instead of thymine. RNA polymerase continues to move along the DNA in the 3’ to 5’ direction until it reaches the termination code. In eukaryotic cells, the newly-formed mRNA transcript must be further modified before it can be used. A cap is added to the 5’ end and a poly-A tail (150 to 200 adenines) is added to the 3’end of the molecule.

Answer 20

thats great thank u soo much

Answer 21

Alright, I'm editing the translation paragraph now. I'll need some more time because I'm eating breakfast atm and I'm working slowly.

Answer 22

its fine so i just delete what i have n put that n then add the second part next and thank u again i sux at this

Translation is the process in which ribosomes synthesize proteins using the mRNA transcript produced during transcription. At first, the mRNA binds with a ribosome so that it can be decoded one codon (three nucleotides) at a time. Each codon codes for an amino acid and so when each codon is read, a corresponding amino acid is activated. A tRNA molecule has two ends: one that has a specific binding site for a particular amino acid and another that has a particular sequence of nucleotides, an anticodon that can base pair with a codon. Appropriate tRNA molecules attach to and carry the activated amino acid to the ribosome. Anticodons pair with codons to bring the specific amino acid to the correct place. A second tRNA repeats this process and the first tRNA releases its amino to the second tRNA. The two amino acids form a peptide bond using the energy from ATP. The ribosome reads the next codon and another tRNA comes along to repeat the process. As tRNA come and go, amino acids link together, forming more peptide bonds. Eventually, a polypeptide chain is synthesized and it undergoes its conformational changes to carry out its function as a protein.

Answer 24

How's that? :D
