A pedigree shows the genotypes of the family members
in autosomal recessive disorders, the diseased genes are inherited from the parents. For the person to get the disease both diseased genes should be there in the genotype as its a recessive disorder.
the dominant gene - H
recessive gene - h
for a person to get a disease, genotype should be hh, as its autosomal recessive. If the person is normal he/ she could have the genotype HH or could be Hh and thats called a carrier.
the offspring will receive one gene from the mother and one from the father
Any astronomical body that revolves around a larger body is called SATELLITE. <span>There are two basic types of satellite, natural and artificial satellites. Natural satellites are those that occur naturally such as the moon and the earth while artificial satellites refers to man made satellites. Man made satellites are usually designed for collection of data and for communication. Artificial satellites have the ability to collect more information in a very short time compared to ground instruments. There are many different types of artificial satellites in space.</span><span />
Fermentation is extremely inefficient in terms of the number of ATP molecules produced for each molecule of glucose metabolized. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Answer: Precipitation
Grasslands are characterized as lands covered by grasses rather than large shrubs or trees. Grasslands are found in regions which receives rainfall that are not enough for the growth of forests. Desert covers about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Rainfall are least frequent in deserts as compared to grassland. The desert-grassland boundaries can change as a result of precipitation. The fate of land form of boundary will be dependent upon precipitation. As, if the boundary receives moderate or sufficient rainfall to grow vegetation then it will be included in the grassland and if the boundary receives no or scanty rainfall then boundary will be included in desert region.
Answer:
The bacterial DNA gets degraded at step 3 of the viral lytic cycle.
Explanation:
Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.
The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.
After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.
Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.
