2026) Genetics | Questions & Answers | Grade A |
100% Correct. Portage Learning.
1. RNA pentose sugar is called:: ribose
2. nucleoside: base + sugar (missing phosphate group)
3. nucleotide: base + sugar + phosphate group
4. G binds to: C with 3 hydrogen bonds
5. A binds to: T with 2 hydrogen bonds
(or U in RNA)
6. Codon: three-nucleotide sequence on messenger RNA that codes for a
single amino acid
7. True/False:
Transcription of mRNA into DNA requires an RNA primer.: False
8. Which type of cell has more DNA-prokaryotes or eukaryotes?:
Eukaryotes 9. What happens to complexes during DNA replication?:
1/7
, BIOD210
Complexes relax due to histone proteins dissociating and when replication ends,
histone proteins tighten and DNA condenses.
10. Ribosomes: Serves as a site for protein
11.Shelterin complex: Protects chromosome ends from degradation
12.Reverse transcription: synthesis of DNA from RNA template
13.Exon: mRNA sequences that are ending
14.wobble hypothesis: the hypothesis that some tRNA molecules can pair
with more than one mRNA codon, tolerating some variations in the third
base, as long as the first and second bases are correctly matched
15.degeneracy of the genetic code: most amino acids are not specified by
a single codon
16.Pribnow element: cis-acting
17.Where is Pribnow element located?: upstream from the site of
transcription
initiation
18.True/False:
A silencer element is always located close to the gene it affects, but
an enhancer element can be located far away.: False
