DNA
Cancer is a disorder in which some cells have lost the ability to control their
a. size. c. growth rate.
b. spindle fibers. d. surface area.
What is c?
the shape of RNA.
What is single stranded?
This is being replicated
What is DNA?
This is transcribed
What is DNA?
The end product of translation
What is an amino acid chain or protein chain?
The bonds between phosphate and sugar molecules in DNA are...
a. covalent bonds c. hydrogen bonds
b. ionic bonds d. weak bonds
What is a?
The sugar in RNA
What is ribose?
The base pair rule
What is .... A - T G - C
DNA transcribed to this
What is mRNA?
mRNA is "read" by this organelle to form a protein chain
What are ribosomes?
Replicate this sequence: ATCGCC
TAGCGG
Base that is only found in RNA
What is U - uracil?
Enzyme that adds new DNA strands
What is DNA polymerase?
The base pair rules for transcirption.
What is ... A-U T-A G-C?
What are codons and what is it made of? Be specific.
Codons are three bases made up of (A, G, C, and/or U)
What are the three components of a nucleotide?
Phosphate group, sugar, and base (A, T, C, or G)
The START codon
What is AUG?
A change in DNA sequence (like a dropped nucleotide)
What is a mutation?
Why does transcription take place?
DNA cannot leave the nucleus and therefore must be transcribed to mRNA to leave the nucleus.
Type of RNA that "brings" amino acids to the ribosome
What is tRNA?
Give one reason why DNA is essential to life.
DNA is an organism's genetic code. DNA creates genetic diversity. Contains code of essential proteins.
Number of codons needed to specify 6 amino acids
What is 6?
During DNA replication, a DNA strand that has the bases ATTCGA produces a strand with the bases ...
What is TAAGCT?
Organelle in the cell where transcription takes place
What is the nucleus?
Use page 367 in your book. Ifentify which amino acids will be translated from the following mRNA strand ... AUG CGG AAA UAG
What are Methionine - Arginine - Lysine - STOP?
