First know the meaning of protein synthesis. Is the building or assembly, a protein molecule from amino acids. Amino acids are smaller molecules.
What are the steps of protein synthesis (how do you go to DNA to creating protein?
200
Guanine.
What type of base is the cytosine attached to on the opposite nucleotide strand?
200
The complimentary base pair rule ( A-T, G-C).
What rule is used to join the free nucleotides to the exposed bases of the DNA
200
Rosalind did the most of the research.
Who did much of the research?
300
Adenine, guanine, thymine, and cytosine
Name the four nitrogen bases?
300
A nucleotide of DNA is the base unit
A nucleotide consists of a phosphate base
(A,T,C, & G)
What is the DNA structure?
300
Three
How many hydrogen bonds connect the two bases?
300
During replication, half the original molecule is kept and the other half is synthesized from free nucleotides.
Explain why DNA replication is called semi-conservative?
300
Genes made up the DNA.
What do genes actually do?
400
Nitrogen base.
What part's of the nucleotides make up the rungs of the 'ladder?
400
The message of RNA leaves the nucleus and attention to ribose
M-RNA-Ribose
RNA is single stranded and act as a code for proteins synthesis.
What does the RNA do?
400
A pairs with T and C pairs with G.
How are bases arranged in the ladder model of DNA?
400
One-half of the original molecule is kept and the new strand is made from free nucleotides, which can only join according to the complementary base pair rule.
How does semi-conservative replication help prevent mutations during DNA replication?
400
12 or 15 years no more than that.
