Chromosomes are Inherited From Your Parents. One chromosome from each of your 23 pairs came from each of your parents. The two chromosomes of a pair (except for the sex chromosomes) contain the same genes, but the genes have small differences. Things like SNPs make each copy of a gene uniquely Mom's or Dad's.
Answer:
answer is 2 for both cuz they both have the 2 subscript next to hydrogen
The main benefit of crossing over is that it increases genetic diversity.
<h2>
Crossing over and
Genetic Diversity</h2>
Crossing over ensures that the daughter cells produced are genetically more diverse than their parent cells.
The exchange of chromosomal segments makes the chromosomes of the daughter cells to be more sophisticated than that of their parents.
Increased genetic diversity in daughter cells increases their chances of survival as more genes are present in their genomes that could potentially make them more adaptable to the environment.
In summary, crossing over increases genetic diversity and genetic diversity increases the chances of survival in the face of changing environment.

2. RNA synthesis complexes containing DNA, RNA, and polymerase are called ___transcription bubbles___________.
3. RNA synthesis (tRNA, mRNA, and rRNA) in general is called _______transcription_______.
4. The expression of beta-galactosidase requires the induction of operons by removal of _repressors_____________.
5. Unlike DNA synthesis, RNA synthesis does not require ___primers___________.
6. ___consensus sequences___________ are deduced by comparing many related DNA sequences.
Answer:
An Enhancer
Explanation:
Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.
According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.
