The monomer nucleotides are made up of what?
What is nucleic acids.
Is RNA a double or single stranded nucleotide?
What is single stranded.
What is a Histone?
What is: chromosomes are DNA wound tightly around proteins.
In general each gene will code for a different what?
Process in which the cell copies the information in a gene by making complementary messenger RNA (mRNA) strands.
What is: transcription.
What is the DNA backbone made of?
What is phosphate, sugar- deoxyribose and nitrogenous base.
RNA has a backbone like DNA. What is the major difference in its makeup?
The sugar is different. It uses a Ribose.
Is there controlled gene expression in Eukaryotic cells?
What is: yes.
Proteins are responsible for the production of _____________ necessary to carry out life's processes.
What is: structures.
What is: speeds up.
DNA has 4 different base pairs, what are they?
What is adenine, guanine, thymine and cytosine.
RNA has 4 different base pairs, name those pairs.
What is adenine, guanine, cytosine and uracil.
Prokaryote DNA is found where?
What is: nucleoid region of the cell. Usually in the form of one large circular chromosome.
There are how many different amino acids?
What is: 20.
What does rRNA stand for?
What is ribosomal RNA.
What is helix.
Are the pairing rules still the same? Explain.
What is yes, because RNA uses DNA as a template.
Is there controlled gene expression in Prokaryotic cells?
What is: no.
To make a protein from the gene containing DNA, coding for that protein must first be converted into an _________ molecule.
What is: RNA.
mRNA strands produced in transcription are used to code to assemble amino acids in the correct order to form a protein.
What is: translation.
One strand beings with 5' and runs ___________. The other begins with 3' and runs _______________.
What is 3' and 5'.
In Eukaryotes where is the DNA stored?
What is: stored in membrane bound nucleus and in chromosomes.
Coding segments are called what?
What is: genes.
Different codons code for different what?
What is: amino acids.
What is DNA's full name?
What is: Deoxyribonucleic Acid.
