Golden Oldies
These code for different amino acid sequences, which can lead to differences in protein structure and function.
What are alleles?
The structural component of DNA that lies on the 5' end.
What is a phosphate group
DNA is read from 3' to 5', so RNA can be built in this way.
Hint: what ends?
What is 5' to 3'?
Sister chromatids are only present because of this process
What is DNA replication
The number and type of interactions between guanine and cytosine in a DNA helix
What are three hydrogen bonds
DNA --> RNA --> Protein describes this flow.
What is the central dogma?
They decode a RNA sequence to build an amino acid chain
What are ribosomes?
Instead of thymine, RNA has this nitrogenous base (1), which is complementary to this nitrogenous base (2)
(1) What is uracil
(2) What is adenine
This number of base codons result in one amino acid.
What are 3 codons?
Crossing over happens at this (1) phase of this (2) process
What is prophase I of meiosis
The percentage of cytosine in DNA if its adenine content is 18%
What is 32%
The start codon
What is AUG (or Met)?
Two parts:
The DNA double helix wraps around these (1) proteins to form this (2) noodle-like structures.
1. What are histones?
2. What are chromatin fibers?
The carbon on the ribose sugar that varies between DNA and RNA (1), and the functional group associated with this difference (2)
What is the 2' OH group
RNA polymerase in transcription moves down the DNA strand to form a RNA strand that is complimentary to this DNA strand.
What is the template strand?
