This statement is true. To be more specific, the calcium ions bind to the troponin, which are attached to the protein tropomyosin. The tropomyosin then to shifts to expose the actin filaments to which myosin heads need to bind to produce contraction.
Anticodons are a part of transfer RNA(tRNA) molecules, and corresponds to a codon on a messenger RNA(mRNA) molecule.
Your answer is A, anticodon; codon.
Answer/Explanation :
A heterozygous cat has a genotype Hh
A hairless cat has a genotype hh
When crossed, the results could be any of the following:
Hh (with hair)
hh (hairless)
There is a 50:50 chance or 1: 1 ratio that the offspring will have hair.
Answer:
C. Point mutations
Explanation:
Point mutation involves the insertion or deletion of a base pair or the substitution of a single base for another in a gene. Point mutation rarely cause a significant change in a gene.
<em>Gene duplication involves the repetition of a gene-containing DNA region in an organism. It can result from errors in DNA replication/repair and other circumstances in the cell.</em>
<em>Horizontal gene transmission involves the transmission of gene-carrying DNA materials between different genomes of different species of organisms.</em>
<em>Transposable elements are regions of DNA that have the ability to move from one place to another within the same genome. They often create a kind of mutation and change the genetic identities of cells. </em>
The correct option is C.
