Answer:
a codon can be found on mRNA
Explanation: codons are created when groups of nucleotides are conected to form a animo acid. the formation is all in the mRNA then the animo acids combine to form proteins. proteins are formed when animo acids are "dehydrated" and form a water molecule then the rest combine into a protein and that protein can be in any form for various tasks.
Answer:
B. 26amu
Explanation:
The nucleus of an atom in an element contains protons, electrons and neutrons. The proton number equals the electron number in a neutral atom. The proton number is also called the atomic number, denoted by Z.
The mass number also called Atomic mass unit (amu) in this case, of an element is the sum of the proton number and the neutron number in the atom of that element. The mass number is denoted by A.
Hence, A = Z + N
Where A = Mass number
Z = Proton (atomic number)
N = Neutron number
In this question, N is 11 while Z is 15
Hence, the mass number of the element in the question, in AMU, is 15 + 11 = 26amu.
Explanation:
Bones shape our body and help is to stand up straight. Muscles are attached to bones, they help us walk and run and smile. All the bones in our body make up our skeleton - from the top of our skill to the tips of our phalanges at the end of our toes. Muscles stretch across our bones and are attached with tendons.
