Can you choose the BIO 003 CH 10?
| Question | Answer | |
|---|---|---|
| The CORRECT sequence of events occurring during transcription is ______. | initiation, elongation, termination | 80% |
| What is the smallest number of nucleotides that must be added or subtracted to change the triplet grouping of the genetic message? | one | 80% |
What is the smallest number of nucleotides that can be changed?
Three is the minimum number of nucleotides per codon needed to encode 20 amino acids. 4×4 = 16 amino acids. (i.e. 64 different combinations of four nucleotides taken three at a time).
What type of chemical bond joins the bases of complementary DNA strands?
hydrogen bonding
The hydrogen bonding between complementary bases holds the two strands of DNA together.
What contains the smallest number of nucleotides?
For comparison, the human genome has 3.2 billion nucleotides. The second smallest genome, from bacteria Tremblaya princeps, has 139,000 nucleotides. While N. deltocephalinicola has the smallest number of nucleotides, it has more protein-coding genes (137) than some bacteria.
How many nucleotides make up a codon a two B three C Four D Five?
A series of codons in part of a messenger RNA (mRNA) molecule. Each codon consists of three nucleotides, usually corresponding to a single amino acid. The nucleotides are abbreviated with the letters A, U, G and C. This is mRNA, which uses U (uracil).
What is the minimum number of nucleotide bases needed to code for this enzyme?
Three nucleotides encode an amino acid. Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids.
Which type of chemical bond joins nucleotides on one strand with the nucleotides on the complimentary strand?
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide. This produces an alternating backbone of sugar – phosphate – sugar – phosphate all along the polynucleotide chain.
