What are the functions of RNA polymerase?
RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
What is meant by RNA?
RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses.
What are the two parts of tRNA?
The two most important parts of a tRNA are its anticodon and the terminal 3′ hydroxyl group, which can form an ester linkage with an amino acid.
What is the function of Anticodon?
Anticodons are found on molecules of tRNA. Their function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain.
What is the function of codons in RNA?
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
What are the three steps of the translation process?
Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination.
How many types of amino acids are there?
20 types
What are the 2 types of amino acids?
Amino acids are classified into three groups:
- Essential amino acids.
- Nonessential amino acids.
- Conditional amino acids.

What are the 10 essential amino acids?
Ten amino acids, namely L-arginine, L-histidine, L-isoleucine, L-leucine, L-lysine, L-methionine, L-phenylalanine, L-threonine, L-tryptophan, and L-valine, were shown to be essential for the parasite’s development.
Which amino acid is the most important?
The essential amino acids are arginine (required for the young, but not for adults), histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids are required in the diet.
What are the 7 Ionizable amino acids?
These are the 7 amino acids that have ionizable side-chains with their pKR’s. They are: R, K, Y, C, H, E, D (in order of basic/greatest pH to most acidic/lowest pH).
What are the benefits of amino acids?
Amino acids play a role in almost every system throughout your body, including:
- Assisting in the creation and growth of muscles, connective tissue, and skin.
- Assisting in maintaining muscle tone and tissue strength.
- Healing and repair.
- Normal digestion.
- Providing energy for your body.
What are the symptoms of amino acid deficiency?
Here are nine signs you have an amino acid deficiency.
- Trouble Focusing. Tyrosine is an essential amino acid found in protein-rich foods like dairy products, meat, and eggs.
- Fatigue.
- Memory Loss.
- Slow Illness Recovery.
- Muscle Loss.
- Craving Unhealthy Foods.
- Weakness.
- Depressed Mood.
