Answer:

The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

Explanation:

The genotype of F1 progeny  is AaZz

The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"

Thus, total four allele pairs will be formed.

First allele pair would be - AZ

Second allele pair would be - Az

Third allele pair would be - aZ

Fourth allele pair would be - az

Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

DNA, in the nucleus carries the genetic code for making proteins in ribosomes. In the diagram, B, represents the proteins produc
soldi70 [24.7K]

A: ribosome  C: translation

During transcription, the two DNA strands unwind and separate. Free ribonucleotides combine to the corresponding bases in the template strand, which is one of the separated DNA strands. These ribonucleotides will form a mRNA, which can leave the nucleus and enter the cytoplasm.

In cytoplasm, mRNA will be translated into protein by ribosomes. During translation, the mRNA inside the ribosome will be attached to tRNA molecules, which will then attract specific amino acids. Different tRNA molecules bond with the corresponding segments of the mRNA and different amino acids will be joining together by peptide bond. A protein is then produced.
