Answer:
C) a sequence of nucleotides in DNA that codes for a functional product.
Explanation:
Gene -
Gene is a fixed portion present in the chromosome of the cell , which is inbuilt with the hereditary information of the cell .
Genes directs the synthesis of the proteins .
It is basically a sequence of nucleotides present in the DNA .
Hence , from the given options the correct statement for gene is ( c ) .
I believe the punnet square is showing the genotypes of the F2 generation. If that is true, the answer would be 3 red : 1 white. This is because the four genotypes are RR, Rr, Rr, and rr. Out of those, 3 contain the dominant allele R that codes for red, while only one contains both recessive alleles that code for white. Hope this helps!
Answer:
a. the RNA polymerase undergoes abortive initiation prior to promoter clearance
Explanation:
In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.
In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.
Most bacterial RNA transcripts do not undergo splicing.
The nucleosome is the basic unit of chromatin repeat in eukaryotes.
4. organism, organs, tissues, cells
Answer:
1. Óxidos são compostos binários formados pela reação do oxigênio com outros elementos.
2. Além disso, a tonificação também pode ficar feia e ocorrer em tons de preto e marrom. Nos casos mais graves, a tonalidade pode se transformar em corrosão e causar danos permanentes à superfície da moeda. Nos piores casos, a corrosão pode tornar a superfície da moeda porosa de tal forma que parece que foi tratada com jato de areia
3. (por exemplo, Li2O). Os óxidos são compostos binários de oxigênio com outro elemento, por exemplo, CO2, SO2, CaO, CO, ZnO, BaO2, H2O, etc. Estes são denominados como óxidos porque aqui, o oxigênio está em combinação com apenas um elemento.
