Channel protein; allows a specific molecule to pass.
Each one of the DNA base triplet is transcribed as a complementary sequence of three nucleotides , which known as a codon. A codon is a series of three nucleotides. When together, they form a unit of genetic code either in a DNA or RNA molecule.
Answer:
Yes, <em>the random alignment of the tetrads along with the equatorial plate occurs during metaphase I.</em>
Explanation:
After the crossing-over in prophase I, and during metaphase I, fibers of the <em>spindle apparatus</em> capture chromosomes and <em>take them toward the center of the cell, to the </em><u><em>metaphase plate.</em></u><em> </em>The homologous pairs of chromosomes get aligned in the metaphase plate for their posterior separation in <u>anaphase I.</u>
<em>Each chromosome of the pair joins with a microtubule of only one of the spindle poles</em>, so the two equivalent chromosomes join the fibers of opposites poles.
When they align in the center of the cell, their orientation is random.
Answer:
the number of limbs they have
Explanation:
Because you can not change the way they breathe because it is natural
You can not change the structure of the cell because it is also natural
You cannot change their sensitivity of their smell because it is also natural
so the answer is Abecause that one is a physical change that can be passed from generation
