Answer:
Contract
Explanation:
The main proteins involved in muscle contraction are called actin and myosin.
Mars, Mars supplies all the plants with carbon dioxide, since they have no oxygen of their own
Right receptor protein on the surface of the target cell or in cell plasma is required. There are three major types of receptors in cell:
1. Channel receptors- <span>neurotransmitters.</span>
2. Receptor tyrosine kinases-protein expression
3. G protein coupled receptors-<span>detect </span>substances<span> outside the </span>cell
Farming and the surplus of food allowed humans to focus on activities other than food production, which led to the division of labor and the creation of new social classes-True.
<h3><u>
Explanation:</u></h3>
Farming refers to those activities that are associated with the cultivation of crops and growing livestock. When the crops that are cultivated exceed the nation of a particular nation, then it leads to the surplus of food. In that situation, the governments will take necessary steps for storing the cultivated crops for the future usage.
When different works are allotted or assigned to different workers for the completion of certain tasks and also for improving the efficiency refers to the division of labors. When the Framing and the surplus of food exits it makes them to concentrate on the activities other than farming and this will increase the division of labor and the creation of new social class.
Answer:
mRNA: 3' AUG-AAU-GCU-GCC-GGU-GA-5'
amino acids : methionine, asparagine, alanine, arginine, proline
type of mutation: deletion, missense
Explanation:
The mRNA sequence is complementary to the DNA sequence. A always pairs with T, C always pairs with G. Except this is an RNA sequence not a DNA sequence, so T is replaced with U.
The mRNA sequence is translated into an amino acid sequence based on the triplet code. The triplet code for this sequence is shown in the attached picture. Each triplet signifies a specific amino acid. The codon can be identified from the table and placed in sequence. We can see that the new DNA strand has caused a new amino acid sequence. It has also left us with an incomplete sequence, as GA cannot signify an amino acid.
The type of mutation is a single base deletion. We can see that the base C is missing from the 9th amino acid in the original strand. As you can see, this has an ongoing affect on all the bases in the rest of the sequence, as it changes the way the sequence is organised into codons. This results in a missense mutation.
