The first step of DNA replication is to copy part of the DNA sequence into?
mRNA
What is the red part on the end of a match called?
Dulce
Is it possible to stick a match in your nose?
Of course it's possible to stick a match up your nose, but why would anyone want to do that?Now, if you meant "strike a match inside your nose", then that sounds much more reasonable.Matches need enough friction to ignite the chemicals on the match head. It is unlikely that the mucous membranes inside your nose have enough friction. Besides...the chemicals on a match head should not come in contact with any part of your face.
Do yellow and orange go together?
For the most part, yes. You just need to make sure the two shades match.
What occurs during the process of transcription?
The genetic information stored in DNA is transcribed into messenger Rna that is then transported to the cytoplasmic Ribosomes for translation.
What is the relationship between codons and anticodons?
A codon is found in the DNA sequence and in the mRNA sequence. The anticodon is the opposite sequence that would match with the sequence of the codon and allows pairing of the anticodon with the codon
In tRNA why does the agc anticodon need to pair with a specific mRNA codon and what is the mRNA codon it pairs with?
AGC needs to be paired up with UCG (which is the specific mRNA codon) in order to transfer message from mRNA to polypeptide. In addition it is a part of process in trancription (for elongation). **Hopefully I have answered this question correctly..if not, please correct it..thanks!
What part do codons and anticodons play in translation?
tRNAanti-codonsact as the interpreters of the mRNA codon sequence
What molecule is the anti-codon found on?
A nucleotide triplet in a tRNA molecule that aligns with a particular codon in mRNA under the influence of the ribosome, so that the amino acid carried by the tRNA is added to a growing protein chain.
What is a messenger Rna code word?
I assume the word you're looking for is "codon".
Anti codons are part of the structure of?
An anticodon is a three nucleotide sequence found as part of Transfer RNA. The anticodon is the portion of the tRNA that binds to the relevant portion of the messenger RNA (mRNA). Overall, the anticodon assists in matching amino acid sequences to mRNA codon sequences during protein synthesis.
Describe the difference between a termination signal and a stop codon?
Termination signal is at the end of the part of the chromosome being transcribed during transcription of mRNA. While in a stop codon, also called termination codon, is a nucleotide triplet within messenger RNA that signals a termination of translation.
What would happen if the very last stop codon of a mRNA molecule was mutated into a regular codon?
That isn't exactly a mutation; it's more like degradation. It would basically mean that mRNA, which is made up of multiple codons, will deteriorate into a codon, which is only 3 nucleic acids combined together. Such corrosion would probably result in the cell breaking the codon like how it normally does mRNA, or it will be absorbed into the nucleus to be combined to form a normal mRNA.
Matches a cell part with it function?
You can match a cell part with its function, for example the ribosomes, can be matched with "site for mRNA translation".
What does synthesis protein mean?
= Protein Synthesis = ----Legend:Process whereby DNA encodes for the production of amino acids and proteins. This process can be divided into two parts:1. TranscriptionBefore the synthesis of a protein begins, the corresponding RNA molecule is produced by RNA transcription. One strand of the DNA double helix is used as a template by the RNA polymerase to synthesize a messenger RNA (mRNA). This mRNA migrates from the nucleus to the cytoplasm. During this step, mRNA goes through different types of maturation including one called splicingwhen the non-coding sequences are eliminated. The coding mRNA sequence can be described as a unit of three nucleotides called a codon. 2. TranslationThe ribosome binds to the mRNA at the start codon (AUG) that is recognized only by the initiator tRNA. The ribosome proceeds to the elongation phase of protein synthesis. During this stage, complexes, composed of an amino acid linked to tRNA, sequentially bind to the appropriate codon in mRNA by forming complementary base pairs with the tRNA anticodon. The ribosome moves from codon to codon along the mRNA. Amino acids are added one by one, translated into polypeptidic sequences dictated by DNA and represented by mRNA. At the end, a release factor binds to the stop codon, terminating translation and releasing the complete polypeptide from the ribosome. One specific amino acid can correspond to more than one codon. The genetic code is said to be degenerate.
How does DNA make a copy of itself in order to travel outside to make protein?
DNA is double stranded, in the shape we know as the "double helix." One strand of DNA is the coding strand, while the other is called the complementary strand. The coding strand is what has the protein codes, the complementary strand just bonds to that strand. DNA is also located inside the nucleus, which is protected by a nuclear membrane. This nuclear membrane is porus, but the double helix is too big to fit through these pores. So, the DNA has to be copied into mRNA (messenger ribonucleic acid.) Now, DNA is made up of nucleotides, all of which are either Adenine, Thymine, Guanine, and Cytosine; or just A, T, G, and C. A and T always pair together in the double helix, and G and C always pair together. But, the mRNA has ribonucleotides. There are still A, G, and C; but instead of a T bonding to an A, a Uracil, or U, will bond to all the A nucleotides. Okay, confusing basics, but heres the fun part. The DNA molecule "unzips," or the two strands pull apart when its time to make a protein. Then, a molecule called an mRNA polymerase will attach to the coding strand of the DNA and start "reading" it. Once it reaches the sequence "TAC" (remember the little parts that make up the DNA strand,) it will start to attach the ribonucleotides. This "TAC" is know as a start codon, because it tells the mRNA polymerase to start. Now, the mRNA polymerase will bond "AUG" to the "TAC". Then mRNA will continue to bond it's ribonucleotides to the corresponding nucleotides of the coding strand of DNA, until it reaches a "stop" codon. This stop codon is either ATT, ATC, or ACT on the DNA; which becomes UAA, UAG, or UGA on the mRNA. This is when the mRNA stops pairing ribonucleotides to the DNA nucleotides, because the code for the protein is complete. Every set of 3 nucleotides in between the start and stop codons are called a codon, and they code for one specific amino acid that will make up the protein. Now that the mRNA strand has been made, it is sent out of the nucleus because it is single-stranded, and can fit through the pores. This process of making the mRNA is called Transcripiton. But how can the protein be made? As soon as the mRNA strand exits the nucleus, a ribosome, or rRNA molecule, bonds to it. This ribosome "reads" the mRNA, and begins to attach "anti-codons" to the mRNA codons (remember a codon is 3 ribonucleotides that code for an amino acid.) The anti-codons and the amino acids come in a "package" called a tRNA, or transfer RNA, molecule. This consists of the anti-codon that will pair up to the mRNA codon, and an attached amino acid that is specific to the mRNA codon. For example, the start codon AUG will pair to the anti-codon UAC, and AUG codes for the amino acid methionine; so the tRNA molecule will have UAC at the base, and methionine attached at the top. The ribosome will do this to each codon within the strand, so each codon has an anti-codon and amino acid attached. But, ribosomes can only fit 3 codons inside them at any time, so it has to move down the mRNA 3 codons at a time. As a codon exits the ribosome after being attached to it's tRNA molecule, the anti-codon part of the tRNA breaks off and the amino acid attaches to the other amino acids using a peptide bond. So the ribosome leaves behind a string of amino acids bonded together using peptide bonds. To find out which codons on the mRNA code for which amino acids, you need to use an "amino acid wheel," which is a wheel that is read by looking at the innermost circle and finding the ribonucleotide that the codon begins with, then looking in that section to find the second ribonucleotide in the codon, then looking in that small section of the outermost circle to find the last ribonucleotide of the codon, which will then show you the protein. This chart is attached in the image below. Anyways, once the ribosome reaches a stop codon on the mRNA, it stops attaching the tRNA molecules, and the result is all the amino acids that correspond to the codons, bonded together to create the finished protein! This process of creating the protein is called Translation, so the entire process from DNA to protein is called Transcription and Translation.
