Answer:
(c) one chromatid each of both homologs.
Explanation:
The S phase is characterized in that the chromosomes are duplicated, in this way a copy is created and this copy is united forming chromatids. In meiosis it is characterized in that the homologs are assembled. According to the exercise, the S phase was incubated using 3H, presumably the chromosomes will have a chromatid to support the 3H residues. Later when the homologs assemble, each of those homologs would have a chromatid to withstand such radioactivity.
Answer:
The following scientists have performed different experiments that were helpful in providing evidence that DNA is the genetic material. The summarize experiments are as follows-
1. Fredrick Griffith- the experiment was an experiment performed in 1928. It was one of the experiments that exhibit that bacteria can acquire through the process of transformation.
2 Oswald Avery, Maclyn McCarty, and Colin MacLeod: this experiment exhibited that DNA can transform the cell properties, and clarifying the chemical properties of the genes.
3. Alfred Hershey and Martha Chase: They determined that even the bacteriophage has a protective coat around it but the DNA that is present inside is the genetic material that has the ability to produce the progeny inside a bacterium.
4. Erwin Chargaff: He proposed tow rules which were named after him as chargaff rules. This tells that natural DNA the number of cytosines is equal to the number of guanine units and adenine to Thymine units.
The answer is - Never.
40 degrees of latitude, be it on the southern or northern part of the Earth, never gets direct sunlight throughout the year. This is due to the fact that the Earth's inclination is not that big so that the sunlight can fall directly on this latitude, in fact, the inclination of the Earth allows the sunlight to fall directly on the surface only to the lines of 23.5 degrees north and south of the Equator.
For number one the answer is Punnet square. For number two the answer is first generation and for number three the answer is TT so letter D! I hope this helps you!
The reading frame of the sequence would shift, causing a change in the amino acid sequence after that point.
Explanation:
DNA sequencing is important to apply to the human genome. It allows scientists to sequence genes and genomes. Since there is a limit to how many bases can be sequenced in one experiment, larger DNA molecules - as mentioned - have to be 'broken' into smaller fragments before they can be sequenced and re assembled. The normal allelic variant is 1600 base pairs (bp) long and contains three exons. The order of the genes in the beta-globin cluster is 5' - epsilon – gamma-G – gamma-A – delta – beta - 3'.
