Based on the DNA strand below, and assuming the promoter for this gene is located to the le\, which protein sequence below does
Art [367]
<h2>Protein sequence</h2>

Explanation:

  • The given sequence is of coding strand(5'-3' direction)

5’-ATGTTGAAAATGCCGTAGAGGC-3’  

  • Protein is made up of mRNA and mRNA has the same sequence as coding strand(only T is replaced by U) so the sequence of mRNA will be:

5’-AUGUUGAAAAUGCCGUAGAGGC-3’

According to the genetic code,3 bases code for one nucleotide and further nucleotide codes for amino acid,amino acids forms the base for protein

  • AUG codes for Methionine(Met)
  • UUG codes for Leucine(Leu)
  • AAA codes for Lysine(Lys)
  • AUG codes for Methionine(Met)
  • CCG codes for Proline(Pro)
  • UAG codes for stop codon(Stop)

Once the stop codon comes protein synthesis will be stopped,so the final protein sequence will be:

Met-Leu-Lys-Met-Pro-Stop

What do you think are the scientific names for two atoms covalently bonded<br> together?
Troyanec [42]

The scientific names for two atoms covalently bonded are : Hydrogen and oxygen

<h3>Covalent bonding </h3>

Covalent bonding is the sharing of electrons between two atoms. This type of bonding occurs between two or more nonmetals.

Elements formed by covalent bonds are non-metal elements and the atoms that form covalent bonds are non-metal atoms. the scientific names of two atoms that are covalently bonded are ; hydrogen and oxygen to form water

H₂ + O = H₂O

Hence we can conclude that The scientific names for two atoms covalently bonded are : Hydrogen and oxygen.

Moderate amounts of alcohol _____. improve the body’s utilization of insulin and blood glucose
xxMikexx [17]

Moderate amounts of alcohol improve the body’s utilization of insulin and blood glucose. is true

  • Frequent heavy drinkers can deplete their energy reserves in a matter of hours.
  • Overindulging in alcohol over time can lessen insulin's overall efficiency.
  • As a result, blood sugar levels are elevated. However, many persons with alcoholic liver disease also have diabetes or glucose intolerance.
  • A lower risk of type 2 diabetes is associated with moderate alcohol usage, as opposed to abstinence and heavy drinking.
  • Despite the fact that both males and women's risks are decreased with moderate alcohol use, the associations between the two may be different.
  • Alcohol intake and type 2 diabetes may be linked, and this connection may be explained by adiponectin's actions, enhanced insulin sensitivity, or anti-inflammatory properties.

How gamete formation leads to genetic variation.​
galben [10]

Answer:

The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. ... At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
