Answer:
The baby is a male?
Explanation:
Baby girls only contain XX chromosomes. While baby boys contain XY chromosomes.
Answer:
True
Explanation:
Gene expression, which involves the transcription of DNA into mRNA and the subsequent translation of mRNA into proteins, is regulated in the cell of prokaryotes i.e. it is kept under control. This regulatory process, however, is done at the TRANSCRIPTIONAL LEVEL, in prokaryotic organisms like bacteria.
DNA binding proteins called transcription factors bind to the promoter region of a gene and either facilitates/enhance the binding of RNA polymerase or inhibits its binding. The enhancers are called ACTIVATORS while the inhibitors are called REPRESSORS.
Answer:
Nucleosidase
Explanation:
DNA and RNA function as genetic material in organism and proteins are synthesized on the bases of information stored in theses nucleic acids. However as these nucleic acids molecules are present in every cell so they also need to be digested and used as energy source.
- First, the pancreatic enzymes nucleases released from pancreatic acinar cells causes the breakdown of Deoxyribonucleic acid and ribonucleic acids into nucleotides.
- These nucleotides are degraded into nucleosides by phosphatase enzyme that remove the phosphate group from a nucleotide.
- Then hydrolysis of Nucleosides into base and sugar is caused by the enzyme Nucleosidase.
Meiosis is the process of reduction of diploid cells to haploid cells and it involves two process meiosis 1 and meiosis 2.
Meiosis 1 involving the crossing over of the genetic material between the pair of chromosomes whereas meiosis 2 involves the separation of the chromosomes into sister chromatids.
