The correct answer is metaphase 11. The chromosomes line up at the equator
Human reproductive cloning should not now be practiced. It is dangerous and likely to fail.
Answer:
The correct answer is D sister chromatids;centromere
Explanation:
After DNA replication during s phase or synthesis phase of interphase of the cell cycle,each chromosome has a copy and the cell that is newly formed is now 4n.
We cal these identical pairs sister chromatids and they are held together by a centromere
Answer:
<em>The offspring which carries the allele II will be homozygous dominant.</em>
Explanation:
A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets masked by the dominant trait.
A homozygous dominant trait occurs when both the alleles for the gen are dominant. A heterozygous dominant trait occurs when one allele is dominant and the other is recessive for the trait.
Hence, a homozygous dominant trait will carry the alleles II.
If a cytosine base is substituted for by a thymine base in a DNA segment during DNA replication, the sequence could code for the wrong amino acid during translation.
The change in the sequence of DNA is known as mutation.
When a base substitution occurs in the sequence of a DNA during replication, the genetic information in the region where the substitution occurred becomes compromised.
During transcription, the process of encoding genetic information on DNA into RNA, the base substituted is also transcribed along. If cytosine is substituted by thymine, adenine is transcribed instead of guanine.
During the translation of the genetic codes, the wrong amino acids might end up being translated due to the substituted base, leading to a faulty protein.
