Answer: B. Speed up the chemical reaction
Explanation: Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
Answer:
The same
Explanation:
In mitosis, genetically identical daughter cells are created. In meiosis the number of chromosomes is half as many as the original cell
Answer:
D
Explanation:
Asexual reproduction (requiring one parent) forms exact copies of the parent cell. The type of cell division that produces exact copies is mitosis. Therefore the answer is D.
D looks like the oldest one because there is barley anything there. if not then I would do b
Answer:
interspersed, transposon-derived repeats, simple sequence repeats.
Explanation:
In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.
Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are mobile DNA sequences that can migrate to different regions/areas of the genome.
Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.
