Concept 1
Place the components in order, from largest to smallest.
1. Chromosome 2. DNA nucleotide 3. Codon 4. Gene
What is Chromosome,gene,codon,DNA nucleotide?
The cellular process of creating two new DNA molecules from one original copy is called?
What is replication?
This event takes place during metaphase I of meiosis.
What is homologous chromosome pairs line up in middle of cell.
Unwinds DNA.
What is helicase?
Central dogma of genetics.
What is DNA to RNA to Protein?
The main difference between the four nucleotides that make up DNA is that they have different
What is their bases?
During DNA replication the cell copies its DNA one _____ at a time.
What is nucleotide?
In this phase homologous pairs of chromosomes "crossover" and exchange genetic information.
What is prophase 1?
Humans' somatic cells contain this number of chromosomes.
What is 46?
What is it may carry the wrong instructions to the ribosome, and may result in the wrong polypeptide being made in translation.
In eukaryotes, where does DNA replication take place?
Where is the nucleus?
The number of RNA primer that is used to synthesize the leading strand of DNA during replication is?
What is 1 RNA primer?
An organism has 50 chromosomes in his sperm cell. How many chromosomes would be in his liver cells?
What is 100?
Seals final strands together.
What is ligase?
If the mRNA strand has the codon “AUG” what two things (be specific) would you expect to find on the corresponding tRNA?
What is Amino acid = Methionine on one end Anticodon = UAC on the other end?
The type of bonds present between the bases of nucleotide in DNA molecule.
What is hydrogen?
Purines are big bases ; the bases are?
What are G and A?
Two similar chromosomes that you inherit from your parents (one from your mother and one from your father) are called this long word.
What is homologous chromosome?
Brings in RNA primers to get replication started.
What is Primase?
How mRNA is modified after transcription.
What is the RNA splicing; remove the introns and the exons leave the nucleus after rejoining?
A portion of DNA, known as a(n) ________, is responsible for the inheritance of a trait, like height.
What is gene?
Pyrimidines are small bases ; what are these bases?
What is C and T?
The event takes place during anaphase II of meiosis.
What is sister chromatids separate?
Brings complementary DNA base pairs, replaces RNA primers, and proofreads.
What is DNA polymerase?
Main steps of translation.
What are
1.mRNA attaches to the ribosome.
2.Ribosome reads mRNA 1 codon at a time, starting at AUG.
3. tRNA brings corresponding amino acids( which are linked together with peptide bonds. Keeps going until a "stop" codon is reached and the completed polypeptide is released to be folded.)?
