Which cells do not contain a nucleis?
Prokaryote
Do atomic nucleis have a neutral charge?
No, they have a positive charge, due to the protons.
Is bounded by a double membrane with pores and contains the cell's genetic material?
The mitochondria and the chloroplast.
Where would you find the genetic material in a cell?
A cells nucleus, mitochondria or a chloroplast may contain the DNA.
What organelle conducts respiration for the cell?
Many may think that it is the nucleis. WRONG ! It is the Mitochandria, also pronounced or said as Mitochandrian. This is because this organelle is the power house for a cell. Meaning energy for the cell is given through the Mitochandria. Respiration also carries out through this.( Take a 5th / 7th grade course and you will understand more.)
How do you measure very long half-lives?
You cannot measure it, you suppose that the decay law works all the time. Then using the half-life definition (the time which you have to wait to get half of all nucleis decayed) just put all your data in the formula and calculate what you need. The decay all was checked for not too long periods of time. And people suppose that it works for long times also. It's no reason based on multiple experiments to think that something is wrong with this law.
What roles do enzymes play in DNA replication?
When DNA strands are separated by the enzyme helicase, one of the two strands become the template i.e. free nucleotides from the cytoplasm forming the mRNA runs along this strand and reads the triplet codes by complementary base pairing. The resulting triplet codons of the mRNA, then goes to determine the anticodons and hence amino acid sequencing. Therefore the DNA is responsible for imparting the information for the amino acids to be formed and their sequence, and hence the type of protein.DNA, is a genetic material present inside the nucleus which has the information that helps in the synthesis of RNA and proteins. They have information which help in the formation of mRNA that specifies a particular protein product. mRNA acts as a template translating DNA code into specific protein. Thus DNA indirectly participates in protein synthesis by taking place in the RNA synthesisA section of DNA that codes for a given protein is copied (transcripted) onto a mRNA molecule which travels out to a ribosome where translation occurs.
