DNA needs to replicate before cells divide to give the complete set of genetic instructions to its daughter cells, (or ensures that each new cell inherits all of the genetic traits of the parent cell).
Hope this helps! :D

Answer:
Threonine
Explanation:
Using the amino acid chart, the mRNA strand ACU corresponds to the amino acid Threonine.
Red-green color blindness is due to a mutant gene in the X chromosome. An XX female with normal color vision and an XY male with normal color vision have a child with karyotype XXY who is color blind. The likely explanation is that the:_--------.
father was heterozygous for the color-blindness mutation.
mother was heterozygous for the color-blind mutation.
father had CNV of the color-blind mutation.
mother had CNV of the color-blind mutation.
None of the other answer options is correct.
Answer:
mother was heterozygous for the color-blind mutation.
Explanation:
Colorblindness is a recessive disorder. This means that it is expressed only in homozygous genotypes. The responsible gene is present on the X chromosomes. A colorblind female would have the genotype X^cX^c where c is the recessive allele of the gene present on the X chromosome responsible for color blindness. A female with genotype X^cX would have normal visible but would serve as a carrier.
Both the female and the male have normal genotype. Since they had a colorblind child, it means that the female was a heterozygous carrier for the trait and imparted the responsible allele to the child. The male can not serve as a carrier for X linked recessive disorder since they have only one copy of the X chromosome. Therefore, the female was a heterozygous carrier.
Because in DNA there are genes and most of those genes produce proteins.
Answer:
carbon dioxide &water
Explanation:
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
