|---|---|---|---|---|---|
| A DNA strand has this sequence of nucleotides: guanine, cytosine, adenine, adenine, thymine, guanine. What will the mRNA sequence be? | Cytosine, guanine, uracil, uracil, adenine, cytosine
🗑
|
||||
| A DNA strand has this sequence of nucleotides: G C A A T G. How many amino acids will the mRNA code for? | Two amino acids
🗑
|
||||
| A DNA strand has this sequence of nucleotides: G C T G C A. How many codons will the mRNA have? | Two codons
🗑
|
||||
| A DNA strand has this sequence of nucleotides: G C A A T G. What are the anticodons on the tRNAs that will bond to the mRNA? | G C A A U G
🗑
|
||||
| The process of protein synthesis from DNA to RNA is called what? | Transcription
🗑
|
||||
| The process of protein synthesis from RNA to protein is called what? | Translation
🗑
|
||||
| An RNA strand has an anticodon. Is it tRNA or mRNA? | tRNA
🗑
|
||||
| Protein synthesis is occurring in a ribosome. Is this a part of transcription or translation? | Translation
🗑
|
||||
| If you look under a microscope and see distinct chromosomes in a cell, is the cell in interphase? Why or why not? | Not interphase. Chromosomes only pack into their condensed form during reproduction.
🗑
|
||||
| List in order the four stages of mitosis. | Prophase, metaphase, anaphase, telophase
🗑
|
||||
| Be able to identify the stages of mitosis in pictures. | Did you look it up?
🗑
|
||||
| The diploid number of a cell is 18. What is its haploid number? | 9
🗑
|
||||
| The haploid number of a cell is 15. What is its diploid number? | 30
🗑
|
||||
| What is the difference between a gamete and a regular animal cell? | A gamete is haploid while a regular animal cell is diploid.
🗑
|
||||
| List in order the stages of meiosis. | Prophase I, metaphase I, anaphase I, telophase I, prophase II, metaphase II, anaphase II, telophase II
🗑
|
||||
| Which is closer to mitosis: meiosis I or meiosis II? | Meiosis II
🗑
|
||||
| A single cell with 9 pairs of homologous chromosomes goes through meiosis I. How many cells result at the end of meiosis I? | Two
🗑
|
||||
| A single cell with seven pairs of homologous chromosomes goes through meiosis I. How many chromosomes exist in each cell? | Seven
🗑
|
||||
| A single cell with eleven pairs of homologous chromosomes goes through meiosis I. At the end of meiosis I, are the chromosomes in each cell duplicated or not? | Yes. The duplicates will be divided in meiosis II.
🗑
|
||||
| Five cells that originally had six pairs of homologous chromosomes go through meiosis II. How many cells result? How many total chromosomes exist in each cell? Are the cells duplicated? | Ten cells result. Six chromosomes in each cell. None are duplicated.
🗑
|
||||
| What are gametes produced in male animals called? | Sperm
🗑
|
||||
| What are gametes produced in female animals called? | Egg
🗑
|
||||
| How many useful gametes (from one cell) are produced in the meiosis of male animals? | Four
🗑
|
||||
| How many useful gametes (from one cell)are produced in meiosis of female animals? | One
🗑
|
||||
| What is the difference between a polar body and an egg? | A polar body is a non-functional female gamete, whereas an egg is a gamete that is large enough to function properly.
🗑
|
||||
| What is the purpose of the lytic pathway? | It is the way in which viruses reproduce, killing the host cells.
🗑
|
||||
| If a virus uses DNA as its genetic material, is it alive? Why? | No. It cannot reproduce on its own.
🗑
|
||||
| Can you take a vaccine after you contract the disease? Why? | No. Vaccines are used to build up the antibodies you need to fight the virus before it overwhelms your body.
🗑
|
||||
| Five cells that each has a diploid number of 12 go through mitosis. How many cells result and how many total chromosomes are in each cell? | Ten cells with twelve chromosomes.
🗑
|
||||
| A haploid cell with duplicated chromosomes turns into two haploid cells with no duplicated chromosomes. Did the cell go through mitosis, meiosis I, or meiosis II? | Meiosis II
🗑
|
||||
| A diploid cell with duplicated chromosomes turns into two diploid cells with no duplicated chromosomes. Did the cell go through mitosis, meiosis I, or meiosis II? | Mitosis
🗑
|
||||
| What two kinds of genetic material are found in viruses? | DNA and RNA
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
