Answer: it’s fertilization
Explanation: Fertilization in flowering plants happens through a process called pollination. ... Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. • Each seed contains a tiny, undeveloped plant called an embryo.
Answer:
ACA: Threonine
CAC: Histidine
Explanation:
To answer this question we need to remember that the ribosome reads every three bases or 'codon' in order to assign the right tRNA carrying the amino acid.
In the first artificial mRNA we see two patterns of three letter:
CAC and ACA.
In the second artificial mRNA we are able to identify three different patterns:
CAA
AAC
ACA
And they repeat, so we end with three different polypeptides: polythreonine, polyglutamine and polyasparagine. This will depend on the initial letter the ribosome starts reading.
The only amino acid that repeats in both artificial mRNAs is Threonine, and we see its pattern ACA also repeated.
So, we could assign this codon (ACA) to threonine.
We can then assume that the pattern CAC codifies for histidine since we only get this two polypeptides in the first mRNA.
Lastly with the information provided we cannot determine the codons AAC and CAA for glutamine or asparagine. We would need further experiments.
Answer:
The correct answer is There is one factor salt(restricted, unrestricted).
Explanation:
Vegetarian diet and low salt diet are both promising in the treatment of hypertension or high blood pressure.
In the given question there is only factor that is variable that is restricted salt and unrestricted salt .
This is because both normal diet and vegetarian diet are same that"s the term diet is not variable.
The right answer is: neutral mutation.
Neutral mutation is a nucleotide change in the DNA of the leading to the replacement of one amino acid by another amino acid possessing the same physicochemical properties.
example: AAA to AGA (Lysine to Arginine).
both these two amino acids are positively charged, so the charge of the protein will not change
