Answer:
c. Affected fathers have all affected daughters, but no affected sons.
Explanation:
Given that the disease is caused by a dominant allele on X chromosome, an affected father would have a disease allele in the X chromosome that passes along to the male gamete, while the gametes containing a Y chromosome would not have it (since it is X-linked).
During sexual reproduction, the father passes an X chromosome to its daughters (the second X chromosome being contributed by the mother) but an Y chromosome to its sons (the single X chromosome being contributed by the mother).
Indeed, within an affected father's offspring, all his daughters will receive the affected X chromosome from him, while his sons will receive an unaffected Y chromosome (since the disease is X-linked). These males will not inherit the disease, for they will receive an unaffected X chromosome from her mother (which is expected to be healthy since the disease is rare).
Answer:
Friedrich Miescher was the one who studied all about RNA.
Explanation:
Answer: The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline) is best supported by t<u>he specific transcription factors made in a cell.</u>
Explanation:
Genes store deoxyribonucleic acid or DNA that makes up the genome. The genetic information within genes is expressed through a process called transcription followed by translation.
During this, the genotype of the organism is changed into its phenotype or physical characteristics genes are controlled or regulated through certain molecular mechanisms These essentially determine transcription and translation and whether gene products is active or in active genes are turned on when they are able to transcribe the genome.
gene expression may be regulated
via
- modulation before or after the transcription process
- modulating translation
- modulation after translation
A control for the transcription process is called a transcription factor. These are DNA sequence specific proteins that are capable of activating or suppressing transcription at certain sites. In different cell types, different combinations of transcription factors contribute to gene expression.
The answer is true, Sponges can regenerate the entire organism from just a conglomeration of their cells. They can be cut up or mashed, and as long as they have two special cells called collencytes, which produce the gelatinous matrix in the sponge, and archeocytes, which produce all the other cells in the spongeâ??s body, the sponge will reform into the sponge it once was. Although, it will look different. Hope it helps!
