Germ-line mutations are mutations that would be passed down to future generations, and recombinations are where the information each parent passes down to the offspring is shuffled.
The genetic variation would have to come from random events: False
Only alternate generations would express any genetic variable: False
Body cell mutations would be the only source of heritable genetic variation: False
There would be no new heritable genetic variation possible in the population: True
Answer:
Transcription begins at a gene's promoter, a specific sequence of DNA that acts as a "start" signal for a gene that is to be transcribed. Transcription ends at a sequence of bases that acts as a "stop" signal.
Explanation:
Enzymes are organic catalysts which aid in facilitating chemical reactions in the body. When functioned properly homeostasis is maintained.
Answer
Characteristics of young rivers are;
• The river is small and flows with less energy down steep slopes
• Features formed are a result of erosion
• These rivers form V-shaped valley
• Form interlocking spurs when they meet obstacles
Explanation
A river in its youthful stages has a steep river gradient. The river is in most cases narrow and deep. Waterfalls and rapids are common in youthful stages of a river. The river channel is considered narrow and deep, with a V-shaped valley present. Vertical erosion is dominant and the channel of the river generally winds.
Answer:
Its is a lysosomal storage disease!
Explanation:
<u>Hurler syndrome:-</u> is also known as mucopolysaccharidosis-I .
It Is due to the mutation on chromosome 4 .
There is a lack of of enzyme called alpha-L-iduronidase.This enzyme is present in lysosomes
It causes accumulation of mucopolysaccharides because of the absent of the enzyme in the lysosome
<u>Hunter syndrome:- </u>is also known as mucopolysaccharidosis-II
It occurs due to mutation in iduronate-2-sulfatase (IDS) gene.It is an X-linked disease
