Answer:
The model showing the condition must represent a recombination between the X and Y chromosome during meiosis in male.
Explanation:
In males, the sex chromosomes are X and Y, whereas, the females have XX chromosomes. When the X chromosome of males fuses with the female gamete it give rise to a female progeny.
The Sry gene is present on the Y chromosome. In some cases, the recombination between the X and Y chromosome during meiosis in males takes place and result in an X chromosome containing Sry gene. This Sry gene is responsible for the male characters and progeny carrying two X chromosomes, in which one has the Sry gene would have the male characters.
So, the in this case should represented the crossing over between the X and Y chromosomes in males and then passing of the Sry containing X chromosome to progeny.
Answer:
DNA is divided into codons which are 3 bases long. Each codon codes for a specific amino acid or signals transcription to stop or start. Inserting or deleting one base pair changes how the DNA is read, so it will often alter the amino acids the DNA sequence produces. As a result, the protein made from the gene may not function properly.
Example:
AAT CGC CGA TGA
Delete the T from the first codon
AAC GCC GAT GA
The entire sequence is read differently ^

This is what I found. So if you use this please reword it as your own.

Which step in transcription occurs first?
C. RNA polymerase attaches to the promoter.
