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 |
