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.
Answer:
The Central dogma includes the replication, transcription and translation.
Explanation:
RNA polymerase; It is invloved in transcription process in which the the squence of DNA is coppied to RNA known as mRNA.
Spliceosomes; The genetic information is in non-continuous form i.e introns (non-codding sequences) are present between exons. These introns are removed by spliceosomes from pre-mRNA.
Codons; Codon is the sequence of three nucleotides on mRNA that code for specific amino acid i.e AUG for methionine.
Ribosomes; These are known as protein factory because protein synthesis take place in ribosomes.
tRNA; It brought the specific amino acids for corressponding codon on mRNA for polypeptide chain.
Answer:
Since there are fewer individuals there is less genetic variation meaning that one disease/disaster and wipe out the whole population
Explanation:
Answer:
There are all kinds of different forms of soil around the world, and they have different features. Just a side note dirt is only soil when there is fertility and life in the dirt. Darren is able to measure the mixture of, clay, silt, and sand to identify the soil sample.
