Well I’m not for sure but I think it’s false because the units can be Baer in animals too
Answer:
After every 0.192 centimorgan
Explanation:
If there are 125 million base pairs then according to the parallel ratio compare rule it should contain an average of 650 genes. If every gene has to be marked by a single marker on each end then a total number of 651 markers are used after every 0.192 centimorgan distance.
It would be D.) 450. You need to multiply the two numbers. (ex: 30*15 = 450)
Step one you should have a clean slide and coverslip, step two is you place ONE drop of water in the middle of the slide, step three place the edge of a cover slip on one side of the water drop, step four cover the slip on top of the drop at a fourty five degree angle, step five place the slide on the stage and view it at first with the red banded objective, you can rotate the nosepiece to view the slide with different objectives.
Answer: B the ends of linear chromosomes.
Explanation:
Based on structure, telomeres are located at the end of chromosomes; they are protective caps that bind the genes at the end of the chromosomes in order to prevent it from interchromosomal fusion (clumping) and degradation (broken down). Simply, they serve the same role as plastic caps to the tip of shoe laces; preventing it from unraveling.
.
Generally, telomeres becomes short in length with time. At this stage they become weaken, and breaks down. The affected the cells basic replication activites, and therefore the functions. These non-functioning cells accumulated in body organs, and made them to degenerate .This reduced longevity, leading to death of cells. However the shortening of the length is an advantage to prevent the spread of cancer in cells because I naturally stops the uncontrivable growth of cells
Therefore the longer the length of telomeres at the genome end of chromosomes, the higher the rate of replication of the concerned cells, and hence the increase in the age of the cell
