The answer is D because the universe is always expanding
Answer:
Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. ... In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

Explanation:
The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.
Answer:
RNA sequence- 5' AUG 3',
tRNA anticodon- 3' UAC 5'
Amino acid- methionine
Explanation:
DNA contains two strands of sense and antisense. The mRNA sequence is produced by the antisense strand of DNA. So if the DNA sense strand has ATG sequence then according to the complementary base pairing the sequence against it would be 3' TAC 5'.
In RNA in place of thymine, Uracil comes so here according to complementary base pairing rule the sequence of codon in RNA would be 5' AUG 3'. As tRNA contains anticodon sequence which is complementary to mRNA codon sequence therefore the anticodon sequence would be 3' UAC 5'.
Every triplet codon in mRNA codes for a particular amino acid and AUG codon is called start codon which codes for methionine. So methionine would be added against AUG codon.
Answer:
See the explanation.
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments by size and charge. Electrophoresis consists in applying a current through a gel that contains the molecules of interest. Based on their size and load, the molecules will travel through the gel in different directions or at different speeds, thereby separating each other. All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis separates DNA fragments only by their size.
Electrophoresis allows us to see how many different DNA fragments are present in a sample and how large they are with respect to each other. We can also determine the absolute size of a DNA fragment by examining it next to a standard "scale" of fragments of known size.
Hope this helps!
