These proteins allow substances to enter that wouldn't be able to otherwise. Only small hydrophobic substances can enter cells. However, these proteins aid crucial substsances in entering the cell.<span />
Answer:
The correct answer is - 20000, 25,000 genes.
Explanation:
Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.
According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.
Thus, the correct answer is - 20000, 25,000 genes.
Question 1 - 100%
* I need to know what the crosses are for questions 2-5
Telomerase is involved in adding DNA to the end of the lagging strand.
At the ends of linear chromosomes (telomeres), telomerase uses its built-in RNA template to extend the parent DNA template near the end of the lagging strand, providing room for an RNA primer so that lagging strand synthesis can be completed to the end of the chromosome
