How many amino acids does this DNA sequence code for TCAGCCACCTATGGA?
The DNA sequence TCAGCCACCTATGGA codes for the mRNA sequence UCAGCCACCUAUGGA, which translates to the amino acids Serine-Alanine-Threonine-Tryptophan. Therefore, this DNA sequence codes for 4 amino acids.
What is the size of the typical protein?
The typical size of a protein can vary greatly, ranging from small proteins with less than 100 amino acids to large proteins with thousands of amino acids. On average, a protein consists of about 300-400 amino acids.
What are the parts of an amino acid molecule?
An amino acid molecule consists of an amino group (NH2), a carboxyl group (COOH), a central carbon atom (α-carbon), a hydrogen atom, and a side chain (R group) that varies among different amino acids.
How are amino acids joined?
Every amino acid has 5 main parts to it, a carbon in the middle bonded to a Hydrogen, a variable group, a carboxyl group and an amine group. The important 2 for bonding are the carboxyl group which has a carbon double bonded to an Oxygen and a single bond to a hydroxyl group. The amine group is a nitrogen group bonded to 2 hydrogen. In order to bond, the amine group of one amino acid has to align with the carboxyl group of another. Then, the hydroxyl group of the carboxyl will react with a hydrogen on the amino group to release a water in a process known as dehydration synthesis. As the water gets removed, the nitrogen from the amine group bonds to the carbon in the carboxyl, completing a peptide bond between our 2 amino acids. These peptide bonds can occur at either end of an amino acid, allowing us to make long chains of daunting length. Since amino acid sequences are often so long, the structure can easily be affected by other amino acids far away in the linear chain. On the small scale, this allows for amino acid chains that either form helices or pleated sheets. On a larger scale, the chains can make complex bonding patterns that fold back, twist, turn, and allow for the basis of all life!
What is the amino acid sequence of the DNA strand 3'-taccctttagtagccact-5'?
To determine the amino acid sequence from a DNA sequence, you need to first transcribe the DNA into mRNA. Here, the mRNA sequence is 5'-AUGGGAUUUCAUCGGUGA-3'. Then you can use the genetic code to translate the mRNA into amino acids: the sequence translates to METHIONINE (Met) - GLY - PHE - HIS - ARG - STOP.
How many amino acids will be formed from a 15-nucleotide sequence?
5, this was a bio question for me at Edison community college.
How many different types of polypeptide chains can be made from 5 amino acids?
There are 5^5 (3125) different polypeptide combinations that can be made using 5 different amino acids in a chain of 5 amino acids in length. This is because there are 5 options for each amino acid position in the chain.
What is the 5 essential nutrients and the results of their deficieny?
amino acids, fatty acids, vitamins, minerals and carbohydrates
How many amino acids does this DNA sequence code for TCAGCCACCTATGGA?
The DNA sequence TCAGCCACCTATGGA codes for the mRNA sequence UCAGCCACCUAUGGA, which translates to the amino acids Serine-Alanine-Threonine-Tryptophan. Therefore, this DNA sequence codes for 4 amino acids.
No of peptide bonds in hexapeptide would be?
A hexapeptide is a peptide composed of six amino acids linked together through peptide bonds. Since each peptide bond is formed between two amino acids, a hexapeptide would have 5 peptide bonds connecting the 6 amino acids.
How many distinct pentapeptides can be made from the 20 amino acids?
There are 20 choices for the first amino acid, 20 for the second, and so on, resulting in 20^5 = 3,200,000 distinct pentapeptides that can be made from the 20 amino acids.
What is formed when 5 amino acids are joined together?
When five amino acids are joined together, a molecule called a peptide is formed. Peptides are short chains of amino acids linked by peptide bonds. As the chain grows longer, it becomes a polypeptide.
What is a 5 residue polypeptide?
Basically, proteins are long chains of amino acids, which are linked together through a chemical bond known as a peptide bond. They can be hundreds of amino acids in length. Peptides, which qualify as proteins, are just shorter chains of amino acids, generally between 2 and 100 amino acids. In biochemistry, amino acids are also referred to as residues; thus a 5 residue polypeptide is just a 5 amino acid long peptide, linked together with a peptide bond between each residue.
What are not related to the other four A. amino acids B.nucleotides c.5-carbon surgars D. phosphate E.nitrogenous bases?
C. 5-carbon sugars do not belong to the same group as amino acids, nucleotides, phosphate, and nitrogenous bases. 5-carbon sugars are components of nucleotides, which are building blocks of DNA and RNA, but they are not amino acids, phosphate, or nitrogenous bases.
What are the four amino acids?
There are 20 amino acids however our body can only manufacture 12 of these, thus eight of them we must get from our food. Therefore the 8 most important amino acids are the ones we get from our food (known as "essential amino acids"). These are: 1) Isoleucine 2) Leucine 3) Lysine 4) Methionine/ Cysteine 5) Phenylalanine/ Tyrosine- 6)Threonine 7) Tryptophan 8) Valine
Is oxygen present in amino acids?
Yes, amino acids will contain oxygen in their carboxyl group and might in its variable R group. The four types of amino acid side chains [R-groups] are i) non-polar (zero for 8) - no oxygen, ii) uncharged-polar - (5 out of 7 have oxygen), iii) charged-polar - both have oxygen, and iv) basic amino acids - zero for 3 have oxygen.
What are the 5 types of protein?
Proteins: collagen, keratin, hemoglobin, albumin, myosin, and actin. Hundreds of others.Proteins are polymers of amino acids. Amino acids have a carboxylic acid group and a amino group (amino-acid get it).Welcome!
