Tissue regeneration & repair

Tissue regeneration involves the restoration of tissue components by regrowth of damaged tissues. In contrast, tissue repair involves patching of injured tissue rather than restoring it. It is the proliferative capacity of the cells that decides the amount of regeneration against the repair that would occur in the tissue. Both regeneration and repair depending on the duration of the injury and response to the inflammation.

we done an experiment where we extracted the DNA from strawberry, grape, and peas. With the strawberries, we were able to find its DNA in the solution very easily because it was floating on the top. But for the grapes we were only able to see very small clumps which we weren't able to collect. And for the peas, we weren't able to see anything or collect any of their DNA. all I need is for help with the CER(claim, evidence, and reasoning) thank you!!
What is the difference between a transgenic plant and a plant produced through selective breeding?
Scientists carried out a microarray analysis to compare the gene expression of normal liver cells to that of cancer cells from a person with liver cancer. The scientists labeled the cDNA from the normal pancreatic cells with green fluorescent nucleotides. They labeled the cDNA from the cancer cells with red fluorescent nucleotides. The two cDNAs were mixed and allowed to hybridize to a microarray. Normal liver cells =Green Cancer cells =Red The DNA in that spot is the same in cancer cells and normal cells =Yellow Question: Gene alpha is turned on in all liver cells. In the cancer sample there is a nonsense mutation in this gene such that the protein terminates translation early but transcription is unaffected. What color is the alpha gene spot on the microarray? Answer: Yellow please explain why is the answer yellow?
You are studying a new gene “X” that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xf?? bp

What is the enzyme responsible for methylating DNA? How does a drug like doxorubicin affect DNA methylation?
Scientists modified the tumor-inducing (Ti) plasmid, a naturally occurring plant plasmid found in Agrobacterium tumefaciens, to create a tool used to introduce any gene of interest into plant cells. They created a binary system because a single Ti plasmid is too large to be easily manipulated. One part of the system is a disarmed plasmid, and the second part is a transformation vector. The following sentences describe the function of key DNA elements in the system. Virulence region Genes for conjugative transfer Disarmed Ti plasmid (T-region removed) ori Kan selectable marker plant selectable marker constitutive promoter T-region conjugative transfer virulence Kan (bacterial selectable marker) Amp selectable marker Plant selectable marker (e.g., herbicide resistance) Constitutive promoter T-DNA left border Place the terms in the appropriate blanks to complete the sentences. Not all terms will be used. 3' transcriptional terminator MCS (inserted gene of interest) T-region Transformation…
Xeroderma pigmentosum is a genetic disease caused by an error in the nucleotide excision repair process that fixes damage to DNA by ultraviolet light. Studies have shown that it can result from mutations in any one of seven genes. What can you infer from this finding? A) There are seven genes that produce the same protein B) These seven genes are the most easily damaged by ultraviolet light. C) There are seven enzymes involved in the nucleotide excision repair process. D) These mutations have resulted from translocation of gene segments.
