What is the function of Mitosis?
|
The function of mitosis is to equally divide replicated chromosomes into daughter cells.
|
|
How many daughter cells are produced from mitosis?
|
Two daughter cells are produced from each parent cell.
|
|
What types of cells does mitosis it produce?
|
Mitosis produces body cells such as muscle, liver, or skin cells.
|
|
How does the chromosome number of the parent cell compare to the daughter cells in mitosis?
|
The daughter cells have exactly the same number of chromosomes as the parent cell.
|
|
What is the meiosis?
|
The function of meiosis is to create haploid cells for sexual reproduction
|
|
How many daughter cells are produced from meosis?
|
Four daughter cells are produced from each parent cell
|
|
What types of cells does meiosis produce?
|
Meiosis produces gametes (sperm and egg cells).
|
|
How does the chromosome number of the parent cell compare to the daughter cells in meiosis?
|
The daughter cells havae half the number of chromosomes as the parent cell.
|
|
Who was one of the first people to scientifically study patterns of heredity?
|
Gregor Mendel
|
|
If red flowers (R) are dominant over white flowers (r) how would you represent a homozygous dominant organism?
|
RR
|
|
If red flowers (R) are dominant over white flowers (r) how would you represent a heterozygous organism?
|
Rr
|
|
If red flow flowers (R) are dominant over white flowers (r) what would the phenotype be for a flower that is Rr?
|
Red
|
|
If red flowers (R) are dominant over white flowers (r), show a Punnett square for a cross between a heterozygous flower and white flower
|
R r
r Rr rr r Rr rr |
|
Describe the difference between codominance and incomplete dominance. Give an example of each
|
In codominance, a heterozygous organism will have BOTH traits expressed. An example would be a red flower crossed with a white flower produces flowers with red and white stripes
In incomplete dominance, a heterozygous organism will show a blend somwhere between both traits. An example would be a red floer crossed with a white flower produces pink flowers. |
|
Human blood shows four different PHENOTYPES-type A, type B, Type AB, and Type O. Writed ALL of the possible genotypes for each of the four phenotypes: Which types are co-dominant? Which type is recessive
|
Type A- IaIa or Ia i
Type B- IbIb or Ibi Type AB- IaIb Type O- ii Type A and B are co-dominant Type O is recessive |
|
What is the difference between SEXUAL reproduction and ASEXUAL reproduction?
|
Asexual reproduction occurs through mitosis, where on parent cell forms two identical offspring.
Sexual reproduction occurs when gametes and two different parents combine to form an offspring. |
|
Asexual reproduction occurs through what?
|
mitosis
|
|
What is genetic modification?
|
When a gene from one organism is inserted into a different organism
|
|
How does DNA carry the genetic code(instructions for making proteins)?
|
In the sequence of the nitrogenous bases of the nucleoties (the A's, C's G's and T's)
|
|
Define Replication
|
When DNA acts as a template and an identical copy of the DNA molecule is made
|
|
Define Transcription
|
Wehn DNA acts as a template and a single-standed messenger RNA molecule is made (copying the genetic code from DNA)
|
|
Define Translation
|
When the mRNA code is read by the ribosome and used to create an amino acid chain (protein)
|
|
If the sequence of bases on a DNA template is A-G-T-A-C-T, what is the sequence of bases on the complemnetary strand?
|
T-C-A-T-G-A
|
|
What would the mRNA made from the template be?
|
U-C-A-U-G-A
|
|
What sequence of bases would be found on the anticodons that bind to those codons?
|
A-G-U and A-C-U
|
|
Put the followin cell components in order from smallest to largest: nucleus, cell, chromosome, nucleotide, and gene
|
Nucleotide, gene, chromosome, nucleus, cell
|
|
In codominance, a heterozygous organism will show a blend somewhere between both traits:
True or False? |
FALSE
|
|
In incomplete dominance, a heterozygous organism will have BOTH traits expressed:
True or False? |
FALSE
|
|
An example of codominance, a heterozygous organism would be a red flower crossed with a white flower produces flowers with red and white stripes:
True or False? |
True
|
|
An example of incomplete dominance, would be a red flower crossed with a white flower to produce pink flowers.
True or False? |
True
|
|
