How is a protein made?

Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

What contains instructions for making a protein that are later carried by RNA?

The central dogma of molecular biology states that DNA contains instructions for making a protein, which are copied by RNA. RNA then uses the instructions to make a protein.

What are three examples of protein foods?

The two main food groups that contribute to protein are the:

  • ‘lean meat and poultry, fish, eggs, tofu, nuts and seeds and legumes/beans’ group.
  • ‘milk, yoghurt, cheese and/or alternatives (mostly reduced fat)’ group.

What is the first step of protein synthesis called?

Transcription
PART A. Read the following: Protein synthesis is the process used by the body to make proteins. The first step of protein synthesis is called Transcription. It occurs in the nucleus. During transcription, mRNA transcribes (copies) DNA.

What stores build proteins?

DNA
The information to make proteins is stored in an organism’s DNA. Each protein is coded for by a specific section of DNA called a gene. A gene is the section of DNA required to produce one protein.

Which fruit is highest in protein?

High-protein fruits

  • Guava. 4g protein per cup. Guava is number one on our list of high protein fruit.
  • Avocado. 4g protein per cup.
  • Apricots (dried) 2g protein per cup.
  • Kiwifruit. 2g protein per cup.
  • Grapefruit. 2g protein per cup.
  • Blackberries. 2g protein per cup.
  • Melon. 1.5g protein per cup.
  • Peach. 1g protein per cup.

What are the 2 types of protein?

There are two main categories (or sources) of proteins – animal and plant based. Animal proteins include: Whey (dairy) Casein (dairy)

What are the 7 steps of protein synthesis?

What are the 7 steps of protein synthesis?

  • DNA unzips in the nucleus.
  • mRNA nucleotides transcribe the complementary DNA message.
  • mRNA leaves nucleus and goes to ribosome.
  • mRNA attaches to ribosome and first codon is read.
  • tRNA brings in proper amino acid from cytoplasm.
  • a second tRNA brings in new amino acid.

What are the 5 steps of protein synthesis?

Terms in this set (5)

  • Unzipping. – DNA double helix unwinds to expose a sequence of nitrogenous bases.
  • Transcription. A copy of one of the DNA strand is made.
  • Translation (Initiation) mRNA couples w/ ribosome & tRNA brings free amino acids to ribosomes.
  • Elongation. – Anticodon of tRNA recognizes codon on mRNA.
  • Termination.

What is an example of protein synthesis?

When protein synthesis is taking place, enzymes link tRNA molecules to amino acids in a highly specific manner. For example, tRNA molecule X will link only to amino acid X; tRNA molecule Y will link only to amino acid Y. Messenger RNA is synthesized in the nucleus using the DNA molecules.

Does DNA control the production of protein?

16 How do genes direct the production of proteins? The information to make proteins is stored in an organism’s DNA. Each protein is coded for by a specific section of DNA called a gene. A gene is the section of DNA required to produce one protein.
