Answer:
1. When DNA is duplicated from mRNA which DNA, mRNA uses a <u>U</u> nucleotide instead of T.
2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is <u>CATGACATG</u>.
Explanation:
1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.
2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.
G can transcribed to C.
C can be transcribed to G.
A can be transcribed to T.
U can be transcribed to A.
Answer:
The structures that are responsible for the movement of chromosomes to the center of the cell in metaphase is the spindle fibers, the cell attaches the centromeres to the spindle fibers to pull the sister chromatids to the center
In anaphase the sister chromatids are separated at the centromere and are pulled to the opposite poles of the cell by the spindle fibers
Explanation:
<span>Trophoblasts
Trophoblasts are cells that make up the external layer of a blastocyst, this is a major source of nutrient for a newly formed organism</span>
I think the answer is
A. True
hoped that helped ;)
Answer:
The answer would be (B) because the pair of Guanine is Cytosine and the pair of Adenine is Uracil (It is paired with Thymine in DNA).
