what are Neurones
Neurones carry electrical signals from one part of the body to another.
There are rules when it comes to base pairing…
A always binds with what?
C always binds with what?
A pair with T
C pair with G
Which process creates genetically identical cells?
mitosis
How many cells are created from cytokinesis following meiosis?
4
The F2 generation results from self-pollination of _____ plants.
F1
he S-shaped curve of the large intestine is called
sigmoid colon.
When the cell is replicating DNA is condensed up into a ______________ to prevent damage and tangling of the DNA
chromosome
During _______, chromatin condenses into chromosomes, the nuclear envelope breaks down, and a spindle starts to form.
metaphase
True or false
The daughter cells produced by meiosis are identical to each other.
false
Assume you are investigating the inheritance of stem length in pea plants. You cross-pollinate a short-stemmed plant with a long-stemmed plant. All of the offspring have long stems. Then, you let the offspring self-pollinate. Describe the stem lengths you would expect to find in the second generation of offspring.
Punnet square T t
T TT Tt
t Tt tt
The F2 would have 75% long-stemmed plants and 25% short-stemmed plants.
what are smaller than most other cells in the body.
This allows them to get through tiny blood capillaries, so they can deliver oxygen to every part of the body.
Red blood cells are smaller than most other cells in the body.
This allows them to get through tiny blood capillaries, so they can deliver oxygen to every part of the body.
what is DNA
DNA (deoxyribose nucleic acid)- is a type of nucleic acid and is the carrier of genetic information.
true or false
Mitosis results in the production of two genetically identical daughter cells.
true
The goal of meiosis is to produce sperm or eggs, also known as _______, with half the amount of DNA as the parent cell.
Gametes
When two heterozygous parents are crossed in a dihybrid cross, what fraction of offspring will be homozygous recessive?
1/16
Who was the first person to observe a cell in 1665 using a self-designed microscope?
Robert Hooke
what is a monomer of nucleic acids?
a nucleotide
What is the stage of mitosis where the centrioles move to opposite sides and the nuclear membrane disappears?
anaphase
involves the combination of gametes from two genetically diverse parents.
sexual reproduction
If you cross a purebred pea plant with green seeds and a purebred pea plant with the dominant trait of having yellow seeds, what percent of their F1 offspring will have green seeds?
0%
Who is The father of modern genetics ?
The father of modern genetics is Gregor Mendel (Gregor Johann Mendel).
A nucleotide is composed of 3 major parts
A nitrogen base
A phosphate group
A pentose sugar
how many phases are there? and what are them?
6 intrphase,metaphase, anaphase, telophase, prophase, and cytokensis
The number of chromosomes in a horse’s gamete cells is 32. How many chromosomes are present in a horse’s somatic (non-gamete) cells before meiosis and interphase?
64
When Mendel cross-pollinated purple-flowered and white-flowered parent plants, what did he observe?
White-flowered plants disappeared in the F1 generation.
