Answer:
I cant answer this I need the graph and the statements
Answer:
It has increased
Explanation:
The concentration of carbon dioxide in the atmosphere has increased in the last 200 years. The extra carbon dioxide is causing an enhanced greenhouse effect greater than would happen naturally.
Answer:
D.
Anaphase away. So, this means that The tetrads are pulled apart, while the Sister Chromatids are still together.
Explanation:
7. Adenine (A), Guanine, Cytosine and Thymine are the four nitrogenous bases in DNA.
8. In DNA Cytosine always forms hydrogen bonds with guanine.
9. The sequence of nucleotides carries the genetic information of an organism.
10. The process of replication produces a new copy of an organism's genetic information which is passed on to a new cell.
11. The double-coiled shape of DNA is called a double helix
Explanation:
There are four nitrogenous bases in the DNA of an organism. Two of the bases are pyrimidines eg: Thymine and cytosine while 2 of the bases are purine bases namely adenine and guanine. The purine of one strand forms a hydrogen bond with pyrimidine of the parallel strand of DNA.
The bases are present in nucleoplasm as dNMPs and in DNA they are present as dNTPs (deoxyribonucleotide triphosphate). During replication, these dNMPS keeps on bonding with other dNMPs in the presence of ATP and as DNA Polymerase, ligase topoisomerase etc. These nucleotides form the DNA strands and they are responsible for coding proteins. The sequence of DNA is also termed as gene.
The double helix structure of DNA was given by Watson and Crick. Each strand has an alternative backbone of sugar and phosphate group. The four bases bonds with glycosidic and phosphodiester bonds with sugar and phosphoric acid.
Answer:
they all have different charges
protons-positive
neutrons-neutral
electrons-negative
