Bacteria that entered an organism body can cause mutations by altering the gene
The answer is Nitrogen Cycle:)
Answer:
Peer Review
Explanation:
Peer review is a process where by, professionals or colleagues in a particular discipline with equal qualifications and abilities crosscheck the findings of fellow colleagues before the findings can be published. Peer review can be done in many disciplines. For example, we could have the medical, technical, and scholarly peer reviews.
Peer review is important because it helps to confirm the accuracy of findings and also provide a means to regulate the activities of scientific experts. Peer review is done anonymously, which means that the identity of those doing the review is not revealed. This would help to eliminate bias.
The term "unzipping" in the DNA replication refers to the breaking of the hydrogen bonds.
<span>In the process of DNA replication, DNA helicases
disentangle DNA at positions known as origins where synthesis will be
initiated. DNA helicases continue to uncoil the DNA creating a structure called replication fork
as they unzipped apart. The process of breaking the hydrogen bonds between the
nucleotide base pairs in double-stranded DNA needs energy. Helicases require
energy stored in an ATP molecule to break the bonds. </span>
Answer:
A. the two genes on chromosome 1 are more than 50 mu apart.
Explanation:
Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.
The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).
