Answer:

The correct options are:

Prior to process 1, DNA should copy itself to allow the cell to divide.

Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.

Explanation:

For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.

Answer:

The offsprings of this punnet square will be Dd, Dd, dd and dd in a ratio 1Dd : 1dd

See attached image for punnet square completion

Explanation:

This question involves a cross involving a single gene with alleles D and d where allele D is dominant over allele d i.e. D will mask the phenotypic expression of d in a heterozygous state.

This cross is between a heterozygous parent (Dd) and a homozygous recessive parent (dd). Parent Dd will produce gametes D and d while parent dd will produce gametes d and d.

Using these gametes in a punnet square, four possible offsprings with two distinct genotypes will be produced. The genotypes are: Dd and dd in a ratio 1:1

Hence, the possibility of having a heterozygous dominant offspring is 1/2 while the possibility of having a homozygous recessive offspring is also 1/2.
