What else can I help you with?
Recently scientists have discovered messenger molecules known as?
Peptides
What are first messenger molecules?
First messenger molecules are signaling molecules that bind to specific receptors on the cell surface, initiating a cascade of intracellular signaling events. Examples include hormones such as adrenaline and insulin, as well as neurotransmitters like dopamine and serotonin. By binding to their respective receptors, first messengers trigger cellular responses.
What does ribosome carry?
Ribosomes attach to messenger RNA molecules and facilitate the translation of mRNA into proteins.
What two types of Rna molecules carry the Dna Code?
Messenger Rnas and Transfer Rnas.
What type of molecule did you create when you transcribed all of the nucleotides?
When transcribing all the nucleotides in DNA, the resulting molecules are mRNA (messenger RNA) molecules. These mRNA molecules serve as the template for protein synthesis during translation.
What is the difference between first messenger and second messenger?
The first messenger is nothing but referred to the molecule that brings information upto the cell surface. Once this molecule transfers signal to cell, it is taken over by the well known second messenger to take it further to nucleus through various other signaling molecules down the cascade.
What are nucleotide segments of DNA molecules that make up genes and are expressed in the phenotype of an organism?
Genes are nucleotide segments of DNA molecules that code for specific proteins or RNA molecules. These genes are transcribed into messenger RNA (mRNA), which is then translated into proteins that ultimately determine the organism's phenotype.
Which molecules carry genetic information from one generation to the next?
They are DNA molecules. They are stored in chromosomes
What hormone gives the body extra energy?
Hormones do not themselves give any energy (they are not energy containing molecules), they are messenger molecules. The hormone that prepares the body for fight or flight is "adrenalin".
WHAT DOES During protein synthesis messengers RNA?
Messenger RNA molecules are fed through the ribosomes during protein synthesis.
Which of the class of RNA molecules carries the genetic information from the nucleus as it is needed for the construction of a protein?
Messenger RNA (mRNA) carries the genetic information from the nucleus to the ribosomes in the cytoplasm where it is translated into a protein.
Is glycogen a first messenger?
No, glycogen is not a first messenger. First messengers are extracellular signaling molecules that bind to cell surface receptors to initiate a signaling cascade within the cell. Glycogen is a storage form of glucose in animals.
