What is the main role of DNA in living organisms?
DNA carries the genetic instructions for building and maintaining all living organisms.
What does the process of transcription involve?
Transcription involves copying the DNA code into messenger RNA (mRNA) in the nucleus.
Where does translation occur in the cell?
Translation occurs in the ribosome which is located in the cytoplasm.
What is the role of mrna in protein synthesis
mrna carries genetic information from the dna to the ribosome where proteins are made.
How are amino acids related to proteins?
Amino acids are the building blocks of proteins. They are linked together in a specific order to form a protein.
Why are proteins important for living organisms?
Proteins perform crucial functions such as, speeding up reactions, (enzymes) providing (structural proteins) and regulating body process (hormones and antibodies)
What is the enzyme and what does it do?
An enzyme is a type of protein that speeds up chemical reactions in the body.
What function do cell receptors serve?
Cell receptors recieve and transmit signals from outside the cell to regulate cellular activities.
How do antibodies help the immune system?
Antibodies are proteins that identify and help to neutralize foreign substances like viruses and baceteria.
What is the sequence of steps from DNA to protein synthesis?
The sequence is
1) Transcription of DNA into mRNA
2) Translation of mRNA into amino acid sequenceF
3) Folding of amino acids into a functional protein
