What would be the first three amino acids in the protein formed from this gene uagcgagg?
Each amino acid is coded for by a 3-base sequence known as a codon. Therefore you would need 9 bases to code for 3 amino acids.The sequence UAG-CGA-GG would not add three amino acids to a protein.For the sequence UAG-CGA-GG:UAG is a STOP codon - translation would cease at this point and no further amino acids would be added.CGA codes for Arginine.GG does not code for an amino acid - it would need one more base to be a codon. GGU, GGA, GGG and GGC all code for Glycine.
How many amino acids would be in a protein that is coded by a DNA strand ninety-nine nucleotides long?
If all the nucleotides are protein coding with no control sequences, then 33. Each amino acid is coded for by 3 nucleotide bases. 99 divided by 3 = 33.
How many water molecules were released during the synthesis of a protein that contains 500 amino acids?
The number of water molecules required is equal to the number of peptide bonds that need to be broken. In a polypeptide of 9 amino acids, there are 8 peptide bonds between them. You therefore need 8 molecules of water to hydrolyse those bonds.
What are the steps taken to translate a 9-base DNA strand into an amino acid sequence?
There are a huge number of steps involved in this process, but briefly it goes like this: # Transcription factors bind to DNA and promote binding of RNA polymerase # RNA polymerase binds in complex with transcription factors # Transcription is initiated and RNA polymerase uses free NTPs, complementary to the antisense strand of DNA to create an RNA copy of the DNA. # The mRNA leaves the nucleus - some modification may take place # Translation factors bind mRNA # Ribosome binds to mRNA # tRNA brings amino acids to ribosome # Ribosome begins translation at methionine start codon - matching anticodon on tRNA to triplet codons on mRNA to pair correct amino acid to the mRNA code # Ribosome stops translation at stop codon # Ribosome/mRNA/tripeptide complex will dissociate
Protein synthesis steps?
The major steps of protein synthesis are:1. Transcription-before a protein can be synthesized, the DNA information or code must first be copied or transcribed to a type of RNA called mRNA (messenger RNA). Bothe the codes in DNA and mRNA are carried as units called codons.2. Translation-in the ribosome, the code carried by the mRNA is translated into a sequence of amino acids that will form the protein molecule dictated by the DNA.
How many different kinds of amino acids are essential amino acids?
9
How many essential acids are necessary for good health?
There are 22 standard amino acids of which 9 are essential amino acids. The essential ones are the ones our bodies cannot produce and so need to get them from food.
How many amino acids are considered by scientists to be essential?
9
What foods contains all essential amino acids?
I believe hemp seeds contain all 9 amino-acids.
Which characteristic makes 9 amino acids essential?
The body cannot make them.
The 12 essential amino acids must be obtained from the foods you eat?
False. It's 9
What foods supply you with all the essential amino acids?
meat
There are more essential fatty acids required by the body than there are essential amino acids required by the body?
False. There are 9 essential amino acids: lysine, tryptophan, phenylalanine, threonine, valine, methionine, leucine, isoleucine, and histidine. The essential fatty acids are linoleic acid and linolenic acid. (Human Physiology Stuart Ira Fox 12th edition)
What are the 20 known amino acids?
There are actually 22 known amino acids - 9 of which are Essential. That is, they cannot be manufactured by the body. The other 13 can be manufactured as long as all 9 Essential amino acids are consumed from our food. 1. Alanine 2. Arginine 3. Asparagine 4. Aspartic acid 5. Cysteine 6. Cystine 7. Glutamine 8. Glutamic acid 9. Glycine 10. Histidine - Essential 11. Hydroxyproline 12. Isoleucine - Essential 13. Leucine - Essential 14. Lysine - Essential 15. Methionine - Essential 16. Phenylalanine - Essential 17. Proline 18. Serine 19. Threonine - Essential 20. Tryptophan - Essential 21. Tyrosine 22. Valine - Essential
How many Of the 20 amino acids relevant to the human body are considered nonessential?
There are nine amino acids that are considered essential amino acids, meaning that they cannot be synthesized by the body and must be obtained from the diet. These essential amino acids are: Histidine Isoleucine Leucine Lysine Methionine Phenylalanine Threonine Tryptophan Valine These essential amino acids are crucial for many bodily functions, including the production of proteins, neurotransmitters, and hormones. They play a key role in growth and development, immune function, and the maintenance of tissues and organs. It's important to ensure that your diet includes sources of these essential amino acids to support optimal health.

What are the 9 essential amino acids?
Eight amino acids are generally regarded as essential for humans: phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, and lysine. Cysteine (or sulphur-containing amino acids), tyrosine (or aromatic amino acids), histidine and arginine are additionally required by infants and growing children.
What is an essential amino acid?
An essential amino acid is a building block of protein molecules that our bodies cannot produce and need to get from a food source. They are essential because we can not synthesize them from other amino acids or smaller building blocks. Ultimately they are needed to make proteins which build tissues in our bodies.AnswerProtein molecules are long chains of amino acids. There are 20 naturally occurring amino acids used in protein synthesis alanine, asparagine, aspartic acid, glutamic acid, cysteine, glutamine, glycine, proline, serine, tyrosine, arginine and histidine are non essential in that they can be synthesized from precursors in the diet. The amino acids isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine can not be synthesised by the body and therefore must be essential components of the diet. However some of the nonessential amino acids listed above are essential for normal growth in children since they do not have full biosynthetic capability as they develop.AnswerAmino acids which can't be synthesized by the body and must be taken in diet are known as essential amino acids.Essential amino acids are required by animals yet they cannot be synthesized, they are usually supplied in the diet.
