Answer:
At the end of meiosis 1, double number of chromosomes are present in each cell.
Explanation:
Meiosis is a type of cell division in which a single parent cell is divided into four daughter cells. In meiosis 1, a single cell is divided into two daughter cells having double number of chromosomes. After that meiosis 2 occurs in which these two daughter cells again divided into four daughter cells having half number of chromosome. This type of cell division only occurs in the sex cells.
They are neither, they do not have the mechanism to ingest or produce food.
Answer:
Non-coding regions
Explanation:
Genes are segments of DNA that undergoes expression into functional products called PROTEIN. However, these genes contain both the parts or regions that encode proteins and those that don't. The part that encodes proteins are called coding sequences while those that don't encode proteins, which make up the bulk of the gene are called Non-coding regions.
When a gene undergoes expression, it is first transcibed into an RNA molecule, then translated into proteins. The coding regions of the gene will be translated while the non-coding regions will be spliced out
(introns) post-transcriptionn or be used to make RNA.
DNA polymerase checks DNA for errors. DNA polymerase checks DNA for errors by breaking the hydrogen bonds between the paired nitrogen bases in the DNA molecule. This causes the molecule to separate into two individual strands.
Answer:
Cell Junctions help in moving up a level in the hierarchy of organization of living systems. When cell junctions from, the system goes from the cell level to the _tissue_ level.
